A simple semi-endogenous growth model is employed to show that optimal subsidization of both R&D and capital costs is independent of the distribution of R&D skills in the workforce. This holds despite the empirically supported fact that a higher R&D subsidy rate raises wages of R&D workers.

This paper argues that growth theory needs a more general notion of "regularity" than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set of...
