【Abstract】 In a two-echelon supply chain of perishable goods consisted by a supplier and multi-retailers, the market price is exogenous, the retailers are symmetry and they sell the same perishable product, the market demand is stochastic. There (exist) inventory competition among them. When the supplier adopts buy back contract, the retail inventory game exists an (unique) pure-strategic Nash equilibrium. Buy back contract can coordinate the above supply chain and divide the whole (expected) profit between supplier and retailers arbitrarily. At last we discuss some reasons why Buy back contract is popular in practice.更多还原
