Abstract: The present paper studies and compares different vertical integration structures on consumers and total surplus with licensing by mean of a fixed fee in two successive homogeneous-good Cournot duopolies where one of the firms in each market has a different cost-reducing innovation. The key difference between the present model and models in the existing literature is that here we suppose the existence of two different patents in upstream and downstream markets. In each market we find two firms: the patent holding firm and a non innovative firm. In upstream market, the innovative firm owns an innovation allowing to reduce the input marginal production cost. In downstream market the innovative firm owns an innovation allowing to reduce marginal cost of transforming the input into output. We discuss different structures of vertical integration and we show that consumer surplus and total surplus are depending of cost-reducing innovation in upstream and downstream markets and the structure of vertical integration.
