An Economic Evaluation of Public Wheat Research and Extension Expenditures in Canada*

The widespread commitment of public funds to agricultural research is being questioned by administrators in governments and by the Canadian public. Questions relating to the level of public expenditure on agricultural research, the efficiency with which the resources are being allocated, and the manner in which the benefits are distributed among members of society art being asked. This study addresses these and related questions as they pertain to publicly funded wheat research activities conducted over the period 1946 to 1979- Two research scenarios were examined - one dealing with the development of new varieties of wheat and the other dealing with all research applicable to the production of wheat. The results revealed that society has indeed benefitted substantially from public investment in wheat research. The level of social benefits averaged $49 and $143 million (measured in 1971 dollars) annually for the wheat breeding and all-wheat research scenarios, respectively. The average annual internal rates of return earned from these public investments ranged between 30 and 39 percent. Furthermore, some evidence was presented that suggests society may, in fact, be underin-vesting in agricultural research in the aggregate. Finally, analyses of the distribution of the benefits showed that both producers and consumers are major beneficiaries.
