Content Introduction:Strategic inventory refers to the inventory held by firms purely out of strategic considerations other than operational reasons (e.g., economies of scale). In this paper, we investigate the roles of strategic inventory in a system with two parallel supply chains under both full bargaining and partial bargaining, which differ in whether inventory is included in the bargaining terms. We find that under full bargaining, horizontal competition can induce an asymmetric equilibrium whereby only one of the chains carries strategic inventory and benefits from it when the holding cost is small. The whole system, however, is worse off. Under partial bargaining, regardless whether there is horizontal competition, the retailer in a supply chain always carries inventory when his bargaining power is small and the inventory holding cost is low.Furthermore, with horizontal competition, inventory hurts (improves) the system performance when the inventory holding cost is small (above a threshold and not too big). We also find that full bargaining can be inferior to partial bargaining when where is horizontal competition.
