Deriving value from the adoption of emergent technologies in the supply chain management
Dissertation directed by Professor Dawn Gregg
ABSTRACT
Emergent technologies such as blockchain, Internet of Things, and Artificial
Intelligence have been utilized in recent years by supply chain firms. This research consists of
two studies that examine emergent technologies' impact on supply chain management. The first
study follows a systematic literature approach that investigates the reliability impact of
blockchain on supply chain management practices (SCMPs)including practices on both sides
of the supply chain, upstream (e.g., supplier partnership), downstream (e.g., customer
relationships), and practices related to both sides (e.g., information sharing and information
quality). The result of this study will provide the current state of blockchain adoption in the
supply chain context. Specifically, this study will provide a structure for the relationship between
blockchain and SCMPs as a reference for future research by theorizing blockchain for SCMPs
from the perspectives of Resource-based View and Practice-based View. The second study
empirically examines emergent technologies' role in reducing the bullwhip effects. Prior studies
found that IT can significantly reduce the bullwhip effects for overall industries. This research
extends previous studies by focusing on an intelligent tool integrated with emergent technologies
such as blockchain, IoT, and AI as the best practice for reducing the bullwhip effect. The results
of this study indicate that integrated emergent technologies such as blockchain, IoT, and AI
reduce the bullwhip effect for retailers but increase it for manufacturers. In addition, both studies
contribute to the information systems discipline by providing supportive guidance for emergent
technologies' managerial and practical impacts on the supply chain. The first study contributed to
v
the supply chain management practice by highlighting the associated SCMPs with blockchain
technology and conditions when considering the adoption of blockchain technology for SCMPs.
Also, I contribute to the theory by theorizing blockchain technology for SCMPs from the
perspectives of Resource-based View and Practice-based View. In the second study, I
contributed to the literature by examining the impact of emergent technologies in solving
bullwhip effects phenomena at the firms’ level rather than the industry level. Also, I
distinguished between firms’ industries in the analysis as firms’ sectors matter in the supply
chain environment.
The form and content of this abstract are approved. I recommend its publication.

Chapter I
INTRODUCTION
In recent years, emerging technologies, such as blockchain, Internet of Things (IoT), and
Artificial Intelligence (AI), rapidly emerged as tools to support supply chain management. As
emergent technologies evolve, they allow supply chain firms to become more integrated with
their business partners for efficient outcomes. Therefore, the technologies have attracted the
attention of researchers and scholars begun to investigate the benefits and challenges of emergent
technologies to the supply chain. Emergent technologies support the traceability of materials
flow in the supply chain and allow information sharing among partners. In this manner, they
allow supply chain firms to have more accurate data to rely on for decision-making about supply
chain processes, such as production, distribution, inventory management, and market demand.
In this context, this study investigates the impact of emergent technologies on supply
chain management. Specifically, this research consists of two studies. The first study highlights
the value of adopting blockchain technology for Supply Chain Management Practices (SCMPs).
I focus on eight practices related to both upstream and downstream of the supply chain, namely,
joint product development, purchasing alliances, vendor-managed inventory, strategic supplier
partnerships, customer relationships, information sharing, information quality, and
postponement. A previous study demonstrated scenarios pre and post-implementation of
blockchain integration with smart contracts and found significant improvements to the supply
chain performance after implementation (Manupati et al. 2022). However, previous studies lack
details on which practices can improve supply chain performance. Organizations lack the
information necessary to decide when they should or should not adopt blockchain as a part of
their supply chain (Okorie et al. 2022). Following the gap found by Okorie et al. (2022), this
2
study guides inter-organizational networks when considering blockchain adoption toward certain
SCMPs. Further, it contributes to information systems and supply chain literature by guiding
supply chain firms when considering blockchain adoption for SCMPs and under certain
conditions. In addition, this study theorizes the integration of blockchain technology for SCMPs
using the theoretical lenses of the Resource-based View (RBV) and Practice-based View (PBV)
to examine why blockchain can be beneficial to some supply chain firms but harmful to others
under some circumstances.
According to the RBV, resources and capabilities should be rare, inimitable, and not
substitutable (J. Barney 1991). The PBV refers to imitable and flexible practices that can be
relocated across organizations’ domains (Bromiley and Rau 2014). In this case, blockchain is
considered a capability that can integrate internal and external processes within the supply chain,
whereas the SCMPs are considered imitated practices and compatible with the PBV.
The second study focuses on emergent technologies' role in reducing the bullwhip effect.
The bullwhip effect is a critical issue for supply chain firms; it can lead to inefficient supply
chain performance. Bullwhip effects refer to the order to the supplier (manufacturer) being larger
than the demand from sales (buyer) (Lee et al. 1997), which results in increasing production and
inventory costs. According to Lee et al. (1997), four leading causes of the bullwhip effects are
demand signaling, order batching, fluctuating process, and shortage game. Since emergent
technologies can revolutionize business transactions in many industries, including supply chain
firms, this study attempts to investigate the impact of intelligent tools that integrate emergent
technologies with supply chain systems.
Furthermore, scholars summarized the effectiveness of integrating enterprise systems
with emergent technologies. For example, recording information using IoT devices, sharing it via
3
blockchain's ledgers, and storing it in big data to be used by companies for future planning and
decision-making (Sundarakani et al. 2021). Also, the involvement of AI and smart contracts
within the supply chain industry supports decision-makers and automation processes (Arunmozhi
et al. 2022). Therefore, this study empirically examines whether emergent technologies reduce
the bullwhip effect for manufacturers and retailers. This study helps resolve the bullwhip effect
phenomena seen in prior studies by examining the impact of emergent technologies on retailers
and manufacturers.
The results from both studies will provide supportive guidance for supply chain firms on
when they should or should not adopt emergent technologies. This dissertation study is expected
to contribute to the information systems literature by providing the fulfillment conditions that
benefit the adoption of emergent technologies in the supply chain industries. In the first study, I
provide themes and exemplary research questions for researchers to investigate the gaps in the
literature for adopting blockchain technology for supply chain management. A theoretical
framework was provided based on the lenses of RBV and PBV to examine the impact of
blockchain on supply chain performance when integrated with SCMPs. Also, I provide guidance
for practitioners on the opportunities and conditions of blockchain adoption for SCMPs.
In the second study, I demonstrated evidence for supporting emergent technologies in
reducing bullwhip effects at the firm level rather than the industry level and distinguished
between firms’ industries sectors in the analysis. The findings of this study encouraged retailers
to adopt emergent technologies for their supply chain to enhance operational efficiencies through
equilibrium between orders and demand and improve inventory management.
The remainder of this study is organized as follows: Chapter II presents the first study
that investigates the adoption of blockchain technology for SCMPs and under which conditions
4
blockchain could benefit supply chain firms. Chapter III presents the second study that
empirically examines the impact of emergent technologies in reducing the bullwhip effect for
northern American public firms.

Chapter II
The Adoption of Blockchain Technology for Supply Chain Management
Practices: A Systematic Literature Review
Introduction
A digitalizing supply chain is essential for several industries, including pharmaceuticals,
agriculture, chemicals, etc., across all industries sectors. Firms aim to share product information
in the supply chain to enhance information quality (Li and Lin 2006) and transparency (Zhu et al.
2017). As a solution, blockchain adoption in the supply chain has dramatically increased in
recent years to support business partners in sharing information. Blockchain consists of ledgers
storing and sharing transactions in a decentralized database (Du et al. 2019; Scholz and Stein
2018). Integrated blockchain with enterprise systems allows firms to track products during
transportation processes and enable information sharing. However, the impact of blockchain on
supply chain activities varies based on the blockchain’s role that is held in the supply chain.
Orlikowski and Iacono (2001) argued that research on IT artifacts should get attention
from scholars in all fields without considering its epistemological perspective or methodological
tendency. They also encouraged researchers to theorize about IT artifacts to understand
exceptional technologies. Thus, the concept of blockchain was first developed by Nakamoto
(2008) in a white paper. The technology was developed for the cryptocurrency Bitcoin, which
uses peer-to-peer nodes in electronic cash systems. Since then, organizations have explored the
benefits of emerging blockchain technology in their business applications. Also, scholars have
examined the potential uses of blockchain in various domains, such as e-commerce (Kumar et al.
2020; Zhou et al. 2021), healthcare (Agrawal et al. 2022; Jadhav and Deshmukh 2022),
6
agriculture (Eluubek kyzy et al. 2021; Oguntegbe et al. 2022), and online advertising (Yayla et
al. 2023).
Existing studies have addressed the roles of blockchain in meeting supply chain
objectives such as cost, speed, quality, sustainability, and flexibility (Kshetri 2018). Lacity and
Khan (2019) highlighted managerial challenges of blockchain adoption, including intellectual
property, shared governance, espionage risks, and regulatory uncertainty. However, this study
aims to investigate the relationship between blockchain and supply chain management practices
SCMPs, as shown in Figure 1. Various studies have proposed blockchain-based applications to
emerge in the supply chain context, but no studies specifically synthesize blockchain's impact on
SCMPs. Blockchain technology is considered effective in the supply chain environment to
improve performance and operational efficiencies (Kshetri 2018; Tönnissen and Teuteberg
2020). Moreover, the role of blockchain in the supply chain sheds light on supply chain
sustainability (Kshetri 2021) and reduction in carbon emissions (Sundarakani et al. 2021). To
identify relevant research on blockchain integration with SCMPs in information systems and
supply chain management literature, I formulated the following research questions:
RQ1: How effective is blockchain technology in addressing issues related to different
supply chain management practices?
RQ2: Under which conditions do organizations or inter-organizational networks adopt
blockchain to support certain supply chain management practices?
In addition, following the suggestion of Orlikowski and Iacono (2001) to theorize IT artifacts
without considering their epistemological perspective or methodological tendency, this study
aims to theorize blockchain technology for SCMPs. Hence, I developed the following research
question:
7
RQ3: What theory or theories can assist scholars and practitioners in adopting
blockchain for SCMPs?
To answer these research questions, this study followed a systematic literature review approach.
A literature review of IS journals and closely related fields provide a scope view of blockchain
technology involvement in the supply chain environment. This approach allowed to achieve four
research objectives:
1) Provide an overview of existing research on the blockchain usage for certain SCMPs.
2) Understand the required conditions of blockchain adoption to benefit supply chain
firms.
3) Develop a framework of related impacts of the blockchain to SCMPs.
4) Derive opportunities for future research in adopting blockchain for supply chain
management.
Addressing these research questions will contribute to information systems and supply
chain management by providing guidance on when blockchain should be adopted for SCMPs
and under which conditions. This enables the research results to identify the distinctiveness of
each practice and interpret a comprehensive understating of blockchain technology adoption for
SCMPs. Also, theorizing blockchain for SCMPs can assist future research in exploring the actual
impact of blockchain on SCMPs.
The next section discusses the theoretical background of the blockchain and SCMPs. The
methodological approach of the systematic literature review process is explained in detail,
including the searching process, collecting, and analyzing the literature. Subsequently, this study
presents a theoretical framework based on the literature results and provides practical, research,
and theoretical implications. The final section included a discussion regarding findings, provide
8
practical guidance on the conditions for blockchain adoption, and provided recommendations for
future research opportunities.

Theoretical Background
Blockchain and Inter-organizational Systems
Orlikowski and Iacono (2001) found that IT artifacts are dynamic and emerging
technologies from developing social and economic practices. Blockchain is an emerging
technology that is influencing a wide range of inter-organizational practices in a variety of
domains and industries. It can be used to process information when integrated with inter-
organizational systems. Inter-organizational requires two or more organizations to be mutually
effective in certain activities (Carter et al. 2017). Li and Lin (2006) refer to inter-organizational
relationships as the degree of trust, commitment, and collaboration between business partners.
Moreover, a study in information systems investigated the rationality of information systems
interactions across organizations. Collaboration and trust between organizations are crucial to
interpreting this interaction (Kumar et al. 1998). Thus, deploying blockchain with an inter-
organizational network removes the need for trust by enforcing manipulation of the contents and
increasing transparency (Davidson et al. 2016). Ideally, blockchain requires inter-organizational

collaboration and integration with existing enterprise systems to derive value for business
partners (Labazova 2019; Lacity and Khan 2019).
Supply Chain Management Practices
Scholars have defined SCMPs as operational functions and activities that can capture the
degree of imitability and determine the supply chain's effectiveness and efficiency (Carter et al.
2017; Kaliani Sundram et al. 2016). For example, Zhou & Benton (2007) identified three
components: supply chain planning, just-in-time production, and delivery practice. However,
existing studies have distinguished the components of SCMPs based on the side of the supply
chain (e.g., upstream and downstream). An example of upstream practices can include activities
with suppliers, such as procurement and supplier partnerships, while customer relationship is an
example of the downstream side. Information sharing and information quality are considered
practices related to both supply chain sides (Jum’a et al. 2021).
The variety of SCMPs in the supply chain literature is wide such as just-in-time
production, strategic planning, delivery practices (Banker et al. 2006; Tan et al. 2002; Zhou and
Benton 2007), agreed vision and goals, and risk and reward sharing (Kaliani Sundram et al.
2016). Several studies have reviewed the broad scope of SCMPs including Carter et al. (2017),
Jum’a et al. (2021), Li et al. (2006), and Zhou and Benton (2007). These studies have highlighted
eight sustainable supply chain practices which are outlined in Table 1 below. These eight
practices are joint product development, purchasing alliances, vendor-managed inventory,
strategic supplier partnership, customer relationship, information sharing, information quality,
and postponement. Carter et al. (2017) identified two additional practices, namely, product return
processing and logistic process outsourcing; however, these practices were not included in Table
1 due to the low expectation regarding their impact on the efficiency of supply chain activities
(Zhou and Benton 2007). Also, I did not include supplier development practice from Carter et al.
10
(2017); it refers to the selection of suppliers, which overlaps with the strategic supplier
partnership (Li et al. 2006). Table 1 briefly explains these practices with definitions along with
literature sources.

Blockchain and Supply Chain Research
This section illustrates the recent development of blockchain technology in supply chain
research and the capability of blockchain to improve supply chain efficiencies. Scholars have
recommended pursuing blockchain adoption for supply chain management to engage in the
modern supply chain. Blockchain technology can support decision-makers by strengthening
communication between supply chain partners (Rejeb et al. 2021), enhancing trust (Verhoeven et
al. 2018), and achieving disruptive transformation in a digital supply chain environment
(Korpela et al. 2017). The technology can significantly achieve supply chain objectives by
enabling traceability within the supply chain and enhancing quality and performance (Kshetri
2018; Kshetri and Loukoianova 2019). For example, Tian (2016) developed a blockchain-based
and RFID traceability system for the agricultural industry. The system can gather and share
information on products’ provenance during supply chain processes, enhancing the quality and
safety of agricultural products.
In recent years, blockchain technology integration in Industry 4.0 for supply chain
management has dramatically increased to improve operational processing efficiencies. For
example, Mehta et al. (2021) developed a blockchain-based system to create royalty contracts
between stakeholders in the oil and gas industries. The system was evaluated, and it provides
successful functionality to the industries. Furthermore, Sundarakani et al. (2021) conducted two
case studies that integrated big data and blockchain in the supply chain environment. The first
study failed to meet supply chain objectives in cross-border cargo movements due to
disconnected systems and services, including sixteen different ERP systems. In contrast, the
second case study, which is the successful case, increased the firm’s revenue by 25% after
blockchain implementation through customer service by enabling real-time data sharing.

Methodology and Research Design
Research Design
A systematic literature review is a widely used methodology in the information systems
field to synthesize the role of information technology at the organizational level (Dincelli and
Yayla 2022; Mamonov and Peterson 2021; Tallon et al. 2019). This methodology aims to
achieve high transparency in the search processes and comprehensively cover the topic from
previous published scholarly research (vom Brocke et al. 2009; Okoli 2015; Webster and Watson
2002).
This research involves a systematic literature review using the five-step processes
proposed by vom Brocke et al. (2009), see Figure 2. I conducted this review to explore the
integration of blockchain with SCMPs. To adequately address the research questions, I reviewed
the literature on information systems, supply chain management, and other related areas because
blockchain’s theoretical underpinning is a distributed ledger that requires inter-organizational
systems (Labazova 2019; Lacity and Khan 2019), and its involvement in impacting supply chain
management (Treiblmaier 2018). Thus, it is essential to combine literature to determine
blockchain's contribution to other fields. With this condition, I search for emerging blockchain
technology in the supply chain, whether integrating with inter-organizational systems, enterprise
resource planning, material requisition planning, or e-commerce systems.

In total, 799 studies were identified from all databases after all duplicates were removed,
as shown in Table A1 (Appendix A). I carefully reviewed each study and removed unrelated
studies, including:
non-peer-reviewed articles,
in-progress papers, reports, call for research, and research proposals,
editorial comments, panels summary reports from conferences,
studies that were not related to the impact of blockchain on the SCMPs (e.g., the
use of FinTech, Bitcoin), and
unrelated studies to information systems or supply chain management according
to the journal focus areas and the purpose of the study.
After excluding unrelated studies, 112 articles from scholarly journals remain for review. Figure
3 shows the process of the selected articles for review.
15
Figure 3: Selected Review Articles Process
The varieties of the journal disciplines are broad in this literature due to the capability
and flexibility of blockchain in emerging into multiple disciplines for supply chain processes.
Table A2 (Appendix A) shows the list of journals and the number of associated studies in the
review for each journal. Thirty-four journals are within information systems or related fields,
such as management and computer science applications, with eighty-four total studies in these
journalssix journals related to the supply chain management and logistics discipline, with
sixteen total studies in the literature. The remainder of the journals and literature studies are
related to other fields, such as agriculture, food science, health, and engineering, but they all
interpret the benefits of blockchain adoption for SCMPs.
Review Analysis
I summarized the key findings, variables of interest, theory, and methodology of each study
and classified them into four groups by following Jadhav and Deshmukh (2022) classification of
the review papers. However, I include an additional classification (combined classifications) as
16
some studies combine more than one classification. Appendix B contains four classifications
tables that were categorized based on the following dimensions:
Table B1 conceptual studies: the research is a review paper that examines the idea of
blockchain in the supply chain by providing proof of its effectiveness.
Table B2 combined studies: the research provided a prototype or a model of blockchain
creation and practically deployed the solution.
Table B3 implementation studies: the research has deployed a practical evaluation of
blockchain technology in the supply chain.
Table B4 model or prototype studies: the research provided a prototype or a model
creation of blockchain-based technology.
Next, I analyzed all papers that mention or elaborate on the implementation of blockchain in
the supply chain regarding the following two dimensions:
1) Supply chain practices: I examined which practice/s that blockchain has impacted, then
identified whether the impact referred to: Joint product development, purchasing alliances,
vendor-managed inventory strategic supplier partnership, customer relationship, information
sharing, information quality, or postponement.
2) Purpose of blockchain implementation: I identified whether the article discussed the purpose
of blockchain implementation. In other words, which practice/s are influenced by
organizations or inter-organizations to implement the blockchain, and under which
conditions.
The categorization of the above dimensions related to the supply chain practices and the
purpose of blockchain implementation was the first step in analyzing the relevant articles. The
specification of the first dimension assists in determining which practice/s are supported when
17
implementing blockchain technology. In some studies, there are multiple practices impacted by
blockchain implementation. In the second dimension, articles that elaborate and discuss the
purpose of blockchain implementation assist us in understanding the motivation of blockchain
implementation and whether organizations or inter-organizations have influenced SCMPs to
adopt blockchain. Table C1 (Appendix C) summarizes the total studies found for each SCMP
and classifications in the literature review. Forty-four studies examined more than one practice
within the same study, and twenty-four studies discussed the conditions of blockchain adoption
for supply chain management. The results of the literature review are discussed in the next
section.
Results of the Systematic Literature Review
This section summarizes the results of the systematic literature review. Section 4.1
separately specifies each practice in Table 1 to answer the first research question: Which supply
chain management practices have blockchain been adopted for and supported? Section 4.2 is
related to the second research question: Under which conditions do organizations or inter-
organizational networks adopt blockchain to support certain supply chain management
practices? According to the literature studies, not all papers discussed the conditions of adopting
blockchain. Thus, based on those papers, I summarized the conditions for adopting blockchain
within this section.
The Association of Blockchain Technology to the SCMPs
Joint Product Development
Joint product development represents the participation of suppliers with firms to develop
a new product or service within the supply chain (Carter et al. 2017; Stuart 1997; Zhao and Cao
2015). New product development involves innovating unique products or developing existing
products (Liu et al. 2020). Three articles examine the use of blockchain for joint product
18
development practice. The first of these articles, Cole et al. (2019), examined the use of
blockchain in operation and supply chain management in the context of developing new
insurance products, such as smart contracts that can manage automatic payment to policyholders
when payment is due. They found that blockchain enhances efficiency in the supply chain in this
context.
Similarly, Benzidia et al. (2021) examined the role of blockchain in exploring innovation
management for the Industry 4.0 era. They defined innovation as the ability to accelerate,
improve, and develop processes for new product development. They found that the internal
integration of blockchain is significant and has a positive relationship with the innovation
processes. Specifically, blockchain can contribute to developing and improving processes in the
supply chain (Benzidia et al. 2021).
The third study investigates using blockchain to store and share information on the used
products for remanufacturing operations (Xu et al. 2023). The product information shall be
collected through a third-party firm selling its products online, such as JD.com and
Amazon.com. They found that manufacturers can increase profit when using blockchain to
remanufacture products and cooperate with online channels such as JD.com. Also, using
blockchain to remanufacture used products can contribute to reducing carbon emissions, which is
beyond the focus of this study. The results of these three studies suggest an opportunity for
blockchain to contribute to product development by enhancing efficiency in the supply chain
(Cole et al. 2019) and creating opportunities for firms to improve operational processes
(Benzidia et al. 2021).
Purchasing Alliances
The strategy of buying raw materials for production or trading goods to sell goods in the
market varies from one firm to another. Organizations need to build a trustworthy relationship
19
with their suppliers for supply-related strategy (Carter et al. 2017; Stuart 1997). Supply-related
processes can include procurement, purchasing, transporting, and holding processes. During
these processes, information leakage could result in faulty information being shared between
business partners (Yadav and Prakash Singh 2022). Hence, blockchain can be adequate for the
purchasing alliances practice in the supply chain and create a trustworthy relationship between
business partners (Raj et al. 2022). Six studies in the literature review investigated this
purchasing alliances practice.
Yadav and Prakash Singh (2022) designed an integrated digital procurement model with
the blockchain to endorse immutable information within the supply chain. The model was
verified and authenticated in solving procurement problems such as fraud, theft, and obscurity in
the supply chain. Raj et al. (2022) demonstrate a blockchain-based smart contract for
procurement and product traceability, which allows tamper-proof payment between buyers and
suppliers through third-party logistics.
In contrast, Nodehi et al. (2022) designed an e-procurement ecosystem for supply chain
stakeholders using enterprise blockchain. The system was applied to a proposed project for an e-
procurement platform and has been highly suitable for the proposed ecosystem. E-procurement
processes start by creating tender procedures by the buyers and end by signing the contract
digitally for suppliers and buyers. Using blockchain can reduce fraud and risks during e-
procurement processes. Also, it can reduce procurement and ordering costs by eliminating
intermediaries between buyers and suppliers, which allows them to depend on smart contracts
(Chang et al. 2021). The adoption of blockchain allows stakeholders to record and share
information, track transactions, and provide more security awareness. (Nodehi et al. 2022).
20
Moreover, blockchain-based smart contracts have been used for the oil and gas supply
chain to manage production, traceability, and purchasing activities. From the purchasing
perspective, Ahmad et al. (2022) found a successful adoption of blockchain for the purchasing
coordination of granting oil and gas exploration and production. Procuring oil and gas equipment
for exploration and production can sometimes be very complex. For example, equipment
installation and infrastructure development sometimes need to be globally procured and shipped
over the seas through business partners with different competing interests. Hence, using
blockchain to procure equipment can be made safer by enabling tracking of the equipment and
securely forwarding a procurement request to the suppliers. As a result of purchasing alliances
practice, blockchain can build trust between business partners in the supply chain for
procurement processes through third-party logistics.
Vendor-managed Inventory
Vendor-managed inventory practice refers to suppliers (vendors) who make production
decisions and maintain inventory availability across the supply chain (Carter et al. 2017; Fang et
al. 2008; Waller et al. 1999; Zhou and Benton 2007). Blockchain allows companies in the supply
chain to manage their inventory because transparency is high among supply chain partners
(Yadav and Singh 2020). Forty-nine studies in the literature review investigated vendor-managed
inventory practice. Most literature search results of this practice focused on the traceability of
food and pharmaceutical products within the supply chain to ensure quality and safe delivery of
the products. A few research studied the impact of blockchain on inventory management from
circular economy perspectives (Centobelli et al. 2022; Erol et al. 2022; Yontar 2023), and
tracking the provenance of the tangible asset (Sheldon 2022; J. Xu et al. 2023). In circular supply
chain, blockchain has proven its capability to improve the traceability management of products’
return (Centobelli et al. 2022; Erol et al. 2022) and its ability to contribute to the circular
21
economy of the agricultural food by tracking products' lifecycle and enhance food security
(Yontar 2023).
Sheldon (2022) designed a blockchain framework that integrates with an ID tag and IoT
devices, allowing tracking of the ownership and provenance of tangible assets. J. Xu et al. (2023)
developed a framework to trace steel materials in the construction industry using IoT devices and
blockchain. An application was also designed within the same framework to monitor and manage
supply chain processes such as quality, safety, payment, and logistics. Similarly, blockchain
proved its capability to trace equipment for multiple industries, such as airplane parts (Ho et al.
2021), oil and gas (Ahmad et al. 2022), all of which have the potential to trace food in the supply
chain (Bager et al. 2022; Bumblauskas et al. 2020; S. Cao et al. 2022; Y. Cao et al. 2022; George
et al. 2019; Teodorescu and Korchagina 2021).
In addition, the Drug Supply Chain Security Act (DSCSA) requires the pharmaceutical
industry, including manufacturers, distributors, and dispensers, to trace and share information
about prescriptions while they are distributed in the United States
1
. The DSCSA requires the
pharmaceuticals supply chain to implement an electronic system that can track data and trace
prescription medicine in the supply chain by 2023. Blockchain is a proper technology that can
fulfill the act’s requirements (Lacity 2018). Therefore, studies on the adoption of blockchain
within the pharmaceutical industry have increased since then in responding to the act’s
requirements. Mattke et al. (2019) explain how to deliver safe prescriptions and prevent
counterfeit drugs in the supply chain based on the Medi-Ledger project, which is a blockchain-
based application. Furthermore, recent studies addressed issues in the vaccine supply chain, such
1
The Center of Supply Chain Studies (CSCS) published a white paper “Drug Supply Chain Security Act and
Blockchain” on June 21, 2018. The paper can be found at the following hyperlink:

22
as counterfeit and vaccine expiration (Hu et al. 2023; Sreenu et al. 2022; Yong et al. 2020); and
drug supply chain (X. Liu et al. 2021; Teodorescu and Korchagina 2021). Hence, researchers are
rivaling to propose, design, and develop blockchain-based systems to address and resolve such
issues. For instance, Boubeta-Puig et al. (2021) integrated blockchain with supply chain systems
that can address critical situations such as recording freight containers' graphical locations and
room temperatures. The system was evaluated based on a real-world case study.
In sum, blockchain plays a significant role in logistics services by improving transaction
processing and allowing shipment traceability within the supply chain (Ahmad et al. 2021). For
instance, Yadav and Singh (2020) and Kamble et al.( 2020) empirically examined the
relationship between improvement in inventory and one of the blockchain’s characteristics,
which is the visibility and traceability of products in the supply chain. Both studies found
blockchain implementation's significant and positive impact on the supply chain. Overall, the
quality improvement of products or services can be gained by digitizing processes within the
supply chain (Markus and Buijs 2022), which complies with the best practice of managing
inventories.
Strategic Supplier Partnership
Collaboration between supply chain partners leads to sustainable and operational
efficiencies through technologies and communication platforms (Li et al. 2006; Tan et al. 2002).
Hence, blockchain technology enhances trustworthy relationships with business partners by
providing reliable information (X. Xu, He, et al. 2023). Ten studies in the literature review
investigated the strategic supplier partnership practice. For example, Agrawal et al. (2021)
investigated the potential impact of blockchain traceability systems on strengthening suppliers'
partnerships in the textile supply chain. The system enhances trust between business partners by
authenticating transactions at the operational level, such as transporting cotton from yarn
23
manufacturer to fabric manufacturer. Each transaction is monitored by a certifying agency with
the authority to correspond with the blockchain-distributed ledgers within the supply chain.
Blockchain promotes coordination between business partners through transparency and
information availability. For example, Kumar et al. (2020) provide a blockchain-based model
that allows stakeholders to access product information and validate the accuracy of the shared
information. Fosso Wamba et al. (2020) empirically found a significant positive relationship
between blockchain and supply chain performance. However, only one item related to the
trading partners was used in the performance measurement, which makes it insufficient proof
that blockchain could enhance the suppliers’ relationships. Niu et al. (2022) found that
manufacturers who re-produce products are willing to adopt blockchain. In contrast, their
suppliers do not prefer blockchain adoption unless specific circumstances are attained, such as
ensuring the ignorance of consumers’ risk aversion or at least a low degree of customers’
uncertainty about the quality of the remanufactured products.
Moreover, based on Y. Cao et al. (2022) analysis, a blockchain-based platform is not
beneficial to cooperatives in the supply chain under a revenue-sharing contract. The result
indicates that a high revenue-sharing ratio is not beneficial to cooperatives as it leads to a decline
in the total profit of the supply chain. They also found that the value of blockchain-based
platforms decreases while the ratio of revenue-sharing increases.
Customer Relationship
The customer relationship practice refers to retaining the relationship with customers
before and after sales or services provided to ensure sustainability of loyalty and satisfaction (Li
et al. 2006; Tan et al. 2002). Thus, blockchain impacts customer relationships by providing
accurate information and enhancing trust (Y. Cao et al. 2022; Sun et al. 2022; Yousefi et al.
2022). Twenty-two studies in the literature review investigated customer relationship practice.
24
For example, Utz et al. (2023) developed a loyalty program based on blockchain technology that
emphasizes customers' trust in service providers and resolves inconsistency in the supply chain.
Additionally, blockchain enhances customers' confidence and trust in products of their
interest by eradicating vulnerabilities in the supply chain, such as information distortions, which
in turn improves customer services (Agrawal et al. 2021; Kshetri 2021; Sundarakani et al. 2021;
Zhou et al. 2021). For example, Fosso Wamba et al. (2020) found a positive and significant
relationship between blockchain and supply chain performance. Multiple items measured the
performance; three items related to customer satisfaction: 1) satisfy customers’ requirement, 2)
ability to accelerate product for customer demand, and 3) response time to the customer. The
factor loadings of these items were sufficient for the performance: 89%, 97%, and 93%,
respectively. Similarly, Karamchandani et al. (2020) found a significant and positive relationship
for the perceived usefulness of enterprise blockchain in customer relationships.
Overall, sellers’ companies can obtain customers’ trust by providing product records,
such as provenance, and monitoring the status in the supply chain (Abdallah and Nizamuddin
2023; Biswas et al. 2023; Hu et al. 2022). For instance, Cao et al. (2021) and Garaus and
Treiblmaier (2021) found that providing information about food products via blockchain-based
platforms can influence consumers’ trust. Furthermore, Niu et al. (2022) found that consumers
would only purchase remanufactured products if transparency existed regarding the reused
materials in the remanufactured products. In other words, consumers would trust to purchase
remanufactured products if the accuracy and visibility of reused materials information is
available and accessible. Therefore, blockchain influences consumers’ trust in product quality
and purchase intention (Treiblmaier and Garaus 2023). Conversely, Dong et al. (2021) found that
25
the appearance of a devaluation effect on product quality can significantly reduce customers’
purchase intention within the adoption of blockchain.
Information Sharing
Information sharing refers to the degree of information shared among partners in the
supply chain (Jum’a et al. 2021; Kaliani Sundram et al. 2016; Li et al. 2006; Li and Lin 2006;
Tan et al. 2002). Most search results from the literature were about information sharing, with
fifty-four studies discussing this practice. The results of this practice from the literature will be
summarized as follows: how blockchain can achieve supply chain objectives and the roles that
blockchain plays at the upstream and downstream levels. One problem that supply chain partners
encounter is a lack of social and economic communications. Thus, blockchain can contribute to
solving this problem in the supply chain and achieve this objective. For example, Kshetri (2018)
and Li and Zhou (2021) provided case studies for the shipping industry in which blockchain can
solve communication issues with business partners and enable tracking of cargo movement.
Hence, blockchain can increase transparency by monitoring products and sharing information
between supply chain members (Bai et al. 2022; Chou et al. 2023).
From the upstream side, which includes supplies activities, such as supplying raw
materials for production purposes, information sharing involved between suppliers and
manufacturers. Although, trust and privacy are significant issues with business partners
regarding information sharing (Bader et al. 2021). Some studies have argued that using
blockchain for information sharing with business partners improves supply chain transparency
and enhances partners’ trust (Jensen et al. 2019; Tönnissen and Teuteberg 2020; Wang et al.
2019). However, these studies do not specify at which level business partners share information
about their transactions and to what degree privacy concerns occur among partners. Recently,
Chou et al. (2023) provided a blockchain-based framework that allows firms to collaborate and
26
share information confidentially by creating multiple private channels for each transaction (e.g.,
sales, purchase, inventory). The framework indicates that partners can privately share
information using blockchain and enhance supply chain transparency.
Conversely, the downstream includes post-production activities, such as distributing
goods to sales channels for customers. However, recalling products can cost and put companies
at high risk, such as food contamination or faulty products delivered in downstream activities
(Nandi et al. 2020; Rogerson and Parry 2020). Tracing products in the supply chain allows
companies to locate and recall specific products instead of the entire product line (Kshetri 2021).
For example, Agrawal et al. (2022) demonstrate a forward and backward chain model in the drug
supply chain. The forward model pursues monitoring products from manufacturers to customers,
whereas the backward model supports the manufacturer in recalling defective drugs. The model
benefits all supply chain members by identifying fake drugs and supporting manufacturers
towards faulty drug recalls in the supply chain.
In sum, enhancing transparency in the supply chain can be achieved by integrating
blockchain with supply chain systems (Celik et al. 2023). According to Sundarakani et al.
(2021), integrating blockchain and big data analytics can eradicate vulnerabilities in the supply
chain, such as information distortion between supply chain partners, by providing verifiable
records.
Information Quality
The information quality in the supply chain refers to accuracy, adequacy, and
trustworthiness, which supply chain members can rely on for decision-making (Jum’a et al.
2021; Kaliani Sundram et al. 2016; Li et al. 2006; Li and Lin 2006). In the supply chain context,
information quality reflects on the quality of the products by providing authentic information,
such as provenance, storage, and delivery through a decentralized platform. Thus, blockchain
27
promises accuracy and integrity of data over the supply chain and minimizes information
asymmetry (Longo et al. 2019). Nineteen studies in the literature review investigated this
practice. Kasten (2019) designed a blockchain-based system that prevents modifying information
entered into the systems about dairy products to maintain secure and high-quality products.
Similarly, other studies have also provided blockchain-based solutions for information quality
assurance in healthcare industries (Jadhav and Deshmukh 2022; J. Li et al. 2023), mining
equipment manufacturers (Wu and Zhang 2022a), and additive manufacturing in the aircraft
industry (Mandolla et al. 2019).
According to the literature on blockchain in section 2.1, blockchain can be integrated into
a collaborative system for data security. Although blockchain can be the solution to secure data
from manipulation, the technology might be inappropriate in some cases. For example, Choi and
Luo (2019) provided a case scenario for the fashion supply chain where blockchain can reduce
demand volatility by providing accurate data in the shared ledgers. Due to the high cost of
implementation, fashion firms avoid adopting the technology with respect to its sufficient impact
on data quality.
Postponement
The postponement practice refers to the strategy of forwarding supply chain operations
such as production, procurement, and distribution to another partner (Jum’a et al. 2021; Kaliani
Sundram et al. 2016; Li et al. 2006; Tan et al. 2002). I reviewed the search results of the
postponement practice; no research was found that investigated the impact of blockchain on
postponement. Although blockchain is an information processing tool that allows product
traceability in the supply chain, it may not be a suitable technology for the postponement practice
that can manage and operate tasks such as production and distribution.
28
The Conditions of Blockchain Adoption
Supply chain firms aimed to adopt blockchain for several reasons: information accuracy,
transparency, product traceability, and communication (Laforet and Bilek 2021). Adopting
blockchain for SCMPs can benefit some supply chain partners under some conditions. For
example, Niu et al. (2022) found that manufacturers would adopt blockchain to provide
information about materials used in remanufacturing products to consumers. In contrast,
suppliers do not prefer blockchain adoption unless they guarantee ignorance of consumers’ risk
aversion or at least a low degree of consumer uncertainty about the quality of the remanufactured
products. In addition, Xu et al. (2023) suggested that manufacturers should not adopt blockchain
unless the manufacturer's emission intensity is high. Industries are different in emission
intensities; for instance, textile manufacturers produce higher emission intensities than electronic
manufacturing. Although some manufacturers from both industries use recycled materials, it is
inconsistent with blockchain adoption, such as Apple.
However, blockchain may not be beneficial under some circumstances. For example,
Dong et al. (2021) found that the devaluation coefficient on product quality in online channels
influences purchase decisions with or without information sharing via blockchain. In other
words, the devaluation effect can significantly reduce customers’ purchase intention and does not
generate profit for retailers’ sales performance; thus, blockchain may not be beneficial in this
case.
Moreover, consumers' privacy is considered a critical issue in the supply chain with high
information transparency using blockchain. Due to privacy concerns, Zhang et al. (2022) found
that adopting blockchain for retailers reduces consumers' product valuation. Consumers are only
willing to pay and value retailers’ products if information transparency about product promotion
is high and the degree of consumers’ privacy concerns is low.
29
Indeed, demand volatility hurts supply chain profit due to poor data quality of ordered
quantity and forecasting (Choi and Luo 2019). Therefore, Choi and Luo (2019) explored an
analytical model with blockchain adoption in centralized and decentralized scenarios. They
found that blockchain can significantly improve data quality, reduce demand volatility, and
control overproduction in both scenarios. Hence, blockchain can positively impact the
environment and social welfare, but it harms supply chain profitability due to the high cost of
implementation. Choi and Luo (2019) also proposed a settlement to this dilemma with two
possible propositions to encourage supply chain firms to adopt blockchain. Within the
decentralized boundary, either the government sponsors firms that implemented blockchain or
the government provides an environmental taxation waiving program to those firms. Overall,
government encouragement and support for adopting blockchain increases the potential social
welfare for all supply chain members and maximizes profit (Zhong et al. 2023).
In the next section, I theorize blockchain for SCMPs to answer the third research
question: What theory or theories can assist scholars and practitioners in adopting blockchain
for SCMPs? Most studies in the literature review of this study build their findings without a
theoretical basis. Therefore, I aim to fill this gap by answering the third research question of this
study and build a theoretical model of the systematic literature review results.
Theorizing Blockchain Technologies for Supply Chain Management Practices
In the systematic literature review of this study, only thirty-seven studies applied a
theoretical lens to investigate the impact of blockchain technology in supply chain management.
Four studies were inductive research that aimed to build theory from case studies (Ali et al.
2021; Kshetri 2018, 2021; Teodorescu and Korchagina 2021). A recent study by S. Cao et
al.(2022) grounded on the strategy-as-practice theory for blockchain-based supply chain
governance and called for theory development to support blockchain for supply chain
30
management. In the following sections, 5.1 and 5.2, I discuss in detail how blockchain-based
technology can be theorized for SCMPs from the Resource-based view (RBV) and Practice-
based view (PBV) perspectives.
The Resource-based View
From the perspective of the Resource-based View (RBV) developed by (Wernerfelt
1984), RBV suggested that resources and capabilities that are valuable, rare, inimitable, and not
substitutable allow organizations to achieve competitive advantage (J. B. Barney 1991).
Resources and capabilities consider tangible assets, such as IT infrastructure, network, and
hardware, and intangible assets, such as information and vendor relationships (Wade and
Hulland 2004). Bhatt and Grover (2005) classified organizational capabilities into three
classifications: value capability, competitive capability, and dynamic capability. Teece and
Pisano (1994) suggest that firms can only sustain competitive advantage through dynamic
capability, which refers to the flexibility to integrate and re-configure the organization's
functional competencies and the ability to respond to the changing environment.
Wade and Hulland (2004) report three typologies of IS resources: inside-out, outside-in,
and spanning capability. Inside-out consists of product quality (Banker et al. 2006), IT technical
skills (Bharadwaj 2000), and information technology practices (Marchand et al. 2000). Outside-
in consists of external relationships management (Bharadwaj et al. 1999; Bharadwaj 2000)and
market responsiveness (Zaheer and Zaheer 1997). Spanning capability includes integrating
inside-out and outside-in, such as partnerships and information management practices (Wade and
Hulland 2004).
In blockchain and supply chain contexts, Treiblmaier (2018) provided a theoretical
framework of RBV for the impact of blockchain on the supply chain context. From the literature
review of this study, three studies underpinned their studies on the RBV lens. First, Sundarakani
31
et al. (2021) grounded on RBV from a case study. Their findings confirm that blockchain
strengthens the security of data records through immutability, enhancing competitive advantage.
Thus, organizations can sustain a competitive advantage by applying strategic resources such as
blockchain and leveraging supply chain visibility for market responsiveness. Second, Nandi et al.
(2020) developed a conceptual framework based on the RBV using abductive research by
collecting 126 different cases of firms in multiple industries attempting to implement blockchain
technology for their supply chain management. Third, (Paul et al. 2021) empirically examined
the impact of blockchain technology in improving the sustainable performance of the tea supply
chain using RBV and network theory.
From the IS resources typologies of Wade and Hulland (2004) explained above,
blockchain can be considered a spanning capability that integrates both inside-out and outside-in.
For example, Walmart and IBM deployed a blockchain-based collaboration platform to
strengthen the security of food products through traceability in the supply chain (Verhoeven et
al. 2018). Further, blockchain is a cryptographic technology that builds continuous lists of
blocks, transforming digital events into data records (Beck et al. 2017). Also, it is a
decentralized distributed ledger that can collect, store, and process information through
integration with other technology. It can secure its contents from modifications by using
encryption mechanisms (Davidson et al. 2016). Accordingly, blockchain can be defined as IT-
enabled technology when integrated with an existing enterprise system or IT artifacts. As
discussed in section 2.1, blockchain requires inter-organizational integration; thus, organizations
can obtain benefits from blockchain through inter-organizational relationships (Kshetri 2018).
The Practice-based View
Another perspective of RBV, the practice-based view (PBV), is related to imitable
activities or practices that are flexible to be relocated across various organizations' domains
32
(Bromiley and Rau 2014). The theoretical foundation of RBV is to explain competitive
advantage (J. Barney 1991), while PBV tends to explain firm performance (Bromiley and Rau
2014). Operational management scholars broadly have explained the performance through
practices that any firm can implement, such as supply chain collaboration (Bromiley and Rau
2016). Bromiley and Rau (2014) argued that the interactions of practices and how firms apply
and use those practices reflect on the firm performance.
Further, there should be no boundaries between practices, resources, and inter-
organizational firms (Carter et al. 2017). Since blockchain is considered inimitable based on
RBV, SCMPs are considered imitated practices and incompatible with the RBV, but it is suitable
for the PBV to explain performance.
Moreover, Carter et al. (2017) extended the PBV by including supply chain practices in
the inter-organizational environment and guided scholars to examine which practices influence
performance. Blockchain technology should positively influence SCMPs and allow practices to
provide guidelines for supply chain firms explaining the potential impact of firm performance
from the PBV perspective. According to the systematic literature review of this study, 112
studies in the literature review found that blockchain did impact SCMPs influencing supply
chain performance. Note that this research strongly supports Carter’s research (Carter et al.
2017), but the impact varies based on the type of practice and conditions fulfilled when adopting
blockchain for supply chain management. Table C1 in the appendix shows the number of studies
associated with each practice and the number of studies that discussed the conditions of
blockchain adoption for supply chain management.
33
In the next section, I develop the theoretical lens of RBV and PBV by integrating
blockchain with SCMPs. Also, I predict propositions for blockchain that influence SCMPs
following the results of the systematic literature review.
Conceptual Model and Proposition Development
From the perspective of RBV, blockchain is a spanning capability that can integrate both
inside-out and outside-in resources. These resources consist of product quality (Banker et al.
2006), technical skills (Bharadwaj 2000), information technology practices (Marchand et al.
2000), external relationships (Bharadwaj et al. 1999; Bharadwaj 2000), and market
responsiveness (Zaheer and Zaheer 1997). In contrast, SCMPs are considered imitable practices
that are flexible to be relocated across the supply chain (Carter et al. 2017). Generally, practices
tend to explain firm performance and enhance operational efficiencies (Bromiley and Rau 2014).
Bromiley and Rau (2016) argued that the interaction of applying practices across various
organizations has resulted in a useful way to explain firm performance.
In this section, a conceptual model of the RBV and PBV lenses is developed with
propositions predictions according to the systematic literature review results of the eight SCMPs
(See Figure 4). The conceptual and empirical development of the adoption of blockchain for
SCMPs from the perspectives of RBV and PBV, as outlined in section 5, has resulted in an
advantageous way to strategically analyze the adoption's value. Further, the conditions for
generating the best value from the adoption should be considered based on the adoption's
purpose, as discussed in section 4.2.
34
Figure 4. Conceptual Model of RBV and PBV
According to the literature results, blockchain-based technology impacts SCMPs and
leads to supply chain performance through the efficiency of practices, which can be achieved by
deploying blockchain technology. Supply chain performance measures varied in the literature;
for example, improving quality and increasing profit are positively associated with blockchain
integration and SCMPs. In contrast, reducing cost and demand volatility are also related to
performance, and the relationship to the integration of blockchain and SCMPs is negative in this
case. Thus, the relationship between integrating blockchain with SCMPs to the supply chain
performance can be positive or negative, depending on the performance’s measure. Based on the
literature studies, all SCMPs are associated with blockchain in the supply chain environment,
35
except for the postponement practice, in which I found no studies investigate this practice with
blockchain adoption.
Joint Product Development Proposition
According to the results of the systematic literature review of the joint product
development practice, blockchain contributes to developing new products, which enhances
supply chain efficiency and improves operational processes (Benzidia et al. 2021; Cole et al.
2019). Benzidia et al. (2021) found that blockchain-enabled integration with external entities
increases innovation. Thus, I predict the following:
P1a: blockchain directly influences join product development practice.
P1b: blockchain influences supply chain performance indirectly through joint product
development practice.
Purchasing Alliances Proposition
From the purchasing alliances literature, blockchain can securely adequate the purchasing
alliances and eliminate information leakage between supply chain partners (Nodehi et al. 2022;
Raj et al. 2022; Yadav and Prakash Singh 2022). Also, blockchain enables coordination between
suppliers and firms by tracking procured materials (Ahmad et al. 2022). Chang et al. (2021)
demonstrated a blockchain model in the supply chain and explained that the model can reduce
procurement costs and decrease the uncertainty of demand levels. A firm’s profitability relies on
high-quality procurement processes (Yadav and Prakash Singh 2022). Because blockchain can
build trust between supply chain partners for procurement processes, I predict the following:
P2a: blockchain directly influences purchasing alliances practice.
P2b: blockchain influences supply chain performance indirectly through purchasing
alliances practice.
36
Vendor-managed Inventory Proposition
Most of the systematic literature review of the Vendor-managed inventory practice
focused on the traceability of products within the supply chain to ensure quality and enhance
performance. Empirically, Kamble et al. (2020) and Yadav and Singh (2020) found that
blockchain has a positive relationship and significantly impacts inventory improvement. Also,
blockchain is associated with several factors, including political, technological, economic,
environmental, and social (Yontar 2023). Yontar (2023) categorized these factors to examine the
effectiveness of blockchain in the agricultural industry and found that blockchain can prevent
food waste, increase food security, and track product lifecycle.
Moreover, Saxena and Sarkar (2023) examined the efficiency of blockchain in tracking
real-time inventory, and the results indicated that the technology could be profitable for the
supply chain. Similarly, Ji et al. (2022) compared two manufacturers, one with blockchain and
one without blockchain. They found that blockchain can increase profit for the manufacturer
with blockchain adoption compared to the one without it. Thus, I predict the following:
P3a: blockchain directly influences vendor-managed inventory practice.
P3b: blockchain influences supply chain performance indirectly through vendor-
managed inventory.
Strategic Supplier Partnership Proposition
The strategic supplier partnership practice could lead firms to sustainable and operational
performance through technologies and communication platforms (Li et al. 2006; Tan et al. 2002).
Blockchain promotes coordination between business partners and allows information to be
shared with partners in a secure channel (Dwivedi et al. 2020; Kumar et al. 2020). Kumar et al.
(2020) designed a blockchain-based system that can eliminate manipulations of the supply chain
37
data and prevent fraud, which enhances trust between supply chain partners. Thus, I predict the
following:
P4a: blockchain directly influences strategic supplier partnership practice.
P4b: blockchain influences supply chain performance indirectly through strategic
supplier partnership practice.
Customer Relationship Proposition
Retaining customer relationships ensures the sustainability of loyalty and satisfaction (Li
et al. 2006; Tan et al. 2002). Blockchain can support firms in retaining customers’ relationships
by providing accurate information about products (Y. Cao et al. 2022; Sun et al. 2022; Yousefi et
al. 2022) and enhancing confidence in purchasing by proving provenance (Kshetri 2021;
Sundarakani et al. 2021). Empirically, Fosso Wamba et al. (2020) found that blockchain
adoption positively impacts customer satisfaction. Similarly, Karamchandani et al. (2020) found
that the perceived usefulness of blockchain influences customer relationships. Therefore, I
predict the following:
P5a: blockchain directly influences customer relationship practice.
P5b: blockchain influences supply chain performance indirectly through customer
relationship practice.
Information Sharing Proposition
In the supply chain environment, partners lack social and economic communication.
Mostly, all articles of the systematic literature review that discuss information sharing practice
concluded with the significant role of blockchain in solving communications issues. For
example, Kshetri (2018) provided eleven case studies in which integrated blockchain in the
supply chain can contribute to solving communication issues between supply chain partners.
38
Blockchain can improve operational efficiencies through information sharing (Wang et al. 2019)
and expand production (W. Liu et al. 2021). Thus, I predict the following:
P6a: blockchain directly influences information sharing practice.
P6b: blockchain influences supply chain performance indirectly through information
sharing practice.
Information Quality Proposition
According to the theoretical foundation of blockchain, information stored in the
blockchain’s ledger cannot be modified (Du et al. 2019). Blockchain retains the security and
integrity of data stored over the supply chain and eliminates information asymmetry (Longo et
al. 2019). The results of the systematic literature reviews indicate promises of blockchain to
provide accuracy and security of its contents. For example, Wang et al. (2019) found that
blockchain can improve supply chain visibility and operational efficiencies through information
security and enhances trust between supply chain partners. Thus, I predict the following:
P7a: blockchain directly influences information quality practice.
P7b: blockchain influences supply chain performance indirectly through information
quality practice.
Postponement Proposition
According to this study's systematic literature review, no articles investigated the impact
of blockchain on postponement practice. Postponement practice refers to the strategy of
forwarding supply chain operations to other business partners, such as production and
distribution (Jum’a et al. 2021; Kaliani Sundram et al. 2016; Li et al. 2006; Tan et al. 2002). The
nature of blockchain technology is an information processing tool that can process information in
the supply chain; it may not be a suitable tool for postponement practice that can manage and
39
operate production and distribution. Therefore, there are no literature articles to depend on for
the development of postponement propositions.
Implications
Implications for Practical
The lesson from the literature results translates into a few recommendations when firms
consider adopting blockchain technology for SCMPs. First, when adopting blockchain, supply
chain firms should consider their competitors who have implanted blockchain regarding their
strategy for using this technology. This allows firms to understand the market environment and
the types of customers to price their products accordingly to obtain higher profits (Ji et al. 2022).
Second, apply a confidential strategy to increase privacy settings in the supply chain. For
example, Chou et al. (2023) provided a blockchain-based framework that allows supply chain
partners to share information confidentially by having private channels for each transaction
associated with supply chain processes. Third, blockchain can be an effective solution for food
traceability to ensure freshness and quality delivered to customers. Also, it enhances the security
of pharmaceutical products and anti-counterfeiting value for medical supply chains. Fourth,
supply chain firms should collaborate with their partners to adopt blockchain not just for SCMPs
of this study but also for other management practices, such as operational and organizational
practices. According to Kumar et al. (2023), management practices influence firms to adopt
blockchain-IoT technology, leading firms to obtain a competitive advantage and enhance
performance.
However, firms need to consider the challenges and conditions of adoption discussed in
this study. Also, they need to consider the degree of transparency with their business partners
and privacy concerns.

Implications for Research
According to the search results of SCMPs, blockchain contributed to sustainable supply
chains in various sectors. First is the e-commerce sector, a blockchain-based platform called
“PRODCHAIN” that integrates production lines in the supply chain and allows information
transparency among stockholders. It improved the traceability of e-commerce products through
the platform, impacting both social and economic perspectives (Kumar et al. 2020). Second,
blockchain also involves energy supply by tracking inventory production of greenhouse gas
emissions, increasing transparency, and preventing miscalculating emissions (Diniz et al. 2021;
Teodorescu and Korchagina 2021). In response, Diniz et al. (2021) designed a blockchain-based
artifact to improve inventory processes and have more accurate carbon emission data. Third,
related-farmers products (e.g., coffee, seafood), the capability of providing products provenance
and transparency in the supply chain through blockchain alleviates sustainable issues such as
disputes and fraud (Akhtaruzzaman Khan et al. 2022; Bager et al. 2022).
In addition, during the pandemic of COVID-19, the global supply chain was exacerbated,
especially with the drug supply chain. Fluctuating demand and supply during the pandemic harm
the global supply chain, resulting in shortages for some industries. Therefore, some studies
identified the potential impact of implementing blockchain technology on the drug supply chain,
which can increase processes' efficiencies and reduce the risk of fraud information shared
between business partners (Ramirez Lopez et al. 2022). Others found that adopting blockchain-
based solutions during the pandemic is economically practical for the personal healthcare sectors
(Omar et al. 2022).
Implications for Theory
From the RBV perspective, blockchain technology can be theorized as the capability to
integrate processes and share transactions across various organizations’ domains within the
41
supply chain. In contrast, the PBV could identify when and under which conditions to adopt
blockchain for SCMPs. By focusing on specific SCMPs, the PBV will lead firms to gain the
most value from the adoption to organizations. The PBV will also provide recommendations for
decision-makers when considering the adoption of blockchain technology for SCMPs.
In addition, theorizing blockchain for SCMPs from the perspective of RBV and PBV
provides insight into the strategic plan of information systems scholars by extant analysis at the
industry or firm level. The RBV differs from the PBV by explaining competitive advantage
rather than performance as a dependent variable. Blockchain requires inter-organizational
systems, and PBV also requires inter-organizational practices to explain performance. Therefore,
integrating both theories offers new topics for research and provides a potential view of research
and theoretical implications.
In a recent research by Hanisch (2024), the author indicated that prescriptive theorizing
supports schoolers with the necessary tools to bridge the gap between real-world challenges and
actionable strategies. Thus, theorizing blockchain for SCMPs assists scholars in bridging the gap
between the practical application of blockchain in the supply chain and the research
conceptualization of SCMPs.
Discussion
The adoption of blockchain technology for SCMPs is beneficial to some firms under
specific conditions and selling formats. For example, Ma et al. (2022) found that manufacturers
are more likely to adopt blockchain only if the fixed cost associated with the use of blockchain
tends to be below a certain threshold. The threshold is related to the manufacturers’ profit, which
can be earned from two different sales formats: reselling and agency selling. In the reselling
format, the manufacturer prices their products by determining wholesale prices and recycling
costs. Subsequently, online platforms set product prices by determining the retail price and
42
marketing effort. In the agency format, the manufacturer prices their products by determining
retail prices and recycling costs. Subsequently, online platforms only determine marketing
efforts. Ma et al. (2022) demonstrated two scenarios for both selling formats, with and without
blockchain adoption. However, the profit of manufacture should be greater for both selling
formats as a condition for a manufacturer to adopt blockchain.
According to Y. Cao et al. (2022) analysis of the blockchain’s role in the agriculture
supply chain, buyers will benefit from adopting blockchain, whereas cooperative partners in the
supply chain could benefit in some cases and be worse under certain conditions. For example,
the cooperative partners are concerned with counterparty risk because the willingness to delay
payment may occur. Thus, their study showed that the blockchain could eliminate this concern
and enhance customer trust with provenance and payment challenges, reducing counterparty risk
for cooperatives and ensuring sufficiency. In contrast, the operational costs of adopting
blockchain could be worse for cooperatives, as these costs could outweigh the benefits of the
adoption.
Moreover, prior research has found that consumer sensitivity, price sensitivity, quality
sensitivity, and trust are factors that firms should consider when adopting blockchain technology.
First, manufacturers should adopt blockchain only when consumer sensitivity to blockchain is
high (Ji et al. 2022). Second, firms should adopt blockchain only when consumer sensitivity to
the product price is low and sensitivity to product quality is high (Biswas et al. 2023). However,
firms avoid blockchain adoption when the distrust level is high, and therefore, blockchain
becomes insufficient to make consumers aware of the product quality (Biswas et al. 2023).
Wang et al. (2023) analyzed manufacturing and e-commerce industries and indicated that
the e-commerce industry is more likely to adopt blockchain if the use cost of blockchain is low
43
and the anti-counterfeiting degree is high. In contrast, manufacturers use blockchain incentives to
distribute their brands in online channels and attract more customers. Furthermore, suppliers are
more likely to adopt blockchain under the following conditions: 1) if the transparency cost
coefficient is larger than a certain threshold of information reliability, 2) the supplier tolerable
cost on joining the blockchain system is less than the overall joining fee, and 3) similarly for
retailers, if the tolerable cost is less than the overall joining fee, retailers are willing to adopt the
blockchain (Zhou et al. 2022). Table 3 shows supply chain firms' potential opportunities and
conditions when adopting blockchain. This table is useful for practitioners when considering
blockchain adoption for their supply chain management.

Table 3: Potential Opportunities and Conditions of Blockchain Adoption
Opportunities
Conditions
Enhance collaboration:
Eliminate the risk of payment delay and enhance trust between
stakeholders by providing provenance information and
addressing payment challenges (Y. Cao et al. 2022).
Reduce operational cost
If the fixed cost associated with using blockchain tends to be
below a certain threshold, which is related to the
manufacturers' profit (Ma et al. 2022).
If the transparency of the cost coefficient is larger than a
certain threshold of information reliability (Zhou et al. 2022).
The supplier's tolerable cost of joining the blockchain system
is less than the overall joining fee (Zhou et al. 2022).
If the retailer's tolerable cost is less than the overall joining
fee, retailers are willing to adopt the blockchain (Zhou et al.
2022).
Improved products' quality
Firms should adopt blockchain only when consumer
sensitivity to the product price is low and sensitivity to product
quality is high (Biswas et al. 2023).
Guarantee ignorance of consumers' risk aversion or a low
degree of uncertainty about the quality of remanufactured
products (Niu et al. 2022).
Improved information
quality
Information accuracy would reduce demand volatility, but the
high cost of implementation harms profitability. Government
support for adopting blockchain increases social welfare and
supply chain profit (Choi and Luo 2019; Zhong et al. 2023).
Transparency
Consumers are only willing to purchase and value products if
transparency about product promotion is high and consumers'
privacy concerns are low (Zhang et al. 2022).
From the literature review results in this study and Table B1-Table B4 in Appendix B, I pursued
the gaps in the literature and provided future research recommendations for the information
systems researchers. First, developers should emphasize developing and evaluating solutions for
data privacy concerns when adopting blockchain. Also, researchers are still needed to examine to
what extent does blockchain provides equivalent benefits for supply chain members within the
same or different industries. Empirical research is suggested to investigate blockchain’s impact
on supply chain performance for different industries (e.g., manufacturers, services, government,
45
etc.). Table 4 illustrates the research themes, gaps, and exemplary research questions for future
research. This table is useful for scholars in future research to explore the impact of blockchain
adoption on supply chain management and its benefits to the industry. In addition, future
research may focus on the applications of blockchain-based technology impacting one or more
SCMPs.

than English can potentially bias the outcome of this study. Second, in-progress papers from the
46
search results might be published as a completed research paper in different journals and
databases, which was not in the literature search results. Future research can examine blockchain
research from additional languages and more recent results form a larger basket of journals to see
if changing environments and cultures impact the results found through this review.
Conclusion
To conclude, this study enriches our understanding of how blockchain adoption benefits
SCMPs and under which conditions blockchain influences SCMPs. I debriefed information
details on blockchain technology from the literature to examine its potential impact on the supply
chain. Several conditions must be fulfilled when considering blockchain adoption for supply
chain management. This study provides details on the seven SCMPs and their usefulness when
integrated with blockchain to improve supply chain efficiencies. Also, the study theorizes
blockchain for SCMPs from two theoretical lenses, the RBV and PBV, based on the analysis
synthesized from the literature. This research supports existing literature on the adoption of
blockchain for supply chain management, but in some circumstances, specific conditions must be
fulfilled before the adoption for better benefits.

Chapter III
Can Emergent Technologies Reduce the Bullwhip Effect? An Empirical
Analysis of the North American Public Firms
Introduction
Manufacturing and trade firms are subjected to both supply and demand volatility
(Cachon et al. 2007). Inaccurate information about inventory and demand leads to resiliency
disruptions in the supply chain. Manufacturing firms often produce more or less than demand
which causes fluctuations in inventory levels. Similarly, companies involved in the sale of goods
may not match demand (sales). This increase in inventory costs may result in the disposal of
unsold products with a fixed shelf life. Therefore, managing inventory is essential for firms to
ensure delivery of customers needs with the best quality when requested. In this paper, I refer to
the bullwhip effect as a disruption of inventory and demand in the supply chain. According to
Lee et al. (1997), the bullwhip effect refers to the phenomenon where orders to the supplier tend
to have a larger variance than sales to the buyer.(Lee et al. 1997)
In a competitive environment, firms become more dynamic and interrelated with external
opportunities and threats (J. Barney 1991). Demand variety can fluctuate by customers (Li and
Lin 2006), which results in the cause of bullwhip effect. For example, in 2020 and during the
COVID-19 pandemic, customers requested specific products at a particular time, such as toilet
paper, sanitizers, etc., which caused an unpredictable increase in demand. Integrated information
systems play a significant role in responding to customer requests and improving productivity
(Rai et al. 2006). Therefore, firms strive to keep an equilibrium between orders and demand to
ensure customer satisfaction. This can be accomplished through digitalization and integration of
business processes, which enables information-sharing capability between firms and their
48
partners in the supply chain (Li and Lin 2006). Moreover, intelligent manufacturing technology
can support automation processes in production and monitoring, enhancing production
performance (Wu et al. 2022).
In the digital revolution decades, firms started to implement IT to ensure sustainable
competitive advantage. The purpose of IT implementation in the supply chain is to coordinate
business processes between business partners. Firms in multi-industries (e.g., retailers,
manufacturers, wholesalers) tend to integrate IT to support transactional processes and share
information between business partners. For example, Electronic Data Interchange (EDI) proved
its capability to share information and improve communication between business partners
throughout the supply chain. Also, EDI supports managers in decision-making and planning,
which enhances both inbound and outbound logistics (Mukhopadhyay et al. 1995; Tallon et al.
2000).
As technology continues improving, EDI is no longer sufficient to meet the supply chain
needs of todays competitive environment. It can support data exchange among partners but
cannot engage in continuous business processes, such as tracking and monitoring products
throughout the supply chain. In response to the supply chain revolution, disruptive emerging
technologies such as blockchain, the Internet of Things (IoT), and Artificial Intelligence (AI)
have been used in the supply chain context (Bader et al. 2021; Korpela et al. 2017). The benefits
of emerging technologies can be earned when integrated with inter-organizational systems. It
promises delivery of business innovation and supports chief supply chain officers in managing
disruptions in the supply chain (IBM 2019; Wang et al. 2022). For example, firms can trace
products in the supply chain and can make a recall if a fault occurs to a specific product.
49
Technologies such as blockchain and IoT enable firms to trace products and record every
transaction within the supply chain (Kshetri and Loukoianova 2019).
Moreover, emergent technologies allow information sharing among partners in the supply
chain, enhancing managers decision-making. Firms can transform decision-making toward
decentralized rather than centralized when managers are knowledgeable about a particular
technology and its capability to support a decision (Sambamurthy and Zmud 1999).
To facilitate the modern supply chain, IBM has developed an intelligent tool called
Sterling AIS that integrates the three emergent technologies, blockchain, IoT, and AI, into an
enterprise system such as ERP (IBM 2019). The technology can facilitate and incorporate data
from heterogeneous sources. For example, IoT devices can manage business process automation
through smart contracts, in which smart contracts are blockchain-based applications (Kshetri
2017). According to Fridgen et al. (2018), combining artificial intelligence and smart contracts
adds value to the automation processes (Fridgen et al. 2018). Also, Tian (2016) has argued that
information sharing within the supply chain enhances informatization and seeks toward an
intelligence supply chain (Tian 2016). In this study, I refer to the Sterling AIS that integrates
blockchain, IoT, and AI as an emergent technologies’ integration, which can facilitate and
integrate data from heterogeneous sources and automate business processes.
The evolution of emergent technologies may add value to the supply chain and enhance
business partners relationships (Rejeb et al. 2021). The bullwhip effect is a crucial challenge for
multi-industries (Bray and Mendelson 2012; Cachon et al. 2007; Yao and Zhu 2012). Kahn et al.
(2002) and Davis and Kahn (2008) argued that IT can significantly reduce volatility and improve
inventory management, which indicates a possibility of reducing the bullwhip effect. A gap
exists between the promise of a business benefit and an actual business outcome. Therefore, this
50
study seeks to investigate the impact of this technology on the supply chain empirically.
Specifically, I address the following research question:
What is the impact of emergent technologies’ integration of blockchain, IoT, and AI on
reducing the bullwhip effect for firms?
Empirical studies that investigated the impact of the emergent technologies at the firm
level are still limited. Few studies have examined the potential of emerging technologies to
significantly transform the supply chain into a more intelligent environment (Korpela et al. 2017;
Kshetri 2018).
Next, I present transaction cost economics, theoretical background on emergent
technologies in supply chain management and the bullwhip effects, developing hypotheses and a
research model. Then I specify the methodology approach, including data collection, empirical
study, and results. Finally, I interpret the findings and discuss future research.
Theory and Literature Review
Transactional Cost Economics
Transactional cost economics (TCE) views the firm as a solution to markets problems,
such as analyzing economic activities (Gurbaxani and Whang 1991). Economizing on transaction
costs is essential for organizations to reduce bounded rationality and production costs
(Williamson 1979). Williamson (1979) specifies two types of transactions in the governance
structure (Williamson 1979). First is the bilateral governance structure, which maintains
transactions autonomously. Second, the unified governance structure refers to vertical
integration. Both transactions are organized across the firms functions. The main argument of
TCE is to govern transactions, ranging from vertical and lateral integration to transforming
transaction details between firms and markets (Shelanski and Klein 1995). The main insights of
governance are to protect the information of the involved parties and strengthen their
51
relationships in responding to any changing circumstances. Also, to maximize the value net of
both productions and governance cost through the governance structure.
Gurbaxani and Whang (1991) studied the roles of information systems in organizations
and markets. The study demonstrates key measures of organizational attributes such as firm size
and the allocation of decision-makers within the organization. The study also focused on the
relationship between IT management and organizations attributes.
From the perspective of TCE, it can facilitate understanding the relationships between
information systems and organizational structures in two various ways. First, IT employment can
reduce communication costs by enabling information availability to the decision-making
authority. Second, IT can reduce agency costs by monitoring capabilities, allowing information
to be more decentralized for decision-making (Gurbaxani and Whang 1991). In both various
ways, IT can improve the quality and speed of information processing, allowing executives to
make the right decision at the right time.
Moreover, the application of transaction cost can be used to evaluate logistics operations
and supply chain management practices. For example, suppliers may deliver faulty products or
security vulnerabilities to a business partner, and because products are not traceable, they cannot
prove a violation. In this manner, transaction cost applications can play a central role in the
coordination mechanism of the supply chain by creating electronic proximity (Grover and
Malhotra 2003). Huo (2012) empirically proved that supply chain integration is positively
associated with supply chain performance through inter-organizational systems (Huo 2012).
Emergent Technologies in Supply Chain Management
IT integration in the supply chain can lead firms to achieve potential performance
improvements by integrating business processes in the supply chain (Rai et al. 2006; Shekarian
and Ramirez 2021). For example, Huo et al. (2016) found that supply chain integration positively
52
impacts firm performance (Huo et al. 2016). It enhances the relationship between the firms’
customers and suppliers positively. Overall, systematic integration in the supply chain
significantly treats market failure, including production planning, materials management, and
distribution (Williamson 1971).
Recently, digital supply chain integration with emerging technology such as blockchain
and IoT has dramatically increased (Korpela et al. 2017; Kshetri 2018). In February 2017, the
Center for Supply Chain Studies (CSCS) launched a Drug Supply Chain Security Act and
Blockchain study.(Center of Supply Chain Studies 2018) The act required all pharmaceutical
industries to trace products throughout the supply chain by 2023. In response to the act, software
development companies deploy blockchain as an enabled solution to comply with the order of
CSCS (Lacity 2018).
Emergent technologies of the supply chain require tools to engage in the surrounding
environment. For example, blockchain enables trace of products in the supply chain and provides
details about products, such as factory and physical locations (Alshakhs et al. 2020; Engelenburg
et al. 2018). However, blockchain cannot add potential value to the supply chain without
integrating it with other technologies, such as IoT and AI. IoT sensors can transmit real-time data
into a decentralized database and increase transparency. This allows all participants to have
actual data for all transactions in the supply chain (Verhoeven et al. 2018). Also, it supports
decision-making when a recall is necessary for a specific product. For example, Toyota recalled
four million vehicles due to faulty gas pedals installed in some of the four million vehicles
(Kshetri and Loukoianova 2019). Because these gas pedals were not traceable in the supply
chain, it was impossible to identify the source and recall only the faulty products.
53
In addition, artificial intelligence (AI) can also be integrated with blockchain and IoT
devices to enhance decision-making, meaning that AI can be considered an autonomous agent
that takes information from its environment and makes decisions (Tapscott and Tapscott 2016).
In the previous example of recalling products, AI can recall products if a problem occurs during
transportation. For example, food and pharmaceutical products require a specific room
temperature during the transportation process to ensure the authenticity of the products.
Therefore, integrating the three technologies, blockchain, IoT, and AI, with an enterprise system
(e.g., ERP) is essential for firms to achieve the excellent value of an intelligent supply chain.
Bullwhip Effect
The bullwhip effect can increase the inventory cost and may require the firm to dispose
of unsold products. Lee et al. (1997) identified the causes of the bullwhip effect: demand signal
processing, rationing game, order batching, and price variation (Lee et al. 1997). Firms need to
manage the supply chain to minimize these causes and avoid the bullwhip effect.
The literature on the bullwhip effect is extensive in operational management and
economics. Studies in operation and production literature have proved that using technologies
such as MRP, ERP, and EDI supported firms in managing inventory and production in the
supply chain context (Grover and Malhotra 2003; Lee et al. 1997). Thus, a lack of managing
productions and inventories can lead firms to challenge the bullwhip effect.
Moreover, management and information systems scholars proposed possible solutions to
reduce the bullwhip effect. Bray and Mendelson (2012) found that information transmission
about demand and orders over time can reduce the bullwhip effect (Bray and Mendelson 2012).
Yao and Zhu (2012) provide evidence that the use of electronic linkage in downstream
(manufacturers industries) increases the bullwhip effect and decreases the upstream (suppliers
industries) (Yao and Zhu 2012). As a solution to the downstream sectors, they provide an
54
interaction model that shows IT can sufficiently reduce the bullwhip for downstream industries.
They referred to electronic linkage as electronic hierarchies, such as EDI and electronic markets.
Prior supply chain research examined how information sharing and electronic linkage
between partners in the supply chain reduces the bullwhip effect at the industry level (Cachon et
al. 2007; Wong et al. 2007; Yao and Zhu 2012). Bray and Mendelson (2012) investigated the
information transmission lead times before the information age (1974-1994) and after the
information age (1995-2008) in reducing the bullwhip effect at the firm level. Moreover,
reducing the volatility can improve inventory management, which can be achieved through
information technology (Davis and Kahn 2008; Kahn et al. 2002). This indicates the likelihood
that IT can significantly reduce the bullwhip effect. Thus, I specified emergent technologies as
an IT solution for supply chain firms to reduce the bullwhip effect.
Hypotheses Development
The lens of TCE focuses on examining individual transactions that are considered
essential for operational management (Garfamy 2012; Williamson 2008). Whereas supply chain
management focuses on a broader system where the focal firm can share related information on
the supply chain within and across its boundaries (Rai et al. 2006). Thus, supply chain
management aims to integrate and manage cross-functional applications. Also, enable real-time
communication of the focal firm across multiple functions and supply chain partners.
The transaction is the unit of analysis in TCE, which refers to the information exchange
about goods or services at multiple stages of business processes (Williamson 1981). Firms need
to safeguard transactions and manage the flow of goods and services by implementing a total
systems perspective (Williamson 2008) and selecting an appropriate governance structure
(Schmidt and Wagner 2019). Therefore, transaction cost applications can eliminate opportunism
55
related to the exchange relationship between business partners (Garfamy 2012), including
unethical practices such as cheating and violation of the agreement.
Information asymmetry among business partners leads to uncertainty and impacts product
quality. The decentralized supply chain can act similarly to the integrated systems with partners,
increasing information transparency and reducing opportunism (Garfamy 2012). Indeed,
transaction cost application can lead firms to pursue efficiencies or collaborate with supply chain
partners (McIvor 2009).
Furthermore, external resources increase market transactional costs for obtaining
information, such as communication costs, transporting goods, and holding inventory costs.
These costs are associated with contractual relationships with external parties, including writing
contracts and enforcing contracts’ costs. Both market transaction and external contractual costs
may cause a lack of operational efficiencies. Thus, vertical integration between business partners
allows firms to reduce transactional costs (Gurbaxani and Whang 1991).
Prior scholars found that IT can reduce external and internal coordination costs by
increasing the degree of vertical integration (Gurbaxani and Whang 1991). Currently, IT should
further contribute to strengthening the relationships between business partners through digital
communication and intelligent tools that support operational efficiencies.
The adoption of blockchain in the supply chain field ensures the validation of
transactions between business partners and expands the firm’s boundaries (Treiblmaier 2018).
Zelbst et al. (2019) found that emergent technologies such as IoT and blockchain can increase
information transparency in the supply chain. This leads to expanding the firm’s boundaries and
improving operational efficiency. The availability of information at the right time can support a
56
firm in making the right decision. Li & Lin (2006) found that trust between supply chain partners
is positively associated with both information sharing and information quality.
In addition, several studies have argued that the industry’s sectors are matters regarding
the technology’s effects on firms’ performance (Chiasson and Davidson 2005; Melville et al.
2004; Wade and Hulland 2004). For example, prior studies empirically examined technological
effects on firms performance by distinguishing industry sectors (Banker et al. 2006; Barua et al.
2004; Saldanha et al. 2013). In addition Bray and Mendelson (2012) found the bullwhip effects
varies across firms’ industries. Therefore, I developed the following hypotheses of the same
technology based on each firm’s sector:
H1a: Emergent technologies such blockchain, IoT, and AI integration use with retailers’
firms is negatively associated with the bullwhip effect ratio.
H1b: Emergent technologies such blockchain, IoT, and AI integration use with
manufacturers’ firms is negatively associated with the bullwhip effect ratio.
Adopting emergent technologies such as blockchain, IoT, and AI in the supply chain can
influence information transparency, information quality, and information sharing. All can
contribute to the firm regarding goods supply and production planning. Also, it can manage
inventory variety and demand volatility. Figure 5 illustrates the research model.

Methodology
Data
Data for this research was obtained from two sources. First, I gathered data related to
Sterling AIS implementation from the Computer Intelligence Technology database (CITDB).
According to IBM (2019), the Sterling AIS was released in October 2019. This technology is a
B2B supply chain integration suite, which expands the EDI by integrating emergent technologies
such as blockchain, IoT, and AI with Application Programming Interfaces (API) such as ERP
systems. Therefore, I extracted data for companies that implemented the Sterling AIS in 2019 as
a sample of firms that implemented the three emergent technologies.
As this technology was recently released and to the extent of its impact on the firms’
level, I restricted the sample to test for non-durable goods firms (e.g., food firms). I also separate
firms by their sector using the North American Industry classification systems NAICS codes,
focusing on manufacturers (NAICS code: 311-316 and 322-326) and retailers (NAICS codes:
445, 446, 448, and 451-454).
2
Second, I use COMPUSTAT to collect financial data for public North American firms
using ticker codes for each firm. The data originating quarterly between 2017 and 2021 allowed
to measure the bullwhip effect before and after the adoption. I only collected data for firms that
adopted the Sterling AIS in 2019 based on the CITD.
Variables
The independent variable emergent technologies integration of blockchain, IoT, and AI
was used to study the bullwhip effect. As indicated earlier, the technology was released in
2
I exempt wholesalers’ firms from analysis due to the small sample size of the wholesalers who implemented the
technology.
58
October 2019 by IBM. Thus, I treat the sample depending on time series as follows: 1) control
group (before implementation) between the first quarter of 2017 and the third quarter of 2019),
and 2) treatment group (after implementation) between the fourth quarter of 2019 and the fourth
quarter of 2021). A binary variable was used to code the independent variable in the control and
treatment samples as 0 and 1, respectively.
Data related to the dependent variable measures was collected quarterly from
COMPUSTAT from 2017 to 2021. I found missing values for five manufacturing firms and three
retailers, which were not in COMPUSTAT. After removing missing values, the total number of
manufacturers is 30 firms, and 29 firms for retailers. The dataset was unbalanced panel for both
industries; some firms did not report their financial data for certain quarters. Thus, the total
observations (by quarter) for manufacturing firms are 573 and 532 for retailers.
Prior literature argued that the industry’s sector matters regarding the technology’s
effects on firms’ performance (Chiasson and Davidson 2005; Melville et al. 2004; Wade and
Hulland 2004). Some studies have distinguished industry sectors and empirically examined
technological effects on a firm’s performance (Banker et al. 2006; Barua et al. 2004; Saldanha et
al. 2013). Thus, I measured the dependent variable depending on the firm’s industry sector.
First, fluctuating prices primarily affect retailers’ industry, which causes the bullwhip
effect (Lee et al. 1997). Promotional activity and cost shocks can contribute to increasing the
bullwhip effect. For example, if manufacturers increase prices, retailers do not place orders from
manufacturers unless their inventory level is low or products’ prices decrease.
Actual data on industry demand and orders are generally not available, however, sales
and inventory are reasonable measures for demand and orders (Cachon et al. 2007). Thus, I
followed Cachon et al. (2007) to proxy sales for retailers’ firms as an alternative measure for
59
demand and total inventory for orders. Second, the extent to which sales are conducted in
manufacturing firms is B2B. Therefore, the cost of goods sold (COGS) is a reasonable proxy for
manufacturing firms to measure demand. This measure is adopted from existing studies (Bray
and Mendelson 2012; Yao and Zhu 2012). Then I applied the variance operators for demand and
inventory across all firms in both sectors. Mathematically, the bullwhip effect is computed based
as follows:
Bullwhip effect = (inventory variance) / (demand variance)
A ratio of bullwhip effect is less than one indicates smoother operational efficiency and the
ability to satisfy customers’ needs.
Estimation and Empirical Result
Econometric Model
I estimate the firm-level bullwhip effect across industries, manufacturers, and retailers.
Because the data are panel data and the technology was adopted at a specific time (4th quarter of
2019), I used difference-in-difference estimation to distinguish the effect of the emergent
technologies on the bullwhip effect based on time, a pre-implementation and post-
implementation (See Figure 6). The difference-in-difference estimator analyzes data for two
periods and provides the difference between treatment effects and control. This technique is
known in social science research as a quasi-experimental design where the independent variable
is manipulated in multi-level treatment and control (Bhattacherjee 2012).
60
To test the hypotheses, I developed the following econometric model to measure the
effect of the independent variable in two different time series.
󰆹 󰇡 󰇢
where
󰆹 is the difference-in-difference estimator,  is the dependent variable after the
implementation (treatment effect) for firm i; and  is the dependent variable before the
implementation (control) for firm i. In other words,
󰆹 is the difference over time in the average
variance of the bullwhip effect in both time series.
To test whether
󰆹 is statistically different from zero, I applied the following regression
analysis:
 
󰆹󰇛󰇜 󰇛󰇜 
where i denotes for the focal firm, t denotes for time. is the intercept,  is a binary
variable of the independent variable equal to 1 if the time is in or after the fourth quarter of 2019
and 0 otherwise. is the difference between two groups. and are the control variables,
where is the log variance for the cost of goods sold (COGS), and is the log variance for
61
demand volatility. The variety of the firm size in both samples may have a different level of the
bullwhip effect. According to prior literature, COGS and demand volatility can be used to
control the size effect at the firm level (Gaur et al. 2005; Saldanha et al. 2013; Yao and Zhu
2012). Next, I interpret the results based on the firm’s industry.
Empirical results
To determine whether multicollinearity issues exist in the model, I tested for the variance
inflation factor (VIF) and obtained a mean tolerance value of 1.28 for retailers and 1.15 for
manufacturers. According to Wooldridge (2009), the VIF is the factor by which independent
variables are correlated with the dependent variable. A value less than 10 indicates that
multicollinearity does not exist in the model. Table 5 provides the descriptive statistics for all
variables (retailers 1st column, manufacturers 2nd column). The N represents the total periods
collected quarterly for both sectors of all firms, 532 retailers and 573 manufacturers.

Table 6 and Table 7 presents the correlation matrix among all variables for both samples
retailers and manufacturers respoectively. Also, I used the Breusch-Pagan / Cook-Weisberg test
to estimate the variance of the dependent variable from the average squared values of residuals.
The result indicates the presence of heteroscedasticity in both samples in the main model.
62
Therefore, I performed feasible generalized least squares (FGLS) estimator for the main results
(Wooldridge 2009).

For the estimation analyses, I used two procedures to test both samples. First, since there
are two groups (treatment and control) in both samples, I performed a difference-in-difference
estimator to determine the impact on the dependent variable before and after implantation.
Second, I performed FGLS estimator to estimate the model. The results indicate a similar
coefficient and significant level for all variables in both procedures. Thus, I included a
difference-in-difference estimate in the model.
63
Results are summarized in Table 8. For retailer firms (column 1), the emergent
technologies’ integration is positive and significant at the 5% level (p-value < 0.05), while the
difference-in-difference estimate is negative and significant at the 1% level (p-value < 0.01).
This indicates that the treatment effect can reduce the bullwhip effect for retailer firms (H1a
supported).
On the other hand, manufacturing firms’ results showing in Table 8 (column 2). The
emergent technologies’ integration is negative and significant at the 1% level (p-value < 0.01). In
contrast, the difference-in-difference estimate is positive and significant at the 5% level (p-value
< 0.05). This indicates that the treatment effect increases the bullwhip effect for manufacturing
firms, which counters hypothesis (H1b). As discussed in section 2.3., the causes of the bullwhip
effect are demand signal processing, rationing game, order batching, and price variation (Lee et
al. 1997). Depending on the firm's industry, fluctuating prices and promotional activities can
manipulate the bullwhip effect.
The findings regarding the variance of COGS are negative and significant at a 1% level
(p-value < 0.01) for both samples. The variance of demand volatility is positive and significant at
a 1% level (p-value < 0.01) for retailer firms, but it is not significant for manufacturing firms.

Discussion
This study demonstrates the impact of emergent technologies’ integration in reducing the
bullwhip effect at the firm level rather than in the industry. Specifically, I estimated the impact of
emergent technologies’ integration on individual firms bullwhip effects. I distinguished the data
sample depending on the firms industry: retailers and manufacturers.
The findings show that using emergent technologies for retail firms can reduce the
bullwhip effects. As discussed in section 2.3, Lee et al. (1997) identified four causes of the
bullwhip effect: demand signal processing, price variation, rationing game, and order batching
(Lee et al. 1997). The price variance fluctuates among retailers firms, mainly when firms
provide seasonal promotions. According to an economic principle, a change in one variable
causes a change in another. For example, a change in the price of products would affect a change
in the quantities for demand or supply (Mazzucato 2018). Demand signals arise from retailers
and request goods based on inventory and demand levels. Emergent technologies’ integration
65
supports retailers in managing inventory when integrated with other enterprise systems such as
ERP.
Prior literature found that electronic linkage increases the bullwhip effect for
manufacturing at the industry level (Yao and Zhu 2012). Similarly, I found that emergent
technologies’ integration increases the bullwhip effect at the firm level for manufacturing firms.
In other words, both analysis levels (industry level and firm level) have similar results regarding
the bullwhip effect for manufacturing firms. According to the causes of the bullwhip effect
above, there is information loss between manufacturers and the marketplace, resulting in false
demand or insufficient forecast from the marketplace. Using inaccurate manufacturer
information in the production schedule can increase order batching and inventory levels.
Contributions
This study provides several implications and contributions for both practical and
academic disciplines. First, I analyzed the impact of emergent technologies’ integration at the
firm level rather than the industry level in the supply chain context (Yao and Zhu 2012). I
distinguished between retailers and manufacturing firms to examine the impact of emergent
technologies’ integration based on the firms characteristics.
Most prior literature has suggested that integrated technology would improve supply
chain performance. I empirically examined this phenomenon using emergent technologies’
integration as a treatment for reducing the bullwhip effect. In particular, integrating emergent
technologies can reduce the bullwhip effect for retail firms. However, the benefit of emergent
technologies’ integration does not hold for all industries as it increases the bullwhip effect
slightly for manufacturers. Also, this study provides evidence that emergent technologies’
integration supports firms in managing demand and inventory depending on the firms industry.
66
This research suggests that integrating emergent technologies enables firms to respond quickly to
demand signals and order batching.
Limitations
This study has several limitations. First, the Sterling AIS technology, which integrated
the three emergent technologies, blockchain, IoT, and AI was released in October 2019 (IBM
2019). In the following year, the COVID-19 pandemic affected the supply chain globally, which
resulted in shortages in many supply chains. Overall, during the pandemic, uncertainty in the
supply chain disrupted the whole industries production and supply activities. It is impossible to
eliminate this impact from the current study. Second, I focused on non-durable goods firms (e.g.,
foods and pharmaceutical firms). It is possible that the impact of emergent technologies
integration could be different in durable goods firms. Also, this study has to constrained by the
available data for firms with their financial data available and accessible. Some private firms
have implemented emergent technologies, but their financial data was unavailable.
Future Research
Future research may extend this study by examining the use of emergent technologies in
private sectors and comparing the impact of this technology on publicly traded firms. Including
durable goods firms (e.g., automotive firms) to determine if the impact of emergent technologies
is similar for firms operating in different industries. Also, future research may develop a case
study to investigate the phenomenon of the emergent technologies in their natural settings. In
addition, the results of this study can be extended to test the impact of this technology after year
2022, which most supply chain firms recovered from COVID-19. The impact of this technology
could also enhance other variables of the firm such as profit or stock price.
67
Conclusion
This study examines whether integrating emerging technologies such as IoT, blockchain,
and AI into a single technology would improve supply chain performance by reducing the
bullwhip effect. The finding shows that the integration of the three emergent technologies
reduces the bullwhip effect for retailers and increases it for manufacturers. These findings extend
literature in two various ways. First, by distinguishing between retailers and manufacturing
firms. I found a different effect of the emergent technologies’ integration on the bullwhip effect
of the firm. Firms’ industry matters when examining the impact of emergent technologies in the
supply chain environment. Second, the estimation results are based on the firm level rather than
the industry level. It encourages individual firms to adopt emergent technologies intelligent for
supply chain management to improve demand and order management. This research confirms
that emergent technologies’ integration supports firms in tracking and monitoring goods in the
supply chain and their ability to respond to market demand rapidly.
68
Chapter IV
CONCLUSION
The central argument in this study is that emerging technologies have recently rapidly
increased in the supply chain environment. The decision to adopt emerging technologies for
supply chain management varies by industry and purpose. Thus, this dissertation examined
adopting emergent technologies for supply chain management practices and bullwhip effects
across two studies. The first study followed a systematic literature approach that highlighted the
adoption of blockchain technology for specific supply chain management practices and the
conditions of the adoption. I found few studies related to the involvement of blockchain in joint
product development, purchasing alliances, and strategic supplier partnership practices. Further,
significant studies show that blockchain supports vendor-managed inventory, customer
relationships, information sharing, and information quality within the supply chain. I did not find
a study related to adopting blockchain for postponement practice. However, the impact of
blockchain on supply chain management practices must fulfill certain conditions to achieve the
adoption objectives in some cases.
Furthermore, O developed a conceptual framework based on the systematic literature
review to theorize blockchain for supply chain management practices. The theoretical framework
is based on two theoretical lenses: resource-based view and practice-based view. The findings of
this study strongly support Carter’s research (Carter et al. 2017), which proposed a supply chain
practice view that eliminated the boundaries between practices and resources between firms and
performance. This study contributes to the theoretical literature on adopting blockchain for
supply chain management practices. Also, this study contributes to practitioners in the industry
by providing a comprehensive understating of each practice along with blockchain integration.
69
The systematic literature review results can also be useful for future research to cover the gaps
found in the literature.
In the second study, I empirically investigate the impact of emergent technologies
integration on reducing bullwhip effects. The emergent technologies are consistent with
integrating blockchain, IoT, and AI with enterprise systems. In the analysis, I distinguished
between retailers’ and manufacturers’ firms as industries matter in the supply chain environment.
The results indicate that emergent technologies reduce the bullwhip effects for retailers and
increase the bullwhip effects for manufacturers. However, the results support the two causes of
bullwhip effects for manufacturers identified by Lee et al. (1997): rationing game and order
batching. The other two causes affect retailers, demand signal processing and price variation, in
which emergent technologies in the sample reduce the bullwhip effect for retailers. However, the
impact of emergent technologies’ integration can be further extended to investigate their impact
on the bullwhip effects after recovery from the COVID-19 pandemic, as the sample's time series
was before and during the COVID-19 pandemic. The treatment of emergent technologies can be
different from the results, as COVID-19 affected the global supply chain, which caused
shortages in the supply chain for some products. Also, the impact of emergent technologies’
integration can be examined by its impact on other variables, such as firms’ profit or stock price,
for further benefit on firms' performance from adopting this technology.
The results of both studies guide supply chain management in improving supply chain
process efficiencies by adopting emergent technologies. Also, both studies provide opportunities
for multiple industries in the involvement of emergent technologies in their supply chain to
achieve supply chain objectives and enhance performance.
70
One of the limitations of the first study was that it did not include research written in a
language other than English, which could result from bias in the outcomes. Also, some research
studies might not appear in the literature results due to the selection of search terms and
databases. In addition, the second study has several limitations. First, the Sterling AIS, which
integrates the three emergent technologies, blockchain, IoT, and AI were released at the
beginning of the 4th quarter of 2019. This makes the treatment of this technology during COVID-
19. Consequently, I only include non-durable firms in both samples to test the impact of this
technology due to the short time of the treatment. Future research can extend the analysis to test
the impact of this technology after COVID-19 and for durable firms.
The objective of this study is to comprehensively understand the adoption of emergent
technologies in supply chain management, how supply chain firms can benefit from these
technologies, and how these technologies perform in solving supply chain issues. The approach
consists of two methodologies: systematic literature review and empirical analysis. The main
argument of this study indicates that emergent technologies are increasingly essential in supply
chain activities, which reflects more attention to scholars in IS and supply chain disciplines of
this phenomenon. I considered how emergent technology influences supply chain firms and its
benefits to improve processes and performance in some cases.
