The economic surplus approach is used to estimate the returns to federal investments in dairy cattle research in Canada. A national supply function is estimated using time series data. Lagged research expenditures are included as explanatory variables in the model, facilitating the calculation of marginal as well as average benefits from research. Simulation analysis is used to study the effects of product market distortions associated with Canadian dairy policy as well as of the marginal excess burden on the rates of return to research and on the distribution of research benefits. Returns were found to be high at the margin. Distortions in the product market had a small effect on the overall returns to dairy cattle research but had a large impact on the distribution of research benefits. Rate of return estimates were found to be indicative of underinvestment even when the marginal excess burden was taken into account.

This paper describes the Positive Mathematical Programming (PMP), amethod for calibrating models of agricultural livestock production and resource use using a nonlinear marginal cost function and illustrates the application of this method in agricultural sectoral models used to study changes in policy and market signals. The Canadian Regional Agricultural Model (CRAM) is a regional, multi-sectoral, comparative static, partial equilibrium, mathematical programming model developed and maintained by Agriculture and Agri-Food Canada. The hog sector is one of the components of the CRAM. In this application, the introduction of nonlinear relationships to improve the performance of sectoral models is emphasized for the hog sector. A cubic total cost function was chosen, based on the empirical research for the hog sector in Canada. Empirical research shows that the marginal cost function is convex for the hog sectorin Canada. The calibration constraints are removed and the model automatically calibrates at the base year production levels. The results indicate that the model is able to predict the impacts of changes in feed prices on the breeding herd size. Similarly, the model can predict changesin the herd size with respect to changes in pork prices.
