Information Sharing in a Supply Chain with Learning Effect
摘要
Abstract
There exist both vertical and horizontal information sharing in supply chains.Based on a supply chain with learning effect, to study the impact of information sharing across decentralized retailers in a supply chain, a supply chain model with horizontal information is proposed.By constructing a Cournot competition model, we solve equilibrium order quantity and information sharing strategy for retailers.In this model, the manufacturer supplies similar products to multiple retailers and each retailer serves its independent end market.Retailers face one period of demand and can satisfy the demand by ordering in the first period or back-ordering some of the demand and satisfying it in the second period.Because of the learning effect in the manufacturer side, the wholesale price in the second period decreases in the total order size, across the retailers, in the first period.Retailers should agree on information sharing before they observe demand.We show that retailers have no incentives to share information about their private values when equilibrium order quantities are interior, i.e., the order size is between zero and the demand.This result is contrary to the result in oligopoly models on information sharing.In addition, we show that the impact of information sharing decreases when there are more retailers.This result is valuable for companies to choose strategy of information sharing.关键词
