摘要：In several applications of real-time matching of demand to supply in online marketplaces, the platform allows for some latency to batch the demand and improve the efficiency of the resulting matching. Motivated by these applications, we study the optimal trade-off between batching and inefficiency in the context of designing robust online allocations. As our base model, we consider K-stage variants of the classic vertexweighted bipartite b-matching in the adversarial setting, where online vert...

摘要：In this study, we provide evidence on the effects of state tax whistleblower laws. We exploit a novel 2010 amendment to New York's False Claims Acts (FCA) that explicitly extended whistleblower incentives to corporate income tax whistleblowers. We identify treated firms (firms exposed to New York's FCA) using establishment-level data and descriptive analyses. Using a sample of firms exposed to New York and neighboring states, we find evidence that New York's FCA reduced state tax avoidance. In...

摘要：Cryptocurrencies have prompted a shift away from classic security attacks toward ransomware-based extortion. To better understand the impact of cryptocurrencies on the cybersecurity landscape, we conduct a comparative analysis of cybersecurity metrics prior to and after the adoption of cryptocurrency using a series of connected software-use models in the presence of security externalities. In this framework, we endogenize the actions of both heterogeneous consumers and attackers, with entry of...

摘要：We study the data-integrated newsvendor problem in which the random demand depends on a set of covariates. Observing from the solutions analyzed in the existing studies, we identify the equivariant class of operational statistics (i.e., the mapping from the demand and covariate data to the inventory decision) to develop the operational data analytics (ODA) framework for the contextual newsvendor problem. The equivariant property is intuitively appealing, and it is justified by the fact that, r...

摘要：Prior auditor shopping literature examines managers' attempts to opportunistically underreport negative news by finding auditors who will allow them to avoid negative audit opinions or underreport goodwill impairments or financial misstatements. We advance this literature by examining management attempts to opportunistically report positive news, as captured by income-increasing changes in accounting estimates. Adapting a previous framework, we find that, ex ante, managers are more (less) like...

摘要：Online retail settings often present shoppers with large, complex choice sets where they need to quickly and dynamically weigh the benefits and costs of search within each web page. We build a model of information search within a web page using eye- tracking data collected during two incentive-compatible online shopping experiments, in which participants browsed the websites of two different clothing retailers (Experiments 1 and 2), as well as previously reported data from a laboratory experim...

摘要：Satellite images of the parking lots of U.S. retail firms provide information about the firms' future earnings, and the limited access to these images produces information asymmetry between sophisticated and unsophisticated investors. We construct a cloudbased information risk (CIR) measure to capture this satellite information risk and investigate its asset pricing performance. We find that CIR positively predicts future stock returns of retail firms in the cross-section and that the predicta...

摘要：Health technology assessments often inform decisions made by public payers, such as the UK's National Health Service, as they negotiate the pricing of companies' new health technologies. A common assessment mechanism compares the incremental costeffectiveness ratio (ICER) of the new health technology, relative to a standard of care, to maximum threshold on the cost per quality-adjusted life year. In much research and practice, these assessments may not distinguish between cost-per-patient and ...

摘要：We consider a class of online decision-making problems with exchangeable actions, where in each period a controller is presented an input type drawn from some stochastic arrival process. The controller must choose an action, and the final objective depends only on the aggregate type-action counts. Such a framework encapsulates many online stochastic variants of common optimization problems with knapsack, bin packing, and generalized assignment as canonical examples. In such settings, we study ...

摘要：The secretary problem is probably the most well -studied optimal stopping problem with many applications in economics and management. In the secretary problem, a decision maker faces an unknown sequence of values, revealed successively, and has to make irrevocable take -it -or -leave -it decisions. Her goal is to select the maximum value in the sequence. Although in the classic secretary problem the values of upcoming elements are entirely unknown, in many realistic situations, the decision ma...
