November 2015Taste for Competition and the Gender Gap Among Young Business Professionals
with Paola Sapienza, Luigi Zingales: w21695
Using an incentivized measure of test for competition, this paper investigates whether this taste explains subsequent gender differences in earnings and industry choice in a sample of high-ability MBA graduates. We find that “competitive” individuals earn 9% more than their less competitive counterparts do. Moreover, gender differences in taste for competition explain around 10% of the overall gender gap. We also find that competitive individuals are more likely to work in high-paying industries nine years later, which suggests that the relation between taste for competition and earnings persists in the long run. Lastly, we find that the effect of taste for competition emerges over time when MBAs and firms interact with each other.
December 2007Procrastination and Impatience
with Paola Sapienza, Luigi Zingales: w13713
There is a large body of literature documenting both a preference for immediacy and a tendency to procrastinate. O'Donoghue and Rabin (1999a,b, 2001) and Choi et al. (2005) model these behaviors as the two faces of the same phenomenon. In this paper, we use a combination of lab, field, and survey evidence to study whether these two types of behavior are indeed linked. To measure immediacy we had subjects choose between a series of smaller-sooner and larger-later rewards. Both rewards were paid with a check in order to control for transaction costs. To measure procrastination we use the subjects' actual behavior in cashing the check and completing tasks on time. Our results lend support to the hypothesis that subjects who have a preference for immediacy are indeed more likely to procrastina...
