This paper explores the cross-fertilization potential that exists between the economic theory of agricultural cooperatives and that of nonprofit organizations. A number of central ideas in the agricultural cooperative theory are shown to generate two novel insights pertaining to the nonprofit economics literature. First, as with agricultural cooperatives, nonprofit organizations can be conceptualized not only as firms but also as service agencies and stakeholder coalitions. Second, the demand-side economic justification of nonprofit organizations, like that of agricultural cooperatives, likely includes reasons other than market failure. The paper concludes by calling for research on how nonprofit economics can inform the theory of agricultural cooperatives.
