Using every major nationally-representative dataset on parental and non-parental care provided to children up to age 6, we quantify differences in American children's care experiences by socioeconomic status (SES), proxied primarily with maternal education. Increasingly, higher-SES children...

This study investigates the dynamics of between-group and within-group wage inequality in a model with heterogeneous learning abilities putting a key emphasis on the shape of the ability distribution. In our model, intergenerational human capital externalities incentivize individuals to invest...

To examine how human capital accumulation influences both economic growth and income inequality, we carefully endogenize the demand and supply of skills. We explicitly introduce the costs and externalities in education, and examine how both relate to learning-by-doing and R&D intensity. In...
