We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

The demographic history of the Jews in the Middle Ages may be characterized by two main phenomena: i) a sharp drop in the number of Jews until the beginning of the modern period, due mainly to conversions; and, ii) early urbanization. Until now, these features have been analyzed as primarily...

In this paper, location choices are driven by households (both blacks and whites) consciously choosing to trade off proximity to neighbors of similar racial backgrounds for proximity to jobs. Because of coordination failures in the location choices, multiple urban equilibria emerge. There is a...

If people come to live in a country different from their nation state, due to border shifts, expulsion, or migration, they adopt some of the new country?s habits after some time. This paper investigates their (return) migration decision when they have been restricted to live in the foreign...

In this paper we examine possible network formations among immigrants and natives with endogenous investment. We consider a model of a network formation where the initiator of the link bears its cost while both agents benefit from it. We present the model by considering possible interactions...

The speed at which immigrants assimilate is the subject of debate. Human capital formation plays a major role in this discussion. This paper compares the educational attainment of second generation immigrants to those of natives in the same age cohort. Evidence using a large German data set...

Are ethnic specialization and thus a downward sloping labor demand curve fundamental features of labor market competition between ethnic groups? In a general equilibrium model, this paper argues that spillover effects in skill acquisition and social distances between ethnic groups engender...

This paper models the tradeoffs between education in secular subjects, formal and informal, and the formation of religion-specific human capital. It explores some implications of negative externalities between religious and secular education. Applications include the tension between science and...

Expanding on the concept of ethnic human capital, the paper distinguishes between cultural assimilation compatible with persistent ethnic groups and assimilation through intermarriage and other mechanisms that blur distinctions and lead to the disappearance of ethnic identities. Economic...
