摘要：We study whether and how the availability of incremental time associated with retirement and unemployment affects the types of products households buy. For this, we develop a new theoretical model of the composition and size of the grocery shopping basket subject to money and time constraints. We construct a novel household panel data set that combines purchase records for grocery goods with information on labor market status and other demographics. We use the data to document that, in line wi...

摘要：In credit markets, screening algorithms aim to discriminate between good-type and bad-type borrowers. However, when doing so, they can also discriminate between individuals sharing a protected attribute (e.g., gender, age, racial origin) and the rest of the population. This can be unintentional and originate from the training data set or from the model itself. We show how to formally test the algorithmic fairness of scoring models and how to identify the variables responsible for any lack of f...

摘要：This paper investigates the market consequences of sovereign accounting errors, opening a new area of research on sovereign accounting quality in the accounting literature. Eurostat, a division of the European Commission, provides semiannual assessments of financial reports produced by the member states of the European Union (EU) and issues reservations that detail financial reporting errors. Using a sample of Eurostat reservation issuances across 28 EU countries from 2004 to 2018, we find tha...

摘要：Decisions with risky consequences at multiple points in time are driven not only by risk attitudes and time preferences but also by attitudes toward intertemporal correlation (i.e., the correlation between outcomes at different points in time). This paper proposes a model-free method to measure degrees of intertemporal correlation aversion. We disentangle attitudes toward positive and negative intertemporal correlation, which can differ if expected intertemporal utility is violated. In an expe...

摘要：We find the Small Business Administration's disaster -relief home loan program denies significantly more loans in areas with larger shares of minorities, subprime borrowers, and higher income inequality. We find that risk -insensitive loan pricing, a feature present in many regulated and government -run lending programs, is an important driver of these disparities in access to credit. The differences in denial rates are disproportionately high compared with private -market lending and governme...

摘要：As digitization sweeps across industries and markets, analytics and data-driven decision making (DDD) are becoming increasingly important. The adoption of analytics and DDD has been slower in small-to-medium enterprises (SMEs) compared with large firms, and reliable causal estimates of the impacts of analytics tools for small businesses have been lacking. We derive experiment-based estimates of the impact of an analytics tool on SME outcomes, analyzing the randomized introduction of eBay's Sel...

摘要：Companies that are investing in blockchain technology to enhance supply chain transparency face challenges in fostering collaborations with others and deciding what information to share. Transparency over the actions of supply chain partners can improve operational decisions, but sharing own data on the blockchain can put firms at a competitive disadvantage. In this paper, we investigate the resulting questions of when blockchain should be adopted in a supply chain and how it should be designe...

摘要：We estimate an infinite-horizon dynamic oligopoly model of audit firm tenure and misstatements and evaluate a policy counterfactual involving mandatory audit firm rotation. Longer tenure lowers the cost of producing audits, increasing audit quality and reducing audit fees. Thus clients are less likely to misstate and more likely to keep the incumbent audit firm as tenure increases. By reducing the value of retaining audit firms, mandatory rotation leads to large increases in auditor switches, ...

摘要：A merchant dynamically sets prices in each time period when selling a product over a finite time horizon with a given initial inventory. The merchant utilizes new external information that is observed at the beginning of each time period, whereas the demand function-how the external information and the price jointly impact that single-period demand distribution-is unknown. The merchant's decision, setting price dynamically, serves dual roles to learn the unknown demand function and to balance ...

摘要：This paper shows how convex incentives in vertical contracts between manufacturers and retailers can induce sales behavior with costs to consumers. We examine this problem in the automotive sector, where manufacturers commonly motivate new vehicle sales through dealer incentive programs with large discrete bonuses determined by monthly sales targets. Using subprime car loans from over 3,500 dealerships, we document high default rates on new car loans originated at the end of the month-the peri...
