A procedure is developed to examine the ex-post impacts of improved maize varieties on poverty in rural Ethiopia. Yield and cost effects of adoption are estimated econometrically under assumptions of both homogeneous and heterogeneous treatment effects. A backward derivation procedure is...

The triple challenge of rapid population growth, declining agricultural productivity, and natural resource degradation are not isolated from one another; they are intimately related. However, strategic planning and development programming tend to focus on individual sectors such as the...

We assess the relative impacts of receiving cash versus food transfers using a randomized design. Drawing on data collected in eastern Niger, we find that households randomized to receive a food basket experienced larger, positive impact on measures of food consumption and diet quality than...
