Abstract: A newsvendor model and a decentralized supply chain model were considered based on strategic customer behaviors. Product availability and supply chain performance under wholesale price contract, quantity discounting contract and two-part tariff were discussed by analyzing rational expectations equilibrium between sellers and customers. Results showed that two-part tariff improved supply chain profits, while high profit was accompanied by high product availability. However, supply chain performance under wholesale price contract or quantity discounting contract couldnt achieve the profit level made by centralized supply chain. Due to the existence of strategic customer behaviors, manufacturers under two-part tariff should set the wholesale price below marginal production cost to increase product availability, so as to raise supply chain profit.

Key words: strategic customer behavior, supply chain contract, product availability, rational expectations equilibrium, newsvendor model, supply chains
