摘要 Abstract of the paper	We construct a trading framework involving vertically related markets to examine the optimal international licensing under endogenous tariff, in which a foreign vertically integrated firm has a cost-reducing technology of the downstream product competing against domestic upstream and downstream firms in domestic markets. We obtain the following results. First, the foreign licensor will choose royalty licensing with the royalty rate equaling two times of the innovation size if the innovation size is low, while choosing mixed licensing otherwise. Second, the fixed-fee licensing can never occur. Third, licensing will always lower the welfare of the domestic country. Fourth, the equilibrium tariff rate will be first increasing, then decreasing, and then increasing, when the innovation size becomes higher. Lastly, the optimal royalty rate will be increasing, then remain increasing but the optimal royalty rate drops to a lower level, and then decreasing in the innovation size.
