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...

Cowpea (Vigna unguiculata) is an important staple in Burkina Faso as well as many other countries in West Africa. Among the major cowpea pests affecting the crop are the legume pod borer (Maruca vitrata), flower thrips (Megalurothrips sjostedti), bruchids (Callosobruchus maculatus), and...

A non-neutral stochastic distance function model is used to examine whether output specialization has an impact on the economic performance of vegetable producers in Benin. Specialization is assumed to have an effect on the production frontier and on the distance to the production frontier...

We study the effects of informal labor sharing arrangements and other social interactions on farmers' productivity in a developing country context, testing whether these types of social and work interactions lead to productivity gains through learning, synergy, or both. Using a rich panel data...

An important hypothesized benefit of large-scale input subsidy programs in Africa is that by raising maize production, the subsidies should put downward pressure on retail maize prices to the benefit of urban consumers and the rural poor who tend to be net food buyers. To inform debates related...

Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. The innovations of the...
