A model is formulated incorporating linkages among nutrition, labor-market productivity, health heterogeneity, and the intrahousehold distribution of food and work activities in a subsistence economy. Empirical results, based on a sample of households from Bangladesh, indicate that, despite considerable intrahousehold disparities in calorie consumption, households are averse to inequality. Furthermore, consistent with the model, the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status.

We use a model of human capital investment and activity choice to explain facts describing gender differentials in the levels and returns to human capital investments. These include the higher return to and level of schooling, the small effect of healthiness on wages, and the large effect of healthiness on schooling for females relative to males. The model incorporates gender differences in the level and responsiveness of brawn to nutrition in a Roy-economy setting in which activities reward skill and brawn differentially. Empirical evidence from rural Bangladesh provides support for the model and the importance of the distribution of brawn.
