If hours can be freely varied within jobs, the effect on hours of changes in preferences for those who do change jobs should be similar to the effect on hours for those who do not change jobs. Conversely, if employers restrict hours choices, then changes in preferences should affect hours more...

This paper concerns pitfalls associated with the use of approximations to dynamic Euler equations. Two applications of the approximations are notable. First, tests for precautionary saving motives typically involve regressing consumption growth on uncertainty in expected consumption growth. The...

A wide range of empirical applications rely on linear approximations to dynamic Euler equations. Among the most notable of these is the large and growing literature on precautionary saving that examines how consumption growth and saving behavior are affected by uncertainty and prudence. Linear...

We analyze longitudinal data from a demographic surveillance area (DSA) in KwaZulu-Natal, to examine the impact of parental death on children’s outcomes. We find significant differences in the impact of mothers’ and fathers’ deaths. The loss of a child’s mother is a strong predictor of...

This paper develops new methods for studying the adoption of technologies that, at the time of their introduction, are of uncertain profitability. We focus on the rols played by learning in the evolution of a diffusion path and present a model that allows learning from the behavior of others as...

Research across a number of disciplines has highlighted the role of early life health and circumstance in determining health and economic outcomes at older ages. Nutrition in utero and in infancy may set the stage for the chronic disease burden that an individual will face in middle age (David...

In many parts of the developing world, rural areas exhibit high rates of unemployment and underemployment. Understanding what prevents people from migrating to find better jobs is central to the development process. In this paper, we examine whether binding credit constraints and childcare...

We document the impact of the AIDS crisis on non-AIDS related health services in fourteen sub-Saharan African countries. Using multiple waves of Demographic and Health Surveys (DHS) for each country, we examine antenatal care, birth deliveries, and rates of immunization for children born between...
