Abstract

The main purpose of this article is to assess the impact of public agricultural research effort on agricultural total factor productivity in Catalonia. A complementary approach based on accounting and econometric techniques is applied to annual data over the period 1985–2015 to fit the relationship between agricultural total factor productivity (TFP) and agriculture research spending. The results show that TFP grows on average at an annual rate less than one percent. TFP growth was much faster during the tow first decades of the analysis, with a considerable slowdown in the last decade. Our empirical findings indicate that public agricultural research has statistically significant positive impact on Catalan agricultural productivity. Furthermore, from a cost–benefit perspective, our study reveals that the social marginal annualized real rate of return to public resources invested in agricultural research is about 15–28%.
