Abstract

The impact of public and private research to agricultural productivity in the US between 1950 and 1982 were assessed using an econometric model. Analysis of US aggregate measures of multifactor agricultural productivity was undertaken using imputation-accounting, statistical meta-function and statistical productivity decomposition methods. The study indicated that public sector research should be focused on general and pretechnology sciences while private sector resources should be channeled to applied research and technology advancement.
