摘要

Abstract of the paper

 We construct a model of vertically related markets to examine the optimal international licensing with differential tariffs where a foreign vertically integrated firm owns a cost-reducing technology of the downstream product competing against one domestic downstream firm and one domestic upstream firm in domestic markets. We show that, first, when the downstream tariff is relatively low, medium, and high, the optimal licensing is royalty licensing with the royalty rate equaling two times of the innovation size, mixed, and fixed-fee licensing, respectively. Second, given exogenous tariffs, the welfare post licensing can be lower than under no licensing. Third, the optimal downstream tariff is higher than the upstream tariff under both the absence and presence of licensing. Fourth, a fixed-fee licensing can never occur, when tariffs are endogenously determined. Lastly, we depict the areas of combinations of upstream and downstream marginal costs corresponding to the optimal licensing contracts under endogenous tariffs.
