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：This paper examines the relationship between price-fixing cartels and firm innovation using a data set encompassing all 461 cartel cases and 1,818 firms identified in the United States in the years 1975-2016. A difference-in-differences estimation reveals a positive relationship between collusion and innovation. Colluding firms exhibited increases of 28% in patent filings, 20% in top-quality patents, and 16% in research and development investment. Innovation breadth also expanded by 16%, sugge...

摘要：In this study, we leverage the transformation of a performance management system that shifts from only providing a performance rating to also providing an explicit assessment of potential. Although performance measures enable organizations to evaluate an employee's past performance, they provide limited information regarding the employee's potential to perform in a prospective job that requires a different skill set. Consequently, firms are gradually moving toward the incorporation of explicit...

摘要：Can digital payments help reduce extreme hunger? Humanitarian needs are at their highest since 1945, aid budgets are falling behind, and hunger is concentrating in fragile states where repression and aid diversion present major obstacles. In such contexts, partnering directly with governments is often neither feasible nor desirable, making private digital payment platforms a potentially useful means of delivering assistance. We experimentally evaluated digital payments to extremely poor, femal...

摘要：When home prices threaten to decline, large mortgage investors can benefit from fostering new lending that boosts demand. We ask whether this benefit contributed to the growth in acquisitions of risky mortgages by the Government Sponsored Enterprises (GSEs) in the first half of 2007. We find that it helps explain the variation of this growth across regions, as well as regional house price and credit changes. The growth predicted by this benefit is on top of the acquisition growth caused by the...

摘要：This study examines the information content of textual disclosures in firms' earnings announcements. Using a large language model (LLM) to capture information in both words and word context, I show that the news in earnings press releases (i) explains three times more variation in short-window stock returns than a host of textual measures based on dictionary and non-LLM machine learning methods; (ii) doubles the R2 of an array of financial statement surprises, modeled with conventional regress...
