摘要：There exists significant hype regarding how much machine learning and incorporating social media data can improve forecast accuracy in commercial applications. To assess if the hype is warranted, we use data from the film industry in simulation experiments that contrast econometric approaches with tools from the predictive analytics literature. Further, we propose new strategies that combine elements from each literature in a bid to capture richer patterns of heterogeneity in the underlying re...

摘要：In the West, where posted prices are the norm, it is uncommon to observe consumers receive discounts below the posted price. Nevertheless, we find that when stores are asked, a discount is granted approximately 40% of the time, with a median discount percentage of 10%. Discounts are more likely to be offered by small-scale firms, for higher priced products, and for nonsale items. More generally, differences in price delegation behavior across firm types serve as an indicator that monitoring co...

摘要：Home healthcare is a rapidly growing area of the health sector in the United States. We study its role in the shift toward value-based care, as it is viewed as an avenue for achieving reductions in the cost and utilization of expensive downstream healthcare services. Using a novel data set on home healthcare visits, we examine whether and how the amount of time that a provider spends during a home health visit with a recently discharged patient impacts the patient's likelihood of being readmit...

摘要：Modern communication technologies enable efficient exchange of information but often sacrifice direct human interaction inherent in more traditional forms of communication. This raises the question of whether the lack of personal interaction induces individuals to exploit informational asymmetries. We conducted two experiments with a total of 848 subjects to examine how human versus machine interaction influences cheating for financial gain. We find that individuals cheat about three times mor...

摘要：There is an ongoing debate regarding the degree to which a forecaster's ability to draw correct inferences from market signals is real or illusory. This paper attempts to shed light on the debate by examining how personal characteristics do or do not affect forecaster success. Specifically, we investigate the role of fluid intelligence, manipulativeness, and theory of mind on forecast accuracy in experimental asset markets. We find that intelligence improves forecaster performance when market ...

摘要：Nonlinear perception of risk is integrated into models of decision under ambiguity, thereby providing a theoretical basis for behavioral analyses that involve both risk and ambiguity. The main model replaces the risk front of maxmin expected utility by rank dependent utility, and it is derived from simple, observable axioms that are not restricted to expected utility under risk. The model highlights the interaction between risk attitude and ambiguity attitude, and it is compatible with the par...

摘要：We compare non-GAAP earnings per share (EPS) in firms' annual earnings announcements and proxy statements using hand-collected data from U.S. Securities and Exchange Commission filings. We find that proxies for capital market incentives (contracting incentives) are more highly associated with firms' disclosure of non-GAAP EPS in annual earnings announcements (proxy statements). However, we find systematic differences in the properties of firms' non-GAAP earnings and exclusions depending on whe...

摘要：Prior research suggests portfolio entrepreneurs-businesspeople who run more than one firm simultaneously-launch more successful ventures than their single-business counterparts. However, their ventures are less likely to survive. In an attempt to reconcile this paradox, this paper presents a framework in which portfolio entrepreneurs' main advantage is not a superior ability to select the best business opportunities ex ante, but rather the ability to redeploy human and capital resources across...

摘要：The growing adoption of virtual queues in the service and retail industries has been greatly accelerated in recent times. In collaboration with a major ride-sharing platform, we study how the wait time information (WTI), both its initial magnitude and its subsequent progress over time, impacts customers' abandonment behavior in virtual queues. The study was conducted through a randomized field experiment that included 1,425,745 rides: one-third of the rides received a neutral WTI, one-third re...

摘要：Firms' use of special purpose acquisition companies (SPACs) to go public has increased dramatically, leading to market and regulatory debate about their use of projections. Examining SPAC mergers from 2004 through 2021, we find that 80% of firms provide projections for four years ahead on average, with approximately one-quarter of recent projections extending more than five years. For the sample of SPAC mergers with observable postmerger revenue, we find that only 35% of firms meet or beat the...
