英文文献摘要：
This paper explores conditions under which inequality across social groups can emerge from initially group-egalitarian distributions and persist across generations despite equality of eco- nomic opportunity. These conditions arise from interactions among three factors: the extent of segregation in social networks, the strength of interpersonal spillovers in human capital accumu- lation, and the responsiveness of relative wages to the skill composition in production. Social segregation is critical in generating these results: group inequality cannot emerge or persist un- der conditions of equal opportunity unless segregation su? ciently great. We also show that if an initially disadvantaged group is su? ciently small, integration above a threshold level can induce both groups to invest more in human capital, while the opposite holds if the disadvantaged group is large.
