People use information about their ability to choose tasks. If more challenging tasks provide more accurate information about ability, people who care about and who are risk averse over their perception of their own ability will choose tasks that are not sufficiently challenging. Overestimation...

This paper develops a model of social interactions with endogenous association. People are assumed to invest in relationships to maximize their utility. Even in a linear-in-means model, when associations are endogenous, the effect of macro-group composition on behavior is non-linear and varies...

Using a new identification strategy and unique, rich data on Nobel laureates, we show that being in new or multiple locations, as measures of exposure to novel combinations of ideas, and the number of other local important innovators, all increase the probability that eventual Nobel laureates...

Characterizing the work that people do on their jobs is a longstanding and core issue in labor economics. Traditionally, classification has been done manually. If it were possible to combine new computational tools and administrative wage records to generate an automated crosswalk between job...

Vintage human capital models imply that young workers will be the primary adopters and beneficiaries of new technologies. Because technological progress in general, and computers in particular, may be skill-biased and because human capital increases over the lifecycle, technological change may...

We investigate the effects of maternity leave coverage on women?s post-birth wages, job tenure, and labor market attachment. We pay particular attention to unobservable characteristics that are correlated with maternity leave coverage and that affect labor market outcomes. We use a control...

Despite indications that interpersonal interactions are important for understanding individual labor-market outcomes and have become more important over the last decades, there is little analysis by economists. This paper shows that interpersonal interactions are important determinants of...
