This study attempts to estimate the value marginal product and the marginal internal rate of return for agricultural research in Finland. Based on production function analysis, different Cobb-Douglas and linear models are specified and estimated. A variable for the research input is measured through the flow of public expenditures for research and university-level education in 1950—1984. In addition, a stock of research capital consisting of funds accumulated since 1920 is constructed and included in the models. The estimates of elasticity with respect to public research are used to compute rates of return. State expenditures for extension agencies are also taken into account on the cost side. It is concluded that the stock of research capital estimates are more believable than the flow estimates, because of difficulties in identifying an appropriate lag. Based on the stock estimates, the value marginal product for public research during the period studied seems to have been 1.83—1.91. The conclusion implies that additional public investment in agricultural research would have annually returned by 183—191 % over the inflation rate. The marginal internal rate of return for public research is calculated to have been 20—62 % depending on the length of the lag (4—10 years).
