Gender differences in health and education are a concern for a number of developing countries. While standard theory predicts human capital should respond to market returns, social norms (e.g., disapproval of women working outside the home) may weaken or even sever this link for girls. Though many studies have examined the link between women's wages or labor force participation and investment in girls, two significant problems are the possibility of omitted variables bias and reverse causality, and difficulty in identifying which of several mechanisms (returns, bargaining power, income, etc.) link the two. To overcome these problems, we provided three years of recruiting services to help young women in randomly selected Indian villages get jobs in the business process outsourcing industry. Girls in treatment villages were more likely to be in school and had greater measured BMI. We argue that the design of the experiment (providing opportunities almost exclusively for young, unmarried women rather than current mothers) allows us to rule out that mechanisms other than increases in the returns explain our results.

Caloric intake and minimum calorie thresholds are widely used in developing countries to assess hunger and nutrition, and to construct poverty lines. However, it is generally recognized that the sufficiency of an individual's caloric intake cannot be determined, due to: a lack of consensus on the true thresholds; the fact that any such thresholds are individual-varying and unobservable; imperfect nutrient absorption; and the weak and non-monotonic empirical relationship between calories and wealth. We propose a revealed preference approach to measuring hunger and undernutrition that overcomes these challenges. Low caloric intake is associated with a large utility penalty (e.g., physical discomfort). The corresponding high marginal utility of calories causes a utility-maximizing consumer to primarily consume the cheapest available source of calories (a staple). Once they have surpassed subsistence, the marginal utility of calories declines significantly and they substitute towards foods with higher levels of non-nutritional attributes (e.g., taste). Thus, though any individual's requirements are unobserved, their choice to switch away from the staple reveals they are above that requirement. Accordingly, the percent of calories obtained from the staple can be used to indicate nutritional sufficiency. We also provide an application for China that shows the desirable empirical properties of this approach.
