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. |
