The present study aims at assessing the impact of the public agricultural research and development (R&D) on the total factor productivity in Catalonia. To do so, we use a complementary approach based on econometric and accounting techniques to examine the relationship between public investments in agricultural R&D and the productivity growth over the period 1985–2015. Results show that the productivity grew on average at an annual rate less than one percent. However, the growth was much faster during the tow first decades of the analysis. In addition, our empirical findings indicate that the public agricultural R&D has a significant and positive impact on the Catalan agricultural productivity. From a cost–benefit perspective, the estimates reveal a high return (15-28%) to R&D investments which has contributed to improve the productivity performance of the agricultural sector in Catalonia.
