摘要：Multi-armed bandit has been well known for its efficiency in online decisionmaking in terms of minimizing the loss of the participants' welfare during experiments (i.e., the regret). In clinical trials and many other scenarios, the statistical power of inferring the treatment effects (i.e., the gaps between the mean outcomes of different arms) is also crucial. Nevertheless, minimizing the regret entails harming the statistical power of estimating the treatment effect because the observations f...

摘要：The Securities and Exchange Commission (SEC) permits managers to request the exclusion of shareholder-initiated proposals. I construct a novel data set of excluded and withdrawn proposals from the SEC's responses to managers' requests. An examination of announcement returns to withdrawal and exclusion decisions demonstrates that SEC-challenged proposals are value destroying. I find that special interest investors pursuing self-serving agendas and retail investors advocating for one-size-fits-a...

摘要：U.S. generally accepted accounting principles (GAAP) allows banks to offset derivative assets against derivative liabilities with the same counterparty and report only the net amount on the balance sheet. Derivative offsetting under international financial reporting standards (IFRS) is much more restrictive, resulting in the single largest differ-ence in balance sheet presentation between U.S. GAAP and IFRS. Two important factors dominate the standard-setting discussion on this issue: (1) whet...

摘要：We present a nonparametric method to recover a bound on ex ante dispersion of beliefs (DBB) from asset prices with minimal assumptions. DBB constrains the dispersion among all possible distributions in an economy, consistent with observed prices and subject to a good -deal bound. In model -based economies, DBB effectively tracks belief heterogeneity and serves as a diagnostic tool for evaluating model calibrations. Empirically, DBB relates to common proxies of belief dispersion, offering a rea...

摘要：Cybersecurity breaches pose a substantial concern in the digital era. We investigate how customers respond to multiple unexpected data breaches of their information in India. Difference -in -differences estimates show that digital payments declined by 9% relative to cash payments immediately after an unexpected data breach in a food delivery platform, but the gap disappeared three months later. Customer entry and exit also exhibit weak, short-lived changes. Additional analyses on bank and onli...

摘要：To stay competitive, firms regularly invest in innovation by supporting internal capital projects (funded and executed in-house) that explore new products and operational improvements. Each year, in a highly competitive process, managers from different functional units of the firm submit proposals (that include estimated costs and benefits) for such projects. Managers, because of their domain knowledge and expertise, are naturally better informed about the costs and benefits of their respectiv...

摘要：We study a variation of the classical Pandora's problem in which a decision maker (DM) sequentially explores alternatives from a given set and learns their values while trying to acquire the best alternative. The variations in the model we study are (i) alternatives randomly become unavailable during exploration and (ii) the DM's ability to acquire a remaining alternative is uncertain and depends on a chosen offer price. Such acquisition uncertainties arise in many applications, including hous...

摘要：Using data from a prominent online platform for launching new digital products, we document that sampling bias-defined as the difference between a startup's target customer base and the actual sample on which early beta tests are conducted- has a systematic and persistent impact on the venture's success. Specifically, we show that products with a female-focused target market launching on a typical day, when nine in 10 users on this platform are men, experience 45% less growth a year after laun...

摘要：Motivated by our collaboration with Anheuser-Busch InBev (AB InBev), a consumer packaged goods (CPG) company, we consider the problem of forecasting sales under the coronavirus disease 2019 (COVID-19) pandemic. Our approach combines non parametric regression, game theory, and pandemic modeling to develop a data-driven competitive online nonparametric regression method. Specifically, the method takes the future COVID-19 case estimates, which can be simulated via the susceptible-infectious-remov...
