摘要：Grocery retailers increasingly use acquisitions to expand their presence. Such acquisitions are risky, especially when retailers decide to subsume the acquired stores under their own banner, which can take years and demands careful planning. We show how the dynamics of consumer valuations of the old and new banner affect the traffic implications of various (spatio-temporal) rollouts, and how this can be incorporated in the conversion planning. In a store-choice model with Bayesian learning, co...

摘要：The referral priority program-an emerging business practice adopted by a growing number of technology companies that manage a waitlist of customers-enables existing customers on the waitlist to gain priority access if they successfully refer new customers to the waitlist. Unlike more commonly used referral reward programs, this novel mechanism does not offer monetary compensation to referring customers, but leverages customers' own disutility of delays to create referral incentives. Despite th...

摘要：Product expiration is an important problem in the consumer packaged goods (CPG) industry costing 1%-2% of gross retail sales and eroding industry profits substantially. It can be caused by several factors related to store operations, supply chain practices, and product characteristics. Existing methods used in the industry are inadequate to identify the causes of expiration, leading to inadequate efforts to reduce expiration. Using retail data for 768 SKUs and 10,000 stores (745,638 store-SKU-...

摘要：Using the wisdom of crowds-combining many individual judgments to obtain an aggregate estimate-can be an effective technique for improving judgment accuracy. In practice, however, accuracy is limited by the presence of correlated judgment errors, which often emerge because information is shared. To address this problem, we propose an elicitation procedure in which respondents are asked to provide both their own best judgment and an estimate of the average judgment that will be given by all oth...

摘要：We examine the effects of postcrisis financial regulation, encompassing the Dodd-Frank Act and Basel III, on market liquidity of the U.S. fixed-income market. We estimate structural breaks in a large panel of liquidity measures of corporate and Treasury bonds. Our methodology does not require a priori knowledge of the timing of breaks, can capture not only sudden jumps but also breaks in slow-moving trends, and displays excellent power properties. Against the popular claim that postcrisis regu...

摘要：The risk of patient harm resulting from medical care affects hundreds of thousands of patients and costs tens of billions of dollars every year. Advanced electronic medical records (EMRs) are expected to improve patient safety, but the evidence of their impact on patient safety is inconclusive. A key challenge to evaluating advanced EMRs' impact has been the lack of reliable patient safety data. We address this issue by analyzing a new patient safety data set from the Pennsylvania Patient Safe...
