摘要：Service systems are often stochastic and preplanned by appointments, yet implementations of their appointment systems are prevalently deterministic. At the planning stage of healthcare services, for example, customer punctuality and service durations are often assumed equal their means-and this gap, between planned and reality, motivated our research. Specifically, we consider appointment scheduling and sequencing under a time-varying number of servers, in a data-rich environment where service...

摘要：We develop a theory that shows signaling a firm's fundamental quality (e.g., its operational capabilities) to lenders through inventory transactions to be more efficient-it leads to less costly operational distortions-than signaling through loan requests, and we characterize how the efficiency gains depend on firm operational characteristics, such as operating costs, market size, and inventory salvage value. Signaling through inventory being only tenable when inventory transactions are verifia...

摘要：Hospital managers struggle with the day-to-day variability in patient admissions to different clinical services, each of which typically has a fixed allocation of hospital beds. In response, many hospitals engage in capacity pooling by assigning patients from a service whose designated beds are fully occupied to an available bed in a unit designated for a different service. This off-service placement occurs frequently, yet its impact on patient and operational measures has not been rigorously ...

摘要：Corporations often transact in their own mispriced stock. This activity, known as equity market timing, can generate substantial profits and increase the long-term stock price. We challenge a closely related popular view that market timing always benefits firm shareholders. Opportunistic financing maneuvers by a firm can negatively affect its un-informed stock owners because of adverse selection and the change in the firm's short-term price, whereas the long-term returns do not accumulate to d...

摘要：Because many key career events, such as examinations and interviews, involve competition and stress, gender differences in response to these factors could help to explain the labor market gender gap. In a laboratory experiment, we manipulate psychosocial stress using the Trier Social Stress Test and confirm that this is effective by measuring salivary cortisol level and heart rate. Subjects perform in a real-effort task under both tournament and piece-rate incentives, and we elicit willingness...

摘要：Safety alerts are announcements made by health regulators warning patients and doctors about new drug-related side effects. However, not all safety alerts are equally effective. We provide evidence that the day of the week on which the safety alerts are announced explains differences in safety alert impact. Specifically, we show that safety alerts announced on Fridays are less broadly diffused: they are shared 34% less on social media, mentioned in 23% to 66% fewer news articles, and are 12% t...

摘要：This paper studies how the ease of repossessing collateral in bankruptcy affects corporate leasing policy. Using plausibly exogenous variation of the ability to repossess assets generated by state antirecharacterization laws, I find that the antirecharacterization laws, which make collateral repossession easier for secured lending, reduces corporate leasing. Consistent with the argument that only financially constrained firms value additional debt capacity because of the increased ability to r...

摘要：We investigate a situation where a firm employing a sales agent faces moral hazard with respect to prospecting effort and the threat of collusion between agent and customer. We show that the firm should offer more pricing authority to the agent the more severe the moral hazard problem, although doing so further expands the agent's discretion. Nevertheless, restricting the agent's pricing authority such that he cannot sell to low-valuation customers is typically optimal to prevent collusion. We...

摘要：Retailers colocate with rivals to take advantage of economies of agglomeration even though colocation implies greater competition. Using data on all new car transactions registered in Ohio from 2007 to 2014, we estimate a structural model of consumer search for spatially differentiated products that explicitly captures the agglomeration and competition effects of retail colocation. Search frictions generate an average of $333 per car in dealer markups. Agglomeration implies that dealer closure...

摘要：We examine the response of prosocial employees and boards of directors to corporate misconduct. We develop several proxies for the presence of prosocial employees and directors based on the density of social networks and social capital in the county of the firms' headquarters and companies' relevant corporate social responsibility ratings. We document that proxies for prosocial employees and directors are associated with an increase in whistle blowing and forced chief executive officer turnove...
