The interplay between social arrangements, norms of behavior and economic variables has long been studied within economics. Observed differences in wealth and welfare between countries, neighborhoods or ethnic groups are often explained as multiple equilibria resulting from such differences in the underlying norms of behavior. In this paper we examine how the underlying matching arrangements within a social group interact with decisions the agents make regarding investments in human capital, where these decisions affect both the agent's prospects of future and the pool of future mates. We characterize stable arrangements where matching is assortative versus mixed. Next, we allow for mobility between social groups and identify an asymmetric equilibrium where the two groups are governed by different social arrangements, investment levels, and as a result different income distributions.
