Collateral requirements play an important role in credit markets. This paper shows that the endowment effect--the phenomenon where owing a good increases one's valuation of it--inhibits demand for loans which use a borrower's existing assets as collateral. Using a field experiment in Kenya, we...

Almost 50 million Americans are burdened by the need to repay almost $2 trillion in student loan debt, while at the same time having to save for retirement. This article analyzes the potential impact of the 2022 SECURE 2.0 Act reform which permits employers to match contributions for student...

Poor debt-management skills lower financial security and wealth accumulation. Because optimal solutions to credit repayment problems depend on neither risk preferences nor beliefs, loan repayment is a prime application for robo-advising. Vulnerable households, though, tend to distrust new...

Information provision, choice simplification, social messaging, active-choice frameworks, and automatic enrollment all increase retirement savings. However, gauging the relative efficacy of these approaches is challenging because the supporting evidence spans widely different institutional...

For many Americans the question of when to claim Social Security benefits is one of the most consequential financial decisions they will ever face. While acknowledging that individuals differ in terms of optimal timing for starting Social Security benefits, many economists argue that an average...

How do aspirations influence investment decisions for people living in poverty? Does this change as peoples economic conditions improve? To answer these questions, we design a workshop teaching techniques to raise aspirations and plan to achieve them. We cross-randomise this with large...

I review the academic literature on defined contribution retirement plan design and participant behavior. While adoption of automatic enrollment has significantly increased participation rates, recent studies find the long-run effects on savings are smaller than the short-run effects, with some...

We document a causal effect of social interactions on investor behavior using the number of local soccer games as a measure of social interaction intensity. Social transmission is identifiable in buy but not sell trades. The effect of Social Interaction Intensity (SII) on the sensitivity of...

'Epidemiological' models of belief formation put social interactions at their core; such models are widely used by scholars who are not economists to study the dynamics of beliefs in populations. We survey the literature in which economists attempting to model the consequences of beliefs about...

We use four incentivized representative surveys to study the endowment effect for lotteries in 4,000 U.S. adults. We replicate the standard finding of an endowment effect--the divergence between Willingness to Accept (WTA) and Willingness to Pay (WTP), but document three new findings. First, we...
