摘要 Abstract of the paper	Assume there is an outside innovator who owns a cost-reducing technology, which can be applied to one of the production stages of the product in question. The market structure of the industry is that of an n+1-stage successive monopoly. We shall examine the optimal licensing contract and the production stage the licensing to occur. It is found that the optimal licensing policy is that of a two-part tariff when the licensing occurs at a middle production stage. A pure fixed-fee is called for if the licensing occurs at the upmost production stage. Moreover, if the production technology exhibits a unitary input coefficient (i.e., one input to produce one unit of the output), the licensor’s profit and social welfare are both maximized when the licensing occurs at the upmost production stage. However, this result may be overturned if the input coefficient of the production technology is non-unitary. Furthermore, if the technology can be applied to all the production stages, the licensor’s optimal licensing contract is to charge a negative sum of royalty rates together with positive fixed-fees.
