چکیده انگلیسی
A better understanding of the relationship between public investments in agricultural R&D and the productivity enhancing benefits they produce is critical to informing the public funding of agricultural R&D and insuring future increases in agricultural productivity. This paper describes a method of estimating the relationship between research investments, productivity growth, and the resulting economic benefits generated. The data requirements include indexes of multi-factor productivity, investments in R&D, and the value of agricultural output. The real rate of return to public investments in agricultural R&D in the United States is estimated to be 10.5% per annum; however, a reduction in the growth of spending on public agricultural R&D in recent decades raises concerns about productivity growth in coming decades, which is required to insure an adequate supply of food to meet increasing demand.
