摘要：We investigate the association between continuity of care mechanisms and a patient's risk of readmission in the context of one chronic condition, heart failure. We define continuity of care as the level of consistency across patient care episodes. We dynamically measure continuity of individual referring provider; continuity of physical location, which links multiple individual providers; and continuity of Accountable Care Organization, which spans a variety of individual and institutional pro...

摘要：We study the classic assortment optimization problem in which a retailer seeks the revenue maximizing set of products to offer to each arriving customer. This study relates two variants of this assortment problem: the space constrained assortment problem, in which the retailer has a limit on the total space of the offered assortment, and the fixed cost assortment problem, in which the retailer incurs a fixed cost for each offered product. In particular, we develop an approximation scheme for t...

摘要：When designing an assortment, a fundamental trade-off exists between estimating consumer behavior more precisely and solving the corresponding optimization problem efficiently. For instance, a mixture of logit model can closely approximate any random-utility choice model; however, it is not suitable for optimization when the number of customer segments and the number of products considered are large. As many companies are using big data and marketing analytics toward microsegmenting consumers,...

摘要：Conspicuous consumption of status goods signals consumers' status and grants status value to them. In this article, we examine how firms selling status goods make vertical line extension decisions when they take consumers' status preferences into account. Analyzing an incumbent's vertical line extensions when it faces a threat of entry, we find that status preferences can make unprofitable extensions profitable. Moreover, without status preferences, an incumbent can introduce line extensions t...

摘要：The electric power industry is undergoing dramatic change driven by rapid technological transformation, concern over climate change, and evolving market structures. As a result, there is a need for new models to help the industry better utilize resources in a time of increasing uncertainty and to help government policy makers better understand the impacts of their regulatory decisions. We provide a structured review of the operations research and management science literatures to describe the ...

摘要：What do a Mongolian stir-fry restaurant and a medical lab providing home testing solutions have in common? They are both innovative services that base their success on customers controlling part of the service delivery. These providers allow service tasks to be performed by the customers as a means of shaping the overall experience and not strictly as a means of outsourcing the service. Motivated by such practices, we explore whether and how should providers allocate the control of different t...

摘要：This study considers a periodic-review joint pricing and inventory control problem for a single product, where production incurs a fixed cost plus a convex or concave variable cost. Our objective is to maximize the expected discounted profit over the entire planning horizon. We fully characterize the optimal policy for the single-period problem. As the optimal policy for the multi-period problem is too complicated to be implemented in practice, we develop well-structured heuristic policies, an...

摘要：We analyze a brand's disclosure of its supplier list to improve the suppliers' compliance with social and environmental sustainability standards. We develop a model of a buyer, a supplier, and an NGO; when a violation of the supplier occurs, the buyer and the supplier both incur penalties. Given that the disclosure influences the NGO's perception of the supplier and results in a different level of NGO scrutiny, the buyer decides whether to reveal her supplier. Our model characterizes the buyer...

摘要：The study Mitigating the U.S. Drug Shortages Through Pareto-Improving Contracts was selected as a runner-up for the Ralph Gomory Best Industry Studies Paper Award by the Industry Studies Association in 2017. The award aims at explicit recognition of the researchers' engagement with industry practitioners and demonstrate the benefits of such interactions for scholarly research. The awarded study addresses the drug shortages problem, a major challenge facing the U.S. pharmaceutical industry and ...
