Causal inference lies at the heart of social science, and the 2019 Nobel Prize in Economics highlights the value of randomized variation for identifying causal effects and mechanisms. But causal inference cannot rely on randomized variation alone; it also requires good data. Yet the...

Debit cards are overtaking credit cards as the most prevalent form of electronic payment at the point of sale, yet the determinants of a ubiquitous consumer choice - debit or credit? - have received relatively little scrutiny. Several stylized facts suggest that debit-card use is driven by...

Consumer installment lenders prefer to market ldquo;low monthly paymentsrdquo; and shroud interest rates. Why not voluntarily disclose rates? We show that when an interest rate is not disclosed, most consumers substantially underestimate it using information on the monthly payment, loan...

The one-third rise in the teen smoking rate in the 1990s has led to considerable interest in understanding the determinants of the youth smoking decision. We explore four aspects of this decision. First, we consider the demographic correlates of smoking participation, and find that smoking...

Can a behavioral sufficient statistic empirically capture cross-consumer variation in behavioral tendencies and help identify whether behavioral biases, taken together, are linked to material consumer welfare losses? Our answer is yes. We construct simple consumer-level behavioral sufficient...

Many policymakers and some behavioral models hold that restricting access to expensive credit helps consumers by preventing overborrowing. I examine some short-run effects of restricting access, using household panel survey data on payday loan users collected around the imposition of binding...

Does borrowing at 400 percent APR do more harm than good? The Pentagon asserts that payday loans harm military readiness and successfully lobbied for a binding 36 percent APR cap on loans to military members and their families (effective October 1, 2007). But existing evidence on how access to...

Two for-profit Philippine social enterprises, aiming to demonstrate corporate social responsibility by increasing microlending to the poor, incorporated a widely-used poverty measurement tool into their loan applications and tested the tool using randomized training content. Treated loan...

Behavioral economics lacks empirical evidence on some foundational empirical questions. We adapt standard elicitation methods to measure multiple behavioral factors per person in a representative U.S. sample, along with financial condition, cognitive skills, financial literacy, classical...

Behavioral economics identifies myriad deviations from classical economic assumptions about consumer decision-making, but lacks evidence on how its diverse phenomena fit together and whether they are amenable to modeling as low-dimensional constructs. We pursue such parsimony on three fronts,...
