We study when preferences for competition are a positive economic trait among high earners and the extent to which this trait can explain the gender gap in income among a master's degree in business administration (MBAs). Consistent with the experimental evidence, preferences for competition are a positive economic trait only for individuals who are not overconfident. Preferences for competition correlate with income only at graduation when bonuses are guaranteed and not a function of performance. Overconfident competition‐loving MBAs observe lower compensation and income growth, and experience greater exit from high‐reward industries and more frequent job interruptions. Preferences for competition do not explain the gender pay gap among MBAs.

We study whether gender influences credit attribution for group work using observational data and two experiments. We use data from academic economists to test whether coauthorship matters differently for tenure for men and women. We find that, conditional on quality and other observables, men are tenured similarly regardless of whether they coauthor or solo author. Women, however, are less likely to receive tenure the more they coauthor. We then conduct two experiments that demonstrate that biases in credit attribution in settings without confounds exist. Taken together, our results are best explained by gender and stereotypes influencing credit attribution for group work.

This article investigates gender differences in the job search process in the field and lab. Our analysis is based on rich information on initial job offers and acceptances from undergraduates of Boston University’s Questrom School of Business. We find (i) a clear gender difference in the timing of job offer acceptance, with women accepting jobs substantially earlier than men, and (ii) a sizable gender earnings gap in accepted offers, which narrows in favor of women over the course of the job search period. To understand these patterns, we develop a job search model that incorporates gender differences in risk aversion and overoptimism about prospective offers. We validate the model’s assumptions and predictions using the survey data and present empirical evidence that the job search patterns in the field can be partly explained by the greater risk aversion displayed by women and the higher levels of overoptimism displayed by men. We replicate these findings in a laboratory experiment that features sequential job search and provide direct evidence on the purported mechanisms. Our findings highlight the importance of risk preferences and beliefs for gender differences in job-finding behavior and, consequently, early-career wage gaps among the highly educated.
