Risk aversion is typically inferred from real or hypothetical choices over risky lotteries, but such "untutored" choices may reflect mistakes rather than preferences. We develop a procedure to disentangle preferences from mistakes: after eliciting untutored choices, we confront participants with...

Job creation is one of the most important aspects of entrepreneurship, but we know relatively little about the hiring patterns and decisions of startups. Longitudinal data from the Integrated Longitudinal Business Database (iLBD), Kauffman Firm Survey (KFS), and the Growing America through...

A large share of the poor in developing countries run small enterprises, often earning low incomes. This paper explores whether the poor performance of businesses can be explained by a lack of basic business skills. We randomized the offer of a free, 48-hour business skills course to female...

Elite economics PhD programs aim to train graduate students for a lifetime of academic research. This paper asks how advising affects graduate students' post-PhD research productivity. Advising is highly concentrated: at the eight highly-selective schools in our study, a minority of advisors do...

Each year, thousands of students graduate high school academically unprepared for college. As a result, approximately one-third of entering postsecondary students require remedial or developmental work before entering college-level courses. However, little is known about the causal impact of...

How do college students and postsecondary institutions react to changes in skill demand in the U.S. labor market? We quantify the magnitude and nature of response in the 4-year sector using a new measure of labor demand at the institution-major level that combines online job ads with geographic...

Labor force participation rates of college-educated women ages 60 to 64 increased by 20 percent (10 percentage points) between 2000 and 2010. One potential explanation for this change stems from the fact that fewer college-educated women in the more recent cohorts were ever teachers. This...
