This paper studies how market competition influences the algorithmic design choices of firms in the context of targeting. Firms face the general trade-off between bias and variance when choosing the design of a supervised learning algorithm in terms of model complexity or the number of...

Regulation consists of rulemaking and enforcement. Economic theory offers two complementary rationales for regulating financial institutions. Altruistic public-benefits theories treat rules as governmental instruments for increas- ing fairness and efficiency across society as a whole....

Explanations of unethical behavior often neglect the role of competition, as opposed to greed, in assuring its spread. Using the examples of child labor, corruption, excessive' executive pay, corporate earnings manipulation, and commercial activities by universities, this paper clarifies the...

This paper investigates whether judge political affiliation contributes to racial and gender disparities in sentencing using data on over 500,000 federal defendants linked to sentencing judge. Exploiting random case assignment, we find that Republican-appointed judges sentence black defendants...

We conduct a field experiment in partnership with the largest job platform in Brazil to study how environmental, social, and governance (ESG) practices of firms affect talent allocation. We find both an average job-seeker's preference for ESG and a large degree of heterogeneity across...

Digital platforms are not only match-making intermediaries but also establish internal rules that govern all users in their ecosystems. To better understand the governing role of platforms, we study two Airbnb pro-guest rules that pertain to guest and host cancellations, using data on Airbnb and...

We use minute-by-minute depositor withdrawal data to understand the effectiveness of deposit insurance, the role of social networks, and the importance of bank-depositor relationships in influencing...

We test whether firms use incompatibility strategically, using data from ATM markets. High ATM fees degrade the value of competitors' deposit accounts, and can in principle serve as a mechanism for siphoning depositors away from competitors or for creating deposit account differentiation. Our...
