Agricultural economics bulletin for Africa no.14

Abstract

This paper summarizes seven studies of research and extension investment, chiefly in the United States, and attempts to relate the to the policy decisions facing contemporary Africanization. An attempt is made to formalize an economic framework, which yields implications for research policy. Decisions with respect to the extent and form of investment in agricultural research and extension are likely to be of greater importance in the coming years or efficiency gains in food and fiber production. The process of real technology creation is only partially understood in all of its complex dimensions.
