DP10095 Staggered Contracts, Market Power, and Welfare

I show that exclusive, staggered supply contracts can decrease industry competition when there are economies of scale: buyers pay a higher price to the incumbent seller and the expected value received by an entrant seller is lower when contracts are staggered. Moreover, under staggered contracts there may exist equilibria where an inefficient firm forecloses a more efficient one. Given that contracts are staggered, contract length further increases market power; however, increasing contract length may also eliminate the inefficient foreclosure equilibrium. Finally, I show that, allowing firms to choose contract structure endogenously, the resulting equilibrium path features staggered contracts.
