摘要：Motivated by the thriving market of online display advertising, we study a problem of allocating numerous types of goods among many agents who have concave valuations (capturing risk aversion) and heterogeneous substitution preferences across types of goods. The goal is both to provide a theory for optimal allocation of such goods, and to offer a scalable algorithm to compute the optimal allocation and the associated price vectors. Drawing on the economic concept of Pareto optimality, we devel...

摘要：We investigate retailers' dynamic pricing decisions in a stylized two-period setting with possible supply constraints and demand from both myopic and strategic consumers. We present an analytical model and then test its predictions in a behavioral experiment in which human subjects played the role of pricing managers. We find that the fraction of strategic consumers in the market systematically moderates the optimal pricing structure. When this fraction exceeds a certain threshold, the retaile...

摘要：The nature of operations executives' strategic cognition, as the antecedent to their choices about operations strategy, remains underexplored in the literature. This mixed-methods study examines executives' thinking about supply chain strategy through the lens of managerial cognition. Our qualitative study at a pharmaceutical distributor, which examined 25 executives' outlook on the future of the turbulent U.S. healthcare sector and their suggestions for adapting the company's supply chain str...

摘要：In project portfolio selection, the aim is to choose projects which are expected to offer most value and satisfy relevant risk and other constraints. In this study, we show that uncertainties about how much value the projects will offer, combined with the fact that only a subset of the proposed projects will be selected, lead to inaccurate risk estimates about the aggregate value provided by the selected project portfolio. In particular, when downside risks are measured in terms of lower perce...

摘要：This study experimentally investigates ordering behavior in the competitive newsvendor problem. We consider a duopoly market setting with two identical newsvendors selling the same perishable goods in a common market. Our experimental results show that average observed orders systematically deviate from the Nash equilibrium, and exhibit a similar pull-to-center pattern as in the classic non-competitive newsvendor experiments: average orders fall below the Nash equilibrium in the high-margin co...

摘要：Task interdependence has received a great deal of attention as a critical driver of project dynamics. This study focuses on one of these key dynamics: helping among information technology (IT) implementation project team members. We uniquely distinguish between perceptions of receiving more help than one personally provides to other team members (positive inequity), vs. giving more than one receives (negative inequity). We argue, using an equity theory frame, that members have a tendency to re...

摘要：Can peer-to-peer (P2P) marketplaces benefit traditional supply chains when consumers may experience valuation risk? P2P marketplaces can mitigate consumers' risk by allowing them to trade mismatched goods; yet, they also impose a threat to retailers and their suppliers as they compete over consumers. Further, do profit-maximizing marketplaces always extract the entire consumer surplus from the online trades? Our two-period model highlights the effects introduced by P2P marketplaces while accou...

摘要：Despite substantial financial aid from international donors for procurement of health products, stockouts of life-saving drugs related to prevalent infectious diseases are still widespread in Africa. Rigorous research to understand the underlying causes of these stockouts is lacking. To this end, we study the relationship between The Global Fund to Fight AIDS, Tuberculosis and Malaria and its grant recipients. Specifically, we leverage historical fund disbursement and drug procurement data fro...

摘要：The efforts of not-for-profit organizations (NPOs) toward enabling health care delivery in underserved communities across the globe are well-acknowledged. To date, little is known about the workings and sustenance of NPO-enabled long-term health care delivery in underserved communities, and even less about NPO-enabled surgical care delivery. Further, health care delivery in underserved communities is a context that is often characterized by primitive and poor record keeping, data scarcity and ...

摘要：Firms are increasingly outsourcing information security operations to managed security service providers (MSSPs). Cost reduction and quality (security) improvement are often mentioned as motives for outsourcing information security, and these are also the frequently cited reasons for outsourcing traditional information technology (IT) functions, such as software development and maintenance. In this study, we present a different explanation-one based on interdependent risks and competitive exte...
