Two competing explanations for why consumers have trouble with financial decisions are gaining momentum. One is that people are financially illiterate since they lack understanding of simple economic concepts and cannot carry out computations such as computing compound interest, which could...

As the world becomes more financially integrated and complex, average individuals and their families are increasingly faced with making highly sophisticated and all-too-often irreversible financial decisions. Nowhere is this more evident than with regard to retirement decision-making. Indeed,...

Previous research shows that many people seek financial advice from non-experts, and that peer interactions influence financial decisions. We investigate whether such influences are beneficial, harmful, or simply haphazard. In our laboratory experiment, face-to-face communication with a randomly...

What contributes to the growing income inequality across U.S. households? We develop an information- based general equilibrium model that links capital income derived from financial assets to a level of investor sophistication. Our model implies income inequality between sophisticated and...

Using a unique new dataset linking administrative data on investment performance and financial knowledge, we examine whether investors who are more financially knowledgeable earn more on their retirement plan investments, compared to their less sophisticated counterparts. We find that...

Deciding how much to save for retirement can be complicated. Drawing on a field experiment conducted with the Department of Defense, we study whether such complexity depresses participation in an employer-sponsored retirement saving plan. We find that simplifying one dimension of the enrollment...

We study the rapidly growing literature on the causal effects of financial education programs in a meta-analysis of 76 randomized experiments with a total sample size of over 160,000 individuals. The evidence shows that financial education programs have, on average, positive causal treatment...

This lecture considers the case for consumer financial regulation in an environment where many households lack the knowledge to manage their financial affairs effectively.

We show that molecular variation in DNA related to cognition, personality, health, and body shape, predicts an individual’s equity market participation and risk aversion. Moreover, the molecular genetic endowments predict individuals’ return perceptions, most of which we find to be...

A four-factor model with two "mispricing" factors, in addition to market and size factors, accommodates a large set of anomalies better than notable four- and five-factor alternative models. Moreover, our size factor reveals a small-firm premium nearly twice usual estimates. The mispricing...
