We design, pilot, and field a new survey of occupational skills in Peru, to investigate human capital differences between poor and rich countries. Though the average skill level is comparable, Peruvian jobs have markedly more uniform skill profiles than jobs in the US. However, matching...

In this study we argue that wage inequality and occupational mobility are intimately related. We are motivated by our empirical findings that human capital is occupation-specific and that the fraction of workers switching occupations in the United States was as high as 16% a year in the early...

We characterize optimal redistribution in a dynastic family model with human capital. We show how a government can improve the trade-off between equality and incentives by changing the amount of observable human capital. We provide an intuitive decomposition for the wedge between human-capital...

We develop and parameterize a two-sector, two-class, world economy model that endogenizes education and mobility decisions, population growth, and income...

We find a strong positive sibling spillover effect in two-children households in rural China, as measured by an increase in the Chinese and Math test scores of elder siblings when their younger sibling starts school. We use the Chinese Law of Compulsory Education as an exogenous variation in the...
