Recent advancements in supply chain literature have focused on joint sustainability within the context of supplier-manufacturer relationships, particularly in scenarios in which suppliers may exhibit insufficient sustainability efforts. This study examines the intersection of joint sustainability and advanced digital technology adoption (such as Bl...

The quantity discount contract has long been one of the most frequently employed basic supply contracts. However, we must reexamine whether this contract is still effective under supply and demand disruptions that have been frequent recently. We compare three contracts: one quantity discount contract advantageous to the supplier, one quantity disco...

While technologies enable better observation and control over supply chain dynamics through visibility and real-time data analytics, the COVID-19 pandemic has intensified disruption-related challenges to supply chain network dynamics. Thus, these increased uncertainties and risks make it impossible to proactively predict the areas and sizes of surg...

This paper analyzes an incentive contract for new vaccine research and development (R&D) under pandemic situations such as COVID-19, considering the R&D contract’s adaptability to the pandemic. We study how the public sector (government) designs the adaptive R&D contract and offers it to pharmaceutical enterprises. An agency-theoretic model is empl...

Advertisers face difficult decisions when bidding on keywords in their search-engine campaigns. This paper provides guidance by empirically investigating the decisions of sponsored search advertisers, a search engine, and consumers across multiple keywords with different characteristics in a comprehensive manner. Specifically, we examine online ret...

In this paper we present a methodology, by utilizing a nonparametric multivariate cumulative sum control chart and data envelopment analysis in tandem, to evaluate and monitor distribution network performance by simultaneously considering multiple performance factors and their interrelationships. While these methods were previously applied individu...

This paper applies a Diagonal BEKK model to investigate the risk spillovers of three major cryptocurrencies to ten leading traditional currencies and two gold prices (Spot Gold and Gold Futures). The daily data used are from 7 August 2015 to 15 June 2020. The dataset is analyzed in its entirety and is also subdivided into four distinct subsets in o...

This Special Issue aims to collate the recent and original research dealing with designing and managing the reconfigurable supply chain networks in the context of digital technology and platforms, or epidemics/pandemics, or climate change, or their synergetic effects (e.g., digital platforms to manage supply chains under pandemic conditions). We st...

Intense media scrutiny and public backlash stimulate consumers to be conscientious about sustainability issues from the supply chain (SC) perspective. Accordingly, our focus in this article is on joint sustainability issues in a manufacturer–supplier relationship under a contract that possibly shares sustainability‐related costs, when there exists...

We examine a ripple effect in prehospital stroke care processes. Stroke patient care in prehospital stages is provided by emergency medical services (EMS). We divide EMS processes into three segments: dispatcher, field provider service without a patient (i.e., en route to the patient scene), and field provider service with a patient (i.e., transpor...

Researchers have studied relationship marketing in a variety of subdisciplines of marketing including service marketing, channel relationships, and business-to-business marketing. However, prior research has predominantly focused on interpersonal relationships between service providers and customers and business-to-business relationships, as oppose...

The extant literature has conceptually argued that Blockchain technology can provide both financial and operational benefits to firms in international trades. However, no studies have systematically and analytically investigated the effectiveness of Blockchain. This study introduces analytical models that consider the implementation of Blockchain t...

We consider a manufacturer’s procurement decision in a three-tier supply chain (SC) under disruption risk. The manufacturer sources components from a single first-tier supplier (FT). The FT, in turn, sources raw materials from a single second-tier supplier (ST). Suppliers in both tiers are unreliable, i.e., prone to disruption risk. Increasing SC v...

Over the past two decades, since the emergence of the triple bottom line philosophy, the relationship between environmental sustainability and corporate performance has received a lot of attention, but has generated mixed or often even contradictory results. A few recent studies have inferred that innovations are the missing link that connects the...

We study a retailer’s sourcing strategy under consumers’ stockpiling behaviour and the factors associated with the selection of an optimal strategy in multi-tier supply chains in the presence of supply disruption risk. Stockpiling behaviour occurs when consumers attempt to mitigate the negative impact of a supply shortage. We prove that those behav...

The extant sustainability literature has argued that supply chain (SC) members can gain both financial and operational benefits from a joint sustainability development (JSD) effort. However, no guidance has been provided on how SC members could collaborate on their sustainability development efforts to achieve the intended economic performance. Thi...

According to a study conducted by PwC and the Business Continuity Institute in 2013, 75% of companies experience at least one major supply chain disruption a year and majority of the disruptions were caused by supply-related problems. With an increasing emphasis on upstream risk, risk management in supplier selection has become a critical issue fac...

In recent years, strategic alliances have become key to success in sectors such as pharmaceutical and high-tech industry. Strategic partnerships between startups and big pharmaceutical companies have become more prevalent and are typically motivated by the benefits that can be obtained from complementary capabilities. These contractual relationship...

Risk management in supply chains has been receiving increased attention in the past few years. In this article, we present formulations for the strategic supply chain network design problem with dual objectives, which usually conflict with each other: minimizing cost and maximizing reliability. Quantifying the total reliability of a network design...

In recent years, access to freight transportation capacity has become a constant issue in the minds of logistics managers due to capacity shortages. In a buyer-seller relationship, reliable, timely, and cost-effective access to transportation is critical to the success of such partnerships. Given this, guaranteed capacity contracts with 3PLs may be...

Mitigating supply chain risk is a critical component of a company's overall risk management strategy. Drawing upon Contingency Theory, we posit that the appropriateness and effectiveness of risk mitigation strategies are contingent on the internal and external environments and that there is no one-size-fits-all strategy. While literature on risk ma...
