We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools. We argue that classes within primary schools are formed roughly randomly with respect to family background. Similar to previous studies, we find sizeable...

In May 1991, 15,000 Ethiopian Jews were brought to Israel in an overnight airlift and sorted in a haphazard and essentially random fashion to absorption centres across the country. This quasi-random assignment produced a natural experiment whereby the initial schooling environment of Ethiopian...

We develop a model that gives some microfoundation to the impact of residential neighborhood on children’s educational attainment and then test it using the UK National Child Development Study. We find that, for high-educated parents, the better the quality of the neighborhood in terms of...

Lucas' 1988 model of the external effects of human capital formation is used as a starting point for an analysis of the impact of human capital on wages. Most empirical tests of new growth theory are based on time-series and cross-section data. This paper suggests a microeconometric approach to...

This paper examines the issue of whether workers learn productive skills from their co-workers, even if those skills are unethical. Specifically, we estimate whether Jose Canseco, one of the best baseball players in last few decades, affected the performance of his teammates. In his...

How many "American jobs" have U.S.-born workers lost due to immigration and offshoring? Or, alternatively, is it possible that immigration and offshoring, by promoting cost-savings and enhanced efficiency in firms, have spurred the creation of jobs for U.S. natives? We consider a multi-sector...

We study a model that integrates productive and socialization efforts with network choice and parental investments. We characterize the unique symmetric equilibrium of this game. We first show that individuals underinvest in productive and social effort, but that solving only the investment...
