|May 2020||Necessary Evidence For A Risk Factor’s Relevance|
with Alexander M. Chinco, Samuel M. Hartzmark: w27227
Textbook finance theory assumes that investors strategically try to insure themselves against bad future states of the world when forming portfolios. This is a testable assumption, surveys are ideally suited to test it, and we develop a framework for doing so. Our framework combines survey experiments with field data to test this assumption as it pertains to any candidate risk factor. We study consumption growth to demonstrate the approach. While participants strategically respond to changes in the mean and volatility of stock returns when forming their portfolios, there is no evidence that investors view this canonical risk factor as relevant.
|July 2019||Does Knowing Your FICO Score Change Financial Behavior? Evidence from a Field Experiment with Student Loan Borrowers|
with Tatiana Homonoff, Rourke O'Brien: w26048
One in five consumer credit accounts incur late fees each quarter. Evidence on the efficacy of regulations to improve behavior through enhanced disclosure of financial product attributes is mixed. We test a novel form of disclosure that provides borrowers with a personalized measure of their creditworthiness. In a field experiment with over 400,000 student loan borrowers, treatment group members received communications about the availability of their FICO Score. The intervention significantly reduced late payments and increased borrowers’ FICO Scores. Survey data show treatment group members were less likely to overestimate their FICO Scores, suggesting the intervention may correct for overoptimism.
