This paper examines productivity of a sample of grain marketing and farm supply cooperatives from 1990 to 1998. The cooperative industry's productivity or growth was mainly due to improvement in technology rather than improvement in pure efficiency or scale. The cooperative industry's productivity was primarily associated with the grain, fertilizer, and agrochemical product lines. Policies that raise fertilizer prices would encourage a cooperative to be technically more productive. In general, policies that raise prices of grain, fertilizer, and agrochemicals would encourage a cooperative to be more productive overall.
