摘要：The field of behavioral operations has produced a rich tradition of experiments in newsvendor decision-making. Our study provides a meta-analysis of 24 papers in this research area; we confirm that the pull-to-center (PtC) effect, where average order quantities in a sample lie in between average demand and optimal order quantities, is a very stable observable phenomenon across studies. However, we also show that the asymmetry in the PtC effect between high-margin and low-margin conditions vari...

摘要：This study studies discretionary healthcare services with consumption of medical goods (e.g., tests, drugs). Specifically, we focus on a setting where the service provider obtains revenue from the medical consumption, and the perceived service value improves while the amount of medical consumption decreases in the service time (e.g., due to more thorough inquiry and examination). We find that the equilibrium service and demand rates both decrease if the service provider's share of revenue from...

摘要：This paper analyzes the business-to-business transactions in which a supplier sells assortments of used products to third-party remanufacturers. The supplier offers used products in different quality conditions, called grades. We model this buyer-supplier transaction as a Stackelberg game in which the buyer chooses his optimal purchase quantity of various grades, and the supplier chooses the optimal assortment and the prices of the grades in the assortment anticipating buyer's behavior. We fir...

摘要：Research has shown that many managers and entrepreneurs tend to be optimistic and are inclined to believe that negative shocks happen to them less frequently than to others. However, there is also evidence suggesting that such optimism is often inaccurate in reality and managerial optimism can lead to the failure of a company. We develop a game-theoretic model to investigate the impact of managerial optimism on firms' performance in a competitive market. Our analysis shows that a manager's opt...

摘要：As the severity and frequency of supply chain disruptions increases due to globalization and outsourcing, companies are faced with the challenge of managing correlated disruption risks. However, correctly estimating supplier correlations is difficult and relying on incorrect estimates can be costly. Motivated by these challenges, we consider models for managing disruption risks when suppliers are ambiguously correlated. Our models are based on profit-oriented correlation structures that only r...

摘要：Activity network analysis is a widely used tool for managing project risk. Traditionally, this type of analysis is used to evaluate task criticality by assuming linear cause-and-effect phenomena, where the size of a local failure (e.g., task delay) dictates its possible global impact (e.g., project delay). Motivated by the question of whether activity networks are subject to nonlinear cause-and-effect phenomena, a computational framework is developed and applied to real-world project data to e...

摘要：This study presents an analytical framework of the product take back legislation in the context of product reuse. We characterize existing and proposed forms of E-waste legislation and compare their environmental and economic performance. Using stylized models, we analyze an OEM's decision about new and remanufactured product quantity in response to the legislative mechanism. We focus on the 2012 waste electrical and electronic equipment directive in Europe, where the policy makers intended to...

摘要：Much of the network revenue management (NRM) literature considers capacity control problems where product prices are fixed and the product availability is controlled over time. However, for industries with imperfect competition, firms typically retain some pricing power and dynamic pricing models are more realistic than capacity control models. Dynamic pricing problems are more challenging to solve; even the deterministic version is typically nonlinear. In this study, we consider a dynamic pro...

摘要：For many products, consumers need to physically experience them in order to assess their own valuations. We study how the equilibrium pricing among competing retailers depend upon assortments when consumers must search for this sort of fit information and are heterogeneous in their shopping behaviors. Specifically, we consider a market that consists of two retailers and two possible products. A consumer is either loyal to one of the retailers or is a shopper who follows a rational dynamic sear...

摘要：We consider how trade credit can coordinate a two-echelon supply chain in the presence of supplier moral hazard and costly working capital financing. While trade credit resolves moral hazard problems in the absence of working capital financing costs, we show that this is not necessarily true when financial frictions make financing trade credit costly. We then show that trade credit along with an appropriately designed reverse factoring program can restore supply chain efficiency.
