摘要：In this study, we examine the hospital's ability to admit patients from its emergency department. From a medical perspective, the number of patients being admitted should depend solely on the patients' clinical conditions. Using a large-scale econometric study that includes detailed operational and clinical data on all cardiac patient encounters from a set of 128 hospitals over a period of four years, we show that this is not the case. In particular, we find that independent of their medical c...

摘要：In scheduling medical residents, the objective is often to maximize resident satisfaction across the space of feasible schedules, relative to the many hard constraints that ensure appropriate patient coverage, adequate training opportunities, etc. A common metric of resident satisfaction is the number of time-off requests that are granted. Simply maximizing this total, however, may lead to undesirable schedules since some requests have higher priority than others. For example, it might be bett...

摘要：This study explores how suppliers adjust their relation-specific investments (RSI) in response to the different risk-taking incentives provided by the customer firm to its CEO, during normal and transition periods. We investigate this relation using 17,553 customer-supplier transactions over the 1993-2013 period. We find strong evidence consistent with the risk-taking argument. Specifically, we find that an increase in the risk-taking incentives of customer CEOs leads to a decline in suppliers...

摘要：Because of environmental and economic reasons, an increasing number of original equipment manufacturers (OEMs) nowadays sell both new and remanufactured products. When both products are available, customers will buy the one that gives them a higher (and non-negative) utility. Thus, if the firm does not price the products properly, then product cannibalization may arise and its revenue may be adversely impacted. In this paper, we study the pricing problem of a firm that sells both new and reman...

摘要：The recent proliferation of media reports on substances of concern has increased consumer fears, sparked scientific debate, and highlighted the need for stronger chemical regulations. When a substance of concern is identified (e.g., bisphenol-A (BPA) in reusable water bottles), manufacturers face difficult trade-offs in deciding whether to proactively replace the substance in their products or to defer replacement and wait to see if regulation occurs. In this study, we examine when opportuniti...

摘要：We consider a transportation station, where customers arrive according to a Poisson process, observe the delay information and the fee imposed by the administrator and decide whether to use the facility or not. A transportation facility visits the station according to a renewal process and serves all present customers at each visit. We assume that every customer maximizes her individual expected utility and the administrator is a profit maximizer. We model this situation as a two-stage game am...

摘要：A mass customization strategy enables a firm to match its product designs to unique consumer tastes. In a classic horizontal product-differentiation framework, a consumer's utility is a decreasing function of the distance between their ideal taste and the taste defined by the most closely aligned product the firm offers. A consumer thus considers the taste mismatch associated with their purchased product, but otherwise the positioning of the firm's product portfolio (or, brand image) is immate...

摘要：We study inventory optimization for locally controlled, continuous-review distribution systems with stochastic customer demands. Each node follows a base-stock policy and a first-come, first-served allocation policy. We develop two heuristics, the recursive optimization (RO) heuristic and the decomposition-aggregation (DA) heuristic, to approximate the optimal base-stock levels of all the locations in the system. The RO heuristic applies a bottom-up approach that sequentially solves single-var...

摘要：Inventory displayed on the retail sales floor not only performs the classical supply function but also plays a role in affecting consumers' buying behavior and hence the total demand. Empirical evidence from the retail industry shows that for some types of products, higher levels of on-shelf inventory have a demand-increasing effect (billboard effect) while for some other types of products, higher levels of on-shelf inventory have a demand-decreasing effect (scarcity effect). This suggests tha...
