摘要：Public health supply chains are channels through which health commodities are distributed among end clients. In developing countries, significant resource constraints hamper the effective and efficient delivery of health commodities, leading to supply chain failures such as stock-outs. While the prevalence of commodity stock-outs is well-acknowledged, there is little by way of systematic and rigorous empirical research that sheds light on the factors that drive such stock-outs in developing co...

摘要：Although spam email messages have been the primary source of cybercrime since the early Internet era, there is no quick fix to this problem. Governments have established anti-spam legislation, but surprisingly, there has been no measurement of policy impact. This study aims to fill the gap by utilizing a quasi-experimental setting in South Korea, where the anti-spam policy was substantially amended in November 2014. A significant change was in the default setting, switching from an opt-out to ...

摘要：Bundling strategies have been widely adopted by online retail platforms that use agency selling, where suppliers pay a commission fee to the platform to gain access and sell directly to consumers. We study the optimal bundling strategy for a retail platform through which two independent suppliers distribute their products. The suppliers first set their product prices, and, subsequently, the platform decides whether to offer the two products as a bundle and, if so, the price of the bundled prod...

摘要：Using data involving customer-supplier relationships and a large sample of US publicly listed firms, our study documents a negative and statistically significant relationship between economic policy uncertainty and firms' customer-base concentration. The negative relation is predominant in firms with higher inventory efficiency and those operating in competitive, high-R&D, and nondurable industries. Customer-base diversification is further shown to enhance firm performance during periods of in...

摘要：In an election campaign, candidates must decide how to optimally allocate their efforts/resources optimally among the regions of a country. As a result, the outcome of the election will depend on the players' strategies and the voters' preferences. In this work, we present a zero-sum game where two candidates decide how to invest a fixed resource in a set of regions, while considering their sizes and biases. We explore the two voting systems, the Majority System (MS) and the Electoral College ...

摘要：We study the fundamental stochastic newsvendor model that considers both demand and yield randomness. It is usually difficult in practice to describe precisely the joint demand and yield distribution, although partial statistical information and empirical data about this ambiguous distribution are often accessible. We combat the issue of distributional ambiguity by taking a data-driven distributionally robust optimization approach to hedge against all distributions that are sufficiently close ...

摘要：Do humanitarian organizations exhibit similar risk-taking behavior? This study analyzed 60 interviews from 24 case studies on four types of organizations involved in disaster response: established, expanding, extending, and emergent. By elaborating on organizational attention theory, this study investigated how organizational tasks, structures, attention, and context combine to influence organizational risk-taking behavior by different organizational types during sudden-onset disasters. Counte...

摘要：Organizations routinely introduce hitherto-unexplored interventions to improve their supply chains. Consider a principal (e.g., a firm) that implements a seemingly helpful intervention: For any fixed actions of the principal and the agents (e.g., consumers), the principal's payoff is higher in the presence of the intervention than in its absence. While one would expect such well-intentioned interventions to benefit the principal, several papers within the operations management (OM) literature ...

摘要：Given the promise of three-dimensional (3D) printing, also known as additive manufacturing, some innovative consumer goods companies have started to experiment with such a technology for on-demand production. In this study, we consider two adoption cases of 3D printing in a dual-channel (i.e., online and in-store) retail setting, and evaluate its impact on a firm's product offering, pricing, and inventory decisions. Our analysis uncovers the following effects of 3D printing. First, 3D printing...
