Ex post impact assessment of agricultural research in subSaharan Africa: the IITA experience
This paper examines the adoption and impact of selective and whole package adoption of improved cowpea involving new variety, insect control, fertilizer, and best bet cropping pattern in northern Nigeria. A farm income model that explicitly accounts for endogenous technology adoption was used to ...

Gains from highyielding varieties with and without complementary technologies: the case of improved cowpea in northern Nigeria
This paper estimates a more efficient version of an endogenous switching regression model to examine the effects of farmer education—schooling and extension contact—on cowpea production under traditional and improved technology in northern Nigeria. The results revealed significant productivity-en...
