his paper investigates the collective choice of production standards by farmer and pro- cessor groups within a vertical food supply chain, taking into account their competition behaviors. In a context in which raising standards cannot translate into a direct price premium to consumers, we develop a general model to analyze the strategic motive of us- ing standards to limit supply and shift rents among farmers and processors in the vertical chain. We find that such a motive depends on farmers’ cost structure, final demand char- acteristics, and processors’ competition patterns. In particular, farmers prefer a stringent standard when the standard involves creating greater diseconomies of scale in production and when the demand for the final product is inelastic. However, processors only prefer a stringent standard in the presence of oligopsony competition.
