In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of...

Replaced with revised version of paper 07/22/11. Former Title: Revisiting the Returns to U.S. Public Agricultural Research: New Measures, Models, Results, and Interpretation

Estimated rates of return to research are distorted by problems of attributing the credit for particular research results, or for particular research-induced productivity increases, among research expenditures undertaken at different times, in different places, and by different agencies. A...

The effects of functional forms for supply and demand on the size and distribution of the returns to research are examined under a range of forms of competition. Under perfect competition, the choice of functional form is relatively unimportant for the estimation of research benefits. Under...

Selected Paper presented at the 57th annual conference of the Australian Agricultural and Resource Economics Society, Sydney, February 5-8, 2013.

We use newly constructed data to model and measure agricultural productivity growth and the returns to public agricultural research conducted in Uruguay over the period 1961–2010. We pay attention specifically to the role of levy-based funding under INIA, which was established in 1990. Our...
