摘要：We examine the shareholder wealth effects of the adoption of the UK Modern Slavery Act 2015 (MSA). The MSA's Transparency in Supply Chains clause introduced new reporting requirements mandating certain firms to provide an annual statement outlining how they identify and mitigate modern slavery in their business and supply chain. An event study of stock price reactions of UK firms covered by the MSA to eight events associated with its adoption provides no evidence of abnormal stock returns. We ...

摘要：A substantial collection of work in operations management considers settings where a firm faces uncertain demand that depends on parameters that are ex ante unknown but can be learned by observing historical data. This work typically assumes that future demand is unaffected by the firm's learning process. However, in the new era of social media, it is increasingly the case that the information used by the firm to gauge future demand (for example, sales and stockouts or consumer feedback) is no...

摘要：Using data from 44 countries, we document a new channel through which a family business group's internal capital market supports its members. We find that groups use internal capital to incubate difficult-to-finance projects, making it feasible for them to rapidly scale up, thus facilitating their initial public offering (IPO) market access. This IPO support role is particularly valuable when groups find capital-raising through seasoned equity offerings less attractive because of control-reten...

摘要：In the school choice market, where scarce public school seats are assigned to students, a key operational issue is how to reassign seats that are vacated after an initial round of centralized assignment. Practical solutions to the reassignment problem must be simple to implement, truthful, and efficient while also alleviating costly student movement between schools. We propose and axiomatically justify a class of reassignment mechanisms, the permuted lottery deferred acceptance (PLDA) mechanis...

摘要：Interfirm contracts are plagued by opportunism arising from exchange hazards that increase the seller's gains from holdup in fixed price contracts. These exchange hazards are higher when the seller can engage in unverifiable deliberate obfuscation. Although cost-plus contracts reduce holdup losses, they suffer from cost inefficiency. Past research has underscored the importance of trust as a control instrument to mitigate losses from exchange hazards, especially social relational trust that de...

摘要：Although significant research has examined how technology can intensify racial and other outgroup biases, limited work has investigated the role information systems can play in abating them. Racial biases are particularly worrisome in healthcare, where underrepresented minorities suffer disparities in access to care, quality of care, and clinical outcomes. In this paper, we examine the role clinical decision support systems (CDSS) play in attenuating systematic biases among black patients, rel...

摘要：We examine a model of Cournot competition with congestion motivated by recent policy to allow commercial sharing of wireless spectrum that is assigned to other users such as government agencies. A key feature of such spectrum is that it is intermittently available because of the incumbent user's activity. In our model, wireless service providers (SPs) compete for a common pool of customers using their own proprietary (exclusively licensed) bands of spectrum along with access to an additional i...

摘要：We use a laboratory experiment to study the effects of disclosing the number of active participants in contests with endogenous entry. At the first stage, potential participants decide whether to enter competition, and at the second stage, entrants choose their investments. In a 2x2 design, we manipulate the size of the outside option, omega, and whether the number of entrants is disclosed between the stages. Theory predicts more entry for lower omega and the levels of entry and aggregate inve...

摘要：Providing patients with timely care from the appropriate unit involves both correct clinical evaluation of patient needs and making admission decisions to effectively manage a unit with limited capacity in the face of stochastic patient arrivals and lengths of stay. We study human decision behavior in the latter operations management task. Using behavioral models and controlled experiments in which physicians and MTurk workers manage a simulated hospital unit, we identify cognitive and environ...
