Abstract

The benefits of agricultural research and extension are examined in an ex ante consumer-producer surplus framework for five commodities in Peru. The effects of demand shifts over time and government pricing policies on research and extension benefits are considered. Data for the analysis include the results of research and extension questionnaires administered at seven sites in Peru. The projected rates of return to research and extension indicate substantial returns to public investments.
