Correlations between Brothers and Neighboring Boys in Their Adult Earnings: The Importance of Being Urban

A comparison of the correlations between brothers and neighboring boys in their adult earnings suggests that the earnings resemblance between brothers stems more from growing up in the same family than from growing up in the same neighborhood. Much of the neighbor correlation is explicable in terms of the large earnings differential between urban and nonurban areas combined with the strength with which urbanicity of childhood neighborhood predicts urbanicity of adult location. This pattern is subject to a variety of interpretations, but it is quite different from the usual view of neighborhood effects.
