Numerous national transfer programs around the world are designed with uniform benefit schedules imposed by central governments, but implemented by local governments. The Productive Safety Net Program (PSNP) in Ethiopia, the second largest safety net in Sub Saharan Africa, is one such program....

Faster agricultural development requires understanding whether the inverse land size-yield relationship exists or not. To verify the presence of this relationship, this study decomposes a yield index into separate components attributable to (1) efficiency, (2) soil quality, (3) land size, (4)...

This paper examines husband and wife perspectives on the division of authority over agriculture-related decision-making within households in Tanzania and Mali. We develop a theoretical model of intrahousehold “accord,” defined as the level of agreement between husbands and wives over who...

The relationship between income and nutrient intake is explored. Nonparametric, panel, and quantile regressions are used. Engle curves for calories, fat, and protein are approximately linear in logs with carbohydrate intakes exhibiting diminishing elasticities as incomes increase. Elasticities...

With the increasing frequency of extreme climatic events, the new challenge is to develop rice varieties that are tolerant of drought, water submergence, and salinity. There are now new high yielding GSR cultivars developed at the International Rice Research Institute (IRRI) with increased...

This paper discusses the application of the equilibrium displacement model (EDM) to estimate ex-ante the welfare effects of biological productivity growth for semi-subsistence crop and its impact on poverty reduction. The conventionally used EDM is compared with an alternative model (alternative...
