We examine the welfare implication of technology licensing and input price discrimination in the vertically related market wherein two downstream firms purchase a cost-saving technology from an outside innovator and input factors from a monopolistic supplier to produce final goods. We show that input price discrimination affects the input prices and the mode of the license contract. The innovator strategically offers a royalty contract under discriminatory pricing but a fixed-fee contract under uniform pricing. Banning price discrimination improves social welfare and compensation to the innovator. Moreover, banning price discrimination may paradoxically accrue more profits to the monopolistic supplier.
