An incentive model of partial information sharing in supply chain

Considering one manufacturer and two retailers in supply chain based on part of retailers to participate in information sharing, we use price discrimination strategy to design an incentive mechanism which motivates retailers to share uncertain demand information with manufacturer. The research results show that information sharing may be value-added to add their profits only in under certain conditions using price discrimination strategies. And then we put forward the strict constraints and improve the information sharing incentive model under demand uncertain environment. When the retailers´ external environment and their capacity are the same, i.e., they are perfect competition, the full information sharing is stable Pareto optimal equilibrium in the improved incentive model.
