We semiparametrically estimate the impact of the Mexican conditional cash transfer program Oportunidades on the time mothers and older sisters spend taking care of children aged under 3, using the randomization of the program placement and the methodology in Lewbel (2000). Results support the...

How far has English already spread? How much further can we expect it to go? In response to the first question, this chapter tries to identify the areas of life where English already serves as a lingua franca in the world (more or less) and those where the language faces sharp competition and...

How has wellbeing evolved over time and across regions? How does the West compare to the Rest? What explains their differences? These questions are addressed using an historical index of human development. A sustained improvement in wellbeing has taken place since 1870. The absolute gap between...

Immigration is an important problem in many societies, and it has wide-ranging eects on the educational systems of host countries. There is a now a large empirical literature, but very little theoretical work on this topic. We introduce a model of family immigration in a framework where school...

We study a model where student eort and talent interact with parental and teachers' investments, as well as with school system resources. The model is rich, yet sufficiently stylized to provide novel implications. We can show, for example, that an improvement in parental outside options will...

We model a South African city during Apartheid (in which both schooling and mobility are restricted on the basis of race) and after Apartheid (in which no restrictions are imposed). We first show that the inequality between blacks and whites decreases when Apartheid laws are removed. Indeed,...

There is a well-established high quality literature on the role of networks, particularly ethnic networks, in international trade. Ethnic networks are a way of overcoming informal barriers (information costs, risk and uncertainty) to trade by building trust and substituting for the difficulty of...
