摘要：In practice, lead time demand (LTD) can be skewed, multi-modal or highly variable, and these factors compromise the validity of typical approaches used for setting safety stock levels. Motivated by encountering this problem at our industry partner, we develop an approach for setting safety stock levels using the bootstrap, a widely used statistical procedure. Existing bootstrap approaches for inventory management either operate directly on observed LTD or assume deterministic lead times, permi...

摘要：In many settings, consumer surplus directly impacts a firm or organization's objective, and the profit-only objective becomes inadequate. Our paper is the first to consider the dual objective of profit and consumer surplus in multi-product pricing under the multinomial logit demand, where the prices are continuously set. We define a firm's marginal consumer surplus as its marginal contribution to the expected customer utility transformed into monetary unit. Although the profit is concave in th...

摘要：This study examines long-term care (LTC) discharge planning among older delayed discharge patients. While awaiting placements in alternate care such as LTC, these patients occupy hospital beds despite not requiring an intensive level of care. This study proposes a novel discharge decision model based on the Markov decision process (MDP) framework, which incorporates predictions regarding the patients' health trajectory and the associated hospital costs. Our machine learning (ML)-based predicti...

摘要：Many individuals have strong preferences regarding COVID-19 vaccines and would like to choose the vaccine they get. This practice, known as vaccine shopping, presents unique challenges to timely vaccine rollout: On the one hand, people may not get vaccinated if they are unable to receive their preferred vaccine, and on the other hand, a policy maker is inclined to distribute vaccines in a brand agnostic fashion to avoid wastage. We study whether a policy maker should allow individuals to choos...

摘要：The choice of market mechanism is key to success for any online marketplace. In recent years, as peer-to-peer (P2P) lending has seen phenomenal growth, leading P2P lending platforms have used various market mechanisms and, in some cases, even switched from one mechanism to another, chasing higher market share and overall growth. While Prosper.com, a leading P2P lending platform, has switched from the auction lending model to a fixed price lending model, recent studies show that overall social ...

摘要：Mergers and acquisitions (M&As) by first-tier suppliers, referred to as the supply base, are dynamic and drastic changes in supply chain structure and relationships that affect focal firm performance. In particular, the impact of M&As in a supply base depends on the concentration and differentiation of the supply base, which affects power-dependence relationships in the supply chain. This study examines the effect of supply base M&As on focal firms' cost of goods sold (COGS). In addition, this...

摘要：Up to 20% of all business-to-consumer deliveries fail on the first attempt. Failed deliveries not only carry cost implications but also incur damage to retailers' brand reputation. Despite its economic significance, research has paid little attention to delivery attempt as an operational outcome or seldom accounted for its effects in routing models. This is partly due to the many factors that can influence delivery outcomes. We address this knowledge gap by first demonstrating that failed deli...

摘要：What makes a technology valuable? Characterizing the value as the degree of impact on subsequent technology development and focusing on the rareness as a composite measure of novelty and conventionality representing the relative position of a technology in a technology space, we advance a theory on the relationship between the rareness and value of a technology as well as the moderating role of search basis in shaping the relationship. We build our theory exploiting the fundamental trade-off b...

摘要：Supply diversification and pricing are two common mechanisms for dealing with supply yield uncertainty. This paper characterizes a firm's pricing and sourcing decisions under supply yield uncertainty, and studies the interplay between the two mechanisms. We compare the optimal sourcing decisions under two distinct pricing schemes: (1) ex ante pricing-the firm simultaneously makes the sales price and sourcing decisions before production takes place; (2) responsive pricing-the pricing decision i...

摘要：When considering a purchase, consumers often augment their private information about a product with anonymous online social information (reviews, etc.). We examine the impact on firm strategy of how consumers weight these two information sources-private and social-in their purchase decisions. An increase in weight on private information always results in higher prices at the interior equilibrium. However, the effects on profits, consumer, and total surplus are nonmonotonic: all increasing with...
