La tarification dans les ensembles coopératifs

Pricing in Cooperatives - The recent crises that shook up the agricultural coops, namely in western France, have brought to light the importance of pricing in cooperatives. The following text will try to elucidate with the help of the marginalist theory -- but also referring to certain elements born of the modern financial theory -- how the various prices could be established in a coop. There lies an important distinction concerning cooperatives that do, or do not, apply the rule of exclusiviness : the first might follow the market, the latter might short-circuit some markets and work according to their own tarif-rate. To finish with, this article emphasizes the theoretical links existing between all the prices within the integrated societies : re-sale price practised by the coop, purchase price given to the cooperator and the sale price of supplies to the cooperator. The article ends on a note on incertainity that shows that the building up of a multivalent coop can still be interesting even if its purchase prices to the cooperator are below market level providing that the coop applies a tarif rate corresponding to the above mentioned model.
