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：We study an off-policy contextual pricing problem in which the seller has access to samples of prices that customers were previously offered, whether they purchased at that price, and auxiliary features describing the customer and/or item being sold. This is in contrast to the well-studied setting in which samples of the customer's valuation (willingness to pay) are observed. In our setting, the observed data are influenced by the previous pricing policy, and we do not know how customers would...

摘要：I study depositor behavior in panic-driven bank runs using an LLM-based survey simulation. I build a representative population of synthetic agents by assigning demographic attributes, expose them to a viral panic post, and randomize bank communication interventions. I validate model responses against human benchmarks and then generate systematic message variants that vary tone, strength, and content within the validated design space. I then include the estimated withdrawal propensities into a ...

摘要：We study firms' incentives to adopt a tracking technology to collect personal data that enable personalized pricing in an online market where some consumers have innate desires for privacy. In a model where two differentiated goods are sold under two different market structures (monopoly and duopoly), we find that the presence of these privacy-sensitive consumers alters the firms' incentive to adopt personalized pricing. In particular, no firm uses personalized pricing in equilibrium if the pr...

摘要：What happens if we train a new large language model (LLM) using data at least partially generated by other LLMs? The explosive success of LLMs means that content online will increasingly be generated by LLMs rather than humans, which inevitably enters the training data sets of next-generation LLMs. In this paper, we study the implications of such regurgitative training on LLM performance. Starting with the machine translation task (a representative language task with well-established evaluatio...

摘要：As ride-sharing becomes an integral part of ride-hailing platforms, understanding its operational and economic implications is crucial. Although shared rides can improve system efficiency and reduce congestion, they also introduce trade-offs, such as longer wait times and rider discomfort. In this paper, we develop a game-theoretic queueing model to examine how a platform operating with one of three objectives, i.e., volume, revenue, or social welfare maximization, sets prices for solo and sha...

摘要：The U.S. Security and Exchange Commission's (SEC's) Division of Enforcement is frequently criticized for its ineffective oversight, and certain vocal critics attribute this to a lack of financial experience within the SEC. Using novel hand-collected data on SEC regional directors, I find that most of these senior SEC officials lack practical financial experience. I then use a staggered difference-in-differences research design and find that directors with financial experience open 62% more inv...

摘要：U.S. health system reform simultaneously promotes alternative payment models (APMs) and integrated provider organizations, where integration is assumed to better enable providers to coordinate and manage the risks introduced by APMs. While the interaction of these two changes has implications for both APM design and regulation of provider integration, it is not well studied. In this paper, we offer empirical evidence on the role of horizontal and vertical integration of orthopedic surgeons in ...

摘要：This paper reports a meta-analysis of 86 studies of the two parameters of quasihyperbolic (13-6) discounting, the dominant model of self-control failures in behavioral economics. The central tenet of the model is that decision makers have a present bias, 13, for immediate rewards, on top of standard exponential discounting of the future, 6. After correcting for selective reporting, we obtain a meta-analytic estimate of 13 for money of 0.938, with 95% confidence interval [0.905, 0.972]. For non...
