摘要:We consider a general online stochastic optimization problem with multiple resource constraints over a horizon of finite time periods. In each time period, a reward function and multiple cost functions are revealed, and the decision maker needs to specify an action from a convex and compact action set to collect the reward and consume the resources. Each cost function corresponds to the consumption of one resource. The reward function and the cost functions of each time period are drawn from a...

摘要:We explore the career consequences experienced by professional cyclists implicated in performance-enhancing drug use as well the spillover effects experienced by their teammates and managers using a data set that observes members of all teams from 2000 to 2011. Our data captures publicly known doping implications that range from informal suspicions published in the media to formal convictions by antidoping and law enforcement authorities. Our unique setting, characterized by expectations of wi...

摘要:We study how periodic uncertainty about skilled labor supply affects corporate investment using the H-1B visa program for skilled workers as an empirical setting. Exploiting cross-regional variation in H-1B labor flows based on historical immigrant enclaves, we find that firms in regions that attract more H-1B workers concentrate their investments in the quarter after uncertainty about visa access is resolved by the H-1B lottery. Consistent with a skilled labor uncertainty channel, we find tha...

摘要:The effects of private equity buyouts on employment, productivity, and job reallocation vary tremendously with macroeconomic and credit conditions, across private equity groups, and by type of buyout. We reach this conclusion by examining the most extensive database of U.S. buyouts ever compiled, encompassing thousands of buyout targets from 1980 to 2013 and millions of control firms. Employment shrinks 12% over two years after buyouts of publicly listed firms-on average, and relative to contr...

摘要:Central bank liquidity backstops and bank leverage regulation interact across financial intermediaries and states of the world. A backstop is implemented only in some states to grease the wheels of bank dealers that absorb fire sales. It also incentivizes asset managers to take on excessive redemption risk. Regulation binds in other states, in which it hamstrings market making. Because this outcome increases asset managers' fire sale costs, it reins in their risk-taking. Empirically, we confir...

摘要:Regulators have increasingly mandated firms to promptly disclose material cybersecurity incidents upon discovering these incidents. We find suggestive evidence indicating that some firms manipulate the discovery date (misreport) of a cybersecurity incident to postpone the disclosure of the incident, as evidenced by a pronounced spike in insider sales before the reported discovery date. We also find that misreporting is more prevalent among firms with weak internal control systems, when firms f...

摘要:Although clinical artificial intelligence (AI) systems can augment medical diagnosis decisions by providing competent second opinions, how to effectively integrate AI into routine diagnostic processes, such as when to present AI advice to human physicians, remains largely unexplored. Therefore, our research experimentally examines how the timing of AI advice affects diagnostic decision making using a think-aloud approach. Physicians perform medical diagnoses under three conditions: ex post adv...

摘要:We consider the placement, delivery promise, and fulfillment decisions of an online retailer. We have a set of products with given numbers of units to be placed at capacitated fulfillment centers. Once we make the placement decisions, we face demands for the products arriving from different demand regions randomly over time. In response to each demand, we pick a delivery promise to offer, which determines the probability that the demand converts into sales as well as choose a fulfillment cente...

摘要:Teletriage is a telehealth service that uses telecommunication technologies to remotely assess patients' conditions and determine their needs for medical treatment. This paper examines how teletriage affects patients' decisions to seek treatment and when healthcare providers (e.g., medical businesses, hospitals, or clinics) should launch teletriage services. Our findings reveal that teletriage can encourage more mild patients to seek treatment, discouraging more severe patients. This occurs wh...

摘要:Live-streaming advertising in e-commerce is soaring. Both Amazon and Alibaba have employed this novel marketing model to engage consumers by sequentially exhibiting different products through live-streaming videos. In this paper, we adopt a mechanism design framework to model live-streaming e-commerce as a position auction with endogenous provision of product information. We prove that finding the mechanism that simultaneously optimizes position allocation and information provision is NP-hard....
