In this paper we show that the study of the farm size-productivity relationship hinges on the choice of productivity measure. Our main insight is that using yields, a partial measure of productivity, may not be informative for the size-productivity relationship because, in addition to total...

Crop biodiversity has the potential to enhance resistance to strains due to biotic and abiotic factors and to improve crop production and farm revenues. To investigate the effect of crop biodiversity on crop productivity, we build a probabilistic model based on ecological mechanisms to describe...

We examine whether returns to capital are higher for farmers who borrow than for those who do not, a direct implication of many credit market models. We measure the difference in returns through a two-stage loan and grant experiment. We find large positive investment responses and returns to...

The channels by which better health leads to higher income, and those by which higher income protects health status …, are of interest to both researchers and policy makers. In general, quantifying the impact of income on health is difficult …, given the simultaneous determination of health and income. In this paper, we quantify the impact on health status of a large …
