摘要：In determining their operations strategy, a firm chooses whether to be responsive or efficient. For firms competing in a market with uncertain demand and varying intensity of substitutability for the competitor's product, we characterize the responsive or efficient choice in equilibrium. To focus first on the competitive implications, we study a model where a firm can choose to be responsive at no additional fixed or marginal cost. We find that competing firms will choose the same configuratio...

摘要：We study an overbooking model for scheduling arrivals at a medical facility under no-show behavior, with patients having different no-show probabilities and different weights. The scheduler has to assign the patients to time slots in such a way that she minimizes the expected weighted sum of the patients' waiting times and the doctor's idle time and overtime. We first consider the static problem, where the set of patients to be scheduled and their characteristics are known in advance. We parti...

摘要：This article examines the effect of product development restructuring (PDR) on shareholder value. The results are based on a sample of 165 announcements made during 2002-2011.

Over a two-day period (the day of the announcement and the day preceding the announcement), the mean (median) market reaction is 1.63% (0.87%). The market reaction is generally positive regardless of the PD...

摘要：Project switching occurs when a multi-project worker shifts his/her attention from one project to another before completing the first project. In this study, we study the effects of two areas of management policy on project switching behavior, project prioritization, and work monitoring. We conduct a controlled experiment to evaluate direct and combined effects of prioritization, scheduled progress checks, and managerial progress checks on project switching behavior in a distributed, multi-pro...
