The Monopolist's Optimal R&D Portfolio

Author

  • L. Lambertini

Abstract

The monopolist s incentives towards product and process innovations are evaluated against the social optimum. The main findings are that (i) the incentive to invest in cost-reducing R&D is inversely related to the number of varieties being supplied at equilibrium, under both regimes; (ii) distortions obtain under monopoly, w.r.t. both the number of varieties and the technology. With substitutes (respectively, complements), the monopolist s product range is smaller (respectively, larger) than under social planning. For any given number of goods, the monopolist operates at a higher marginal cost than the planner does.
