Rewarding Sequential Innovators: Prizes, Patents and Buyouts

  • Llobet, G.
  • Hopenhayn, H.
  • Mitchell, M.

This paper presents a model of cumulative innovation where firms are heterogeneous in their research ability. We study the optimal reward policy when the quality of the ideas and their subsequent development effort are private information. The optimal assignment of property rights must counterbalance the incentives of current and future innovators. The resulting mechanism resembles a menu of patents that have infinite duration and fixed scope, where the latter increases in the value of the idea.
