Problem definition: This paper provides empirical evidence on the effect of the 2011 Great East Japan Earthquake (GEJE) on the financial performance of firms. Academic/practical relevance: The GEJE was characterized as the most significant disruption ever for global supply chains. In its aftermath, there was a great deal of debate about the risks and vulnerabilities of global supply chains, and there were calls to redesign and restructure supply chains. Methodology: We empirically estimate the effect of the GEJE on the stock prices of firms. Our analyses are based on a global sample of 470 firms collected from articles and announcements in the business press that identify affected firms, as well as 382 firms that are not mentioned in the business press but are in industries potentially subject to contagion or competitive effects. Results: We estimate that firms experiencing supply chain disruptions as a result of the GEJE lost on average 5.21% of their shareholder value during the one-month period after the GEJE. For Japanese firms, the effect was much more severe with an average 9.32% loss in shareholder value. Non-Japanese firms averaged a 3.73% loss in shareholder value. We also find that upstream and downstream supply chain propagation effects from the GEJE are negative, and the contagion effect on firms related to the nuclear industry is very negative. For firms in the rebuilding industries or competitors to firms affected by the GEJE, the competitive effect from the GEJE is positive. Managerial implications: The loss suffered by both Japanese firms and non-Japanese firms experiencing supply chain disruptions as a result of the GEJE is economically significant. Although the loss is more severe for firms whose operations were directly affected by the GEJE, it is also significant for firms who experienced indirect effects from their upstream and downstream supply chain partners, further confirming the importance of supply chain risk mitigation strategies.

Managerial Implications

Problem definition: This paper investigates how counterfeits influence a global supply chain and how the supply chain should effectively take anticounterfeit actions. Academic/practical relevance: The impacts of counterfeiting have been increasingly profound on global supply chains. It is critical to understand how counterfeiting impacts supply chains when supply chain members act in their own interests, and how supply chains can effectively combat counterfeiting when all the members can contribute to it. This is the first paper that offers insights into these important questions. In particular, we examine who among the supply chain members is in the best position to perform counteracting activities, how these members can cooperate in anticounterfeiting, and what economic implications the anticounterfeit actions have to the supply chain, individual firms, consumer surplus, and social welfare. Methodology: We consider a supply chain consisting of a manufacturer and a retailer, and analyze a game-theoretical framework to derive the equilibrium. Results: The manufacturer prefers to induce the retailer to combat counterfeits rather than to combat itself. Contrary to conventional wisdom, counterfeits can increase the supply chain’s profit even in the absence of network externality effects. The crux is that the manufacturer lowers wholesale price to incentivize the retailer’s counteraction and, consequently, the threat of counterfeits can mitigate double marginalization and benefit the supply chain. Managerial implications: Our results demonstrate that a sustainability risk can trigger collaborative endeavors of supply chain members and thus be advantageous to the supply chain. The findings also underscore the important role that retailers should play in anticounterfeiting. Particularly, it can be in the supply chain’s interest that the manufacturer does not execute the counteraction, either jointly with the retailer or by itself.

The Impact

Problem definition: Fast recovery from sourcing interruptions is a key objective for global supply chains and for business continuity professionals. In this paper, we study the impact of different supply chain strategies—supplier diversification and the use of long-term relationships—on the ability of a supply chain to recover from sourcing interruptions. Academic/practical relevance: Improving supply chains’ recovery ability has been an important focus area for both practitioners and academics. Collectively, available anecdotal evidence and theoretical analyses provide ambiguous recommendations driven by competing effects of different sourcing strategies. Our paper provides the first rigorous and large-scale empirical evidence relating the use of different supply chain strategies to the ability of a supply chain to recover from supply interruptions. Methodology: We develop a compound estimator of a supply chain’s recovery rate that can be constructed using limited available data (only the time series of firms’ actual sourcing behavior). Using more than two and half million import manifests, we extract firms’ maritime sourcing transactions and use this data to estimate recovery rates of different firm-category supply chains of publicly traded U.S. firms. Results: We find that supplier diversification is associated with slower recovery from sourcing interruptions, whereas the use of long-term relationships is associated with faster recovery. A one standard deviation decrease in the former is associated with a 16% faster recovery, and a like increase in the latter is associated with a 20% faster recovery. Managerial implications: Our paper brings important empirical evidence to the hitherto theoretical debate on the impact of sourcing strategies on faster recovery in supply chains. We therefore provide actionable advice on supply chain design for faster recovery.

While governance and regulation are a first step in addressing worsening working conditions in global supply chains, improving implementation is also key to reversing this trend. In this article, after examining the nature of the existing governance and implementation gaps in labour standards in global supply chains, we explore how Viet Labor, an emerging grass-roots organization, has developed practices to help close them. This involves playing brokering roles between different workers and between workers and existing governance mechanisms. We identify an initial typology of six such roles: educating, organizing, supporting, collective action, whistle-blowing and documenting. This marks a significant shift in the way action to improve labour standards along the supply chain is analysed. Our case explores how predominantly top-down approaches can be supplemented by bottom-up ones centred on workers’ agency.

Sustainability Practices

Global supply chains power 80% of world trade, but also host widespread environmental, labor, and human rights abuses in developing countries. Most scholarship focuses on some form of sanction to motivate supply chain members, but we propose that the fundamental problem is not insufficient punishment, but a lack of trust. Fickle tastes, incessant demands for lower prices, and spot market indifference force suppliers into a constant struggle for economic survival. No trust can grow in such an environment, and few sustainability practices can take meaningful root. Responding to multiple calls for scholarship in the supply chain literature, we propose a trust-building process by which supply chains can evolve from indifference and hostility to a relational partnership that produces joint investments in sustainable practices. The result is a supply chain that is more efficient, more humane, and embeds sustainability in the supply chain for the long-term.

Despite all technological advances, global supply chains are always based on the interaction of people. And wherever people interact, a kaleidoscope of ethical issues emerges. While consumer demands and concerns have undoubtedly led to an increased awareness of unethical conduct in the supply chain, contravening forces, such as the relentless pressures for low cost products and the ease by which consumers are purchasing non-deceptive counterfeits, should also not be ignored. Many retailers are now embracing ethical issues by emphasising, for example, that they take care of the production methods and working conditions pertaining to the goods they offer.

Period Model

Problem definition: We consider the effects of strategic inventory (SI) in the presence of chain-to-chain competition in a two-period model. Academic/practical relevance: Established findings suggest that SI may alleviate double marginalization and improve the efficiency of a decentralized distribution channel. However, no studies consider the role of SI under chain-to-chain competition. Methodology: We build a two-period model consisting of two competing supply chains, each with an upstream manufacturer and an exclusive retailer. The retailers compete on either price or quantity. We characterize the firms’ strategies under the concept of perfect Bayesian equilibrium. We consider cases where contracts are either observable or unobservable across supply chains. Results: (1) SI still exists under chain-to-chain competition. Retailers may carry more inventory when the competition becomes fiercer, which further intensifies the supply chain competition. (2) Different from the existing findings, SI may backfire and hurt all firms. Interestingly, firms may benefit from a higher inventory holding cost. (3) Under supply chain competition, the prisoner’s dilemma can arise if competition intensity is intermediate; in other words, manufacturers are better off without strategic inventory, and yet they cannot help allowing strategic inventory, which is the unique equilibrium. Managerial implications: Despite its appeal among firms of a single supply chain, the role of SI is altered or even reversed by chain-to-chain competition. Conventional wisdom on SI should be applied with caution.

The Impact

As the domestic businesses expand, many are making the choice to use foreign products, labor, and services to aid in their production. Global supply chains are minimizing the costs of the production process but are also creating vulnerabilities to home countries. As the global economy changes, the competitiveness between countries grows. Competitiveness can affect everything from a country’s economy to how a firm conducts international business. Addressing the need to find a method to increase the United States competitiveness in the world economy by improving the use of global supply chains would help to make domestic firms more successful in the global economy. Studying how companies position themselves abroad is important to providing insight into how to become more competitive. Worldwide companies are diversifying by moving more of their supply chain to international locations. This is providing them with many benefits such as better markets for products, lower costs, and more advanced technologies. As a result, the competitive strategy of companies is to increase production and decrease costs through the most efficient global supply chain. Maximizing the potential of domestic firms’ global supply chains is one of the most effective ways to increase U.S. competitiveness. If more big businesses in the United States are willing to participate on the global level, then the US will be able to improve their competitiveness.

A Company

As the practices of offshoring and outsourcing force the supply chain networks to keep on expanding geographically in the globalised environment, the logistics processes are becoming more exposed to risk and disruptions. Thus, modern supply chains seem to be more vulnerable than ever. It is clear that efficient logistics risk and security management emerges as an issue of pivotal importance in such competitive, demanding and stochastic environment and is thus vital for the viability and profitability of a company. In this context, this chapter focuses on a set of stochastic quantitative models that study the impact of one or more supply chain disruptions on optimal determination of single period inventory control policies. The purpose of this research is to provide a critical review of state-of-the-art methodologies to be used as a starting point for further research efforts.
