Using a novel panel data set of Japanese inventors, we investigate how monetary incentives affect corporate inventors' behavior and performance. Furthermore, we analyze how these incentives interact with intrinsic motivation. Our findings are as follows: (1) While introducing or raising revenue-based payments is associated with higher patent quality, such schemes decrease the number of citations to non-patent literature; (2) the strength of intrinsic motivation - measured by the importance of the inventors’ interest in contributing to the advancement of science (“taste for science” hereafter) - raises the inventors' patent productivity; and (3) the taste for science weakens the marginal effect of monetary incentives on inventive productivity, and further reinforces the negative effect of monetary incentives on the inventors’ backward citations from non-patent literature.
