Dynamic Spatial Monopoly with Product Development

Author

Listed:
  • Luca Lambertini

Abstract

Abstract The optimal R&D investment in product innovation of a profit-seeking monopolist is characterized vs that of a social planner in a spatial market with transportation disutility, under full market coverage. It is shown that the planner's incentive to innovate is always weaker than the monopolist's, since the planner trades off the minimization of the social cost of transportation against the cost of R&D.
