Plans conjoints et gestion de l'offre, un essai d'évaluation de leurs impacts

This article presents the main results of an analysis conducted to evaluate the impacts of Canadian agricultural marketing boards. Two types of marketing boards are considered. Those boards who do not control production seem to have an impact on prices at the farm level but not at the consumer level. The greater bargaining power given to producers is enabling them to capture a larger share of consumer food expenditures. Marketing boards who perform supply management functions exert more important upward pressures on prices at both levels. They also stabilize these prices. The problem of the monetary value taken by the production or marketing quotas under supply management is discussed and judged somewhat less important than other people have thought that they were so far.
