摘要：Quality disclosures regarding medical outcomes such as patient mortality are common healthcare policy instruments. Mixed evidence exists on whether quality disclosures improve outcomes for disclosed ailments. Moreover, disclosure policies can generate spillovers and impact ailments not targeted by the policy. We examine the effects of quality disclosure regulation on mortality improvements in disclosed and nondisclosed ailments. We use patient records for California hospitals for 1995-2014 and...

摘要：Choosing job applicants to hire in online labor markets is hard. To identify the best applicant at hand, employers need to assess a heterogeneous population. Recommender systems can provide targeted job-applicant recommendations that help employers make better-informed and faster hiring choices. However, existing recommenders that rely on multiple user evaluations per recommended item (e.g., collaborative filtering) experience structural limitations in recommending job applicants: Because each...

摘要：In this paper, we study a family of sales-based rebate mechanisms as an effective tool to implement price discrimination across a population of buyers with correlated heterogeneous valuations on indivisible goods and services. In order to implement such sales-based rebate mechanisms, the seller charges each buyer a fixed price at the time of purchase contingent on a rebate that is a function of the ex post sales volume to be realized at the end of the sales period. The seller declares both a p...

摘要：We use eBay data to investigate how within-U.S. trade is influenced by differences in socioeconomic characteristics. States' similarity in cultural characteristics (ethnicity, religious affiliations, and political behavior) predicts online trade; cultural similarity similarly predicts trade within product categories. The culture-trade relationship is stronger for transactions with sellers who lack extensive reputations or certification, suggesting that consumers infer seller trustworthiness fr...

摘要：We investigate a data-driven multiperiod inventory replenishment problem with uncertain demand and vendor lead time (VLT) with accessibility to a large quantity of historical data. Different from the traditional two-step predict-then-optimize (PTO) solution framework, we propose a one-step end-to-end (E2E) framework that uses deep learning models to output the suggested replenishment amount directly from input features without any intermediate step. The E2E model is trained to capture the beha...

摘要：We derive a firm's debt issuance policy when managers have an informational advantage over creditors and face debt restructuring costs. In our model, regardless of how poor their private signal is, managers of firms that can access the credit market avoid default by issuing new debt to service existing debt. Therefore, only bonds of firms that have exhausted their ability to borrow are subject to jump-to-default risk because of incomplete information and, in turn, command a jump-to-default ris...

摘要：We study healthcare operations of emergency departments (EDs) by examining the practice styles and skills of ED physicians. Our data include all residents of Montreal, Canada, with an initial ED visit in Montreal during a nine-month period. For each visit, our data record the initial treating hospital, ED physician, ED billed expenditures, and all interactions with the health system within the subsequent 90 days. Physicians in Montreal rotate across shifts between simple and difficult cases, i...

摘要：Health systems are placing increasing emphasis on improving the design and operation of clinical trials with the aim of making the health technology adoption process more value-based. We present a model of a value-based, two-armed clinical trial in which both the recruitment rate and trial length are optimized. The model is value-based because it balances the cost of the trial with the expected benefit it generates for patients, valued by the relative health benefits and costs of the technolog...

摘要：Telemedicine is increasingly used across the developing world to expand access to healthcare, to improve outcomes, and to reduce costs. One common model is that of telemedicine centers, which are small primary care facilities run by midlevel (nonphysician) providers who conduct a preliminary examination and then facilitate a telemedicine visit with a remote physician in real time. However, the impact of this channel of care delivery-particularly on existing physical healthcare-delivery channel...

摘要：This paper analyzes how the degree of task-related team diversity influences the team outcome. The focus is on a novel benefit of team diversity that does not depend on complementary skills or mutual learning. We consider a multiagent setting where the employer makes use of career competition to motivate the team. Our analysis reveals incentive effects that do not exist in the well-studied case of teams of size 2. In teams with more than two members, diversity may have a positive effect on the...
