We combine a customized survey and randomized controlled trial (RCT) to study the effect of higher-order beliefs on U.S. retail investors' portfolio allocations. We find that investors' higher-order beliefs about stock market returns are correlated with but distinct from their first-order...

Women are less financially literate than men. It is unclear whether this gap reflects a lack of knowledge or, rather, a lack of confidence. Our survey experiment shows that women tend to disproportionately respond "do not know" to questions measuring financial knowledge, but when this response...

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...

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 strikingly...

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...

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...

This lecture considers the case for consumer financial regulation in an environment where many households lack the knowledge to manage their financial affairs effectively. The lecture argues that financial ignorance is pervasive and unsurprising given the complexity of modern financial products,...

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...
