It is commonly believed that spillover reduces R&D incentives of a firm. This happens because of the non-appropriability problem. However, some empirical literature shows the possibility of enhanced R&D incentives under spillovers. While this is explained in the literature under incomplete information, we show that this may hold even under complete information. We show in particular that in a duopoly there are situations when with no spillovers only one firm invests in R&D, but under spillovers both the firms invest. This occurs when there is complementarity in research and the spillover is below a critical level.
