Pricing,distribution and the supply of storage

The Belgian nitrogen fertilizer cartel announces each year a price schedule which is enforced during the coming twelve months. These prices are resale prices to final users and reflect changes in costs of storage. A game-theoretic model is set up to rationalize this behavior for the case of instantaneous final demands and a large number of distributors. Habit formation in final demand is then shown to lead to even more flexible prices, while transferability over time is seen to favor more rigid prices. It is finally suggested that vertical integration into a competitive distribution sector can be profitable because it restores the possibility of intertemporal price discrimination.
