Patent Protection and R&D Incentives Under Incomplete Information

When tournament effect is negative, under complete information, whether patent protection increases the incentive for R&D is ambiguous. It depends on the extent of spillover of the new technology. In particular if that amount is less than a threshold value then patent protection increases the incentive for R&D, otherwise it does not. This note considers incomplete information framework where the spillover parameter is private information. In this framework it is shown that there are situations where patent protection unambiguously increases incentive for R&D. This happens if the distribution function of the spillover parameter is sufficiently skewed and the cost of doing research is sufficiently high even when tournament effect is negative.

     

Cooperative vs. non-cooperative R&D incentives under incomplete information

This paper studies incentives for cooperative research vis-à-vis non-cooperative research in an incomplete information framework. We show that with quantity competition under asymmetric information, the expected payoff from non-cooperative research goes down compared to the case of symmetric information; hence research joint venture incentives of the firms are larger under asymmetric information. In either case, however, the larger is the size of the cost-reducing innovation the lower is the incentive for cooperative research. Finally, in our model, incomplete information does not affect the consumers' welfare, but the firms become worse off.
