This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction.

We show that immigrant managers are substantially more likely to hire immigrants than are native managers. The finding holds when comparing establishments in the same 5-digit industry and location, when comparing different establishments within the same firm, when analyzing establishments that...

The literature has noted that native views about legal as opposed to undocumented immigration in the U.S. differ. Furthermore, native views about immigration are known to vary by gender. Yet, most surveys do not inquire native men and women about their views with regards to the two distinct...

This paper re-examines the role of labor-market competition as a determinant of attitudes toward immigration. We claim two main contributions. First, we use more sophisticated measures of the degree of exposure to competition from immigrants than previously done. Specifically, we focus on the...

The precondition for labour-market competition between immigrants and natives is that both are willing to accept jobs that do not differ in quality. To test this hypothesis, in this paper we compare the working conditions between immigrants and natives in Catalonia. Comparing immigrants' working...

Earlier studies on entrepreneurship and self-employment among immigrants call attention to the fact that also the market for self-employment or entrepreneurs consists of a supply and demand side as well as the interaction between these two. More recent research suggests that a mix of personal...

This chapter investigates the integration processes of immigrants in Germany by comparing certain immigrant groups to natives differentiating by gender and immigrant generation. Indicators which are supposed to capture cultural integration of immigrants are differences in marital behavior as...

Recent studies point to a positive correlation between ethnic heterogeneity due to immigration and the propensity of opting out from public schools for private alternatives. However, immigration across regions is hardly exogenous, which obstructs attempts to reveal causal mechanisms. This paper...

This paper investigates the transferability of human capital across countries and the contribution of imperfect human capital portability to the explanation of the immigrant-native wage gap. Using data for West Germany, our results reveal that, overall, education and labor market experience...

Trust is a crucial component of social capital. We use an experimental moonlighting game with a representative sample of the U.S. population, oversampling immigrants, to study trust, positive, and negative reciprocity between first-generation immigrants and native-born Americans as a measure of...
