The family investment hypothesis predicts that credit-constrained immigrant families adopt a household strategy for financing post-migration human capital investment in which the partner with labor market comparative advantage engages in investment activities and the other partner undertakes...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...

Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...

We examine the direct impact of idiosyncratic match quality on entry wages and job mobility using unique data on worker talents matched to job-indicators and individual wages. Tenured workers are clustered in jobs with high job-specific returns to their types of talents. We therefore measure...

Gender differences in math performance are now small in developed countries and they cannot explain on their own the strong under-representation of women in math-related fields. This latter result is however no longer true once gender differences in reading performance are also taken into...

Much research shows that students take account of their perceived comparative advantage in mathematics relative to verbal skills when choosing college majors and career tracks. There is also evidence for an important role for comparative advantage in explaining the gender gap in college STEM...

We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength...

Using a very large sample of matched author-referee pairs, we examine how the gender of referees and authors affects the former's recommendations. Relying on changing matches of authors and referees, we find no evidence of gender differences among referees in charitableness toward authors; nor...

Politicians can use the public sector to give jobs to cronies, at the expense of the efficiency of those organisations and general welfare. Motivated by a simple model of cronyism that predicts spikes in appointments to state-owned firms near elections, we regress 1980-2008 monthly hirings...

Despite being a fixture of everyday life in the Arab world, wasta, which may be thought of as special influence by members of the same group or tribe, has received little attention from social scientists. Our casual empiricism suggests that wasta is an important determinant of how economic...
