Local Intergenerational Mobility

Using NLSY data we investigate whether the observed patterns of economic mobility (as measured by income and educational attainment) exhibit heterogeneity across socioeconomic groups and whether the nature of the heterogeneity can be explained by different levels of persistence in the intergenerational transmission of cognitive and non-cognitive abilities across these groups. In doing so we employ the varying coefficient model (VCM) to estimate nonparametric (local) measures of intergenerational mobility of those outcome variables. By local we mean that the persistence coefficients are modeled as smooth functions of log parental permanent income. Our findings show that intergenerational mobility exhibits nonlinear patterns. Individuals with different parental income are characterized by different degrees of intergenerational mobility. Moreover, we find evidence that suggests cognitive abilities play a role in explaining intergenerational mobility. These findings provide some support for a new class of family investment models that emphasize the role of such abilities in economic mobility. (C) 2020 Elsevier B.V. All rights reserved.
