Abstract

This study explores the effects of R&D subsidies in a hybrid growth model in which the economy may exhibit semi-endogenous growth or fully endogenous growth. We consider two types of R&D subsidies on variety-expanding innovation and quality-improving innovation. R&D subsidies on quality-improving innovation only have effects in the fully-endogenous-growth regime, in which a higher subsidy rate leads to an earlier activation of quality-improving innovation and increases the transitional and steady-state growth rate. R&D subsidies on variety-expanding innovation have contrasting effects in the two regimes. In the semi-endogenous-growth regime, a higher subsidy rate on variety-expanding innovation increases transitional growth but has no effect on steady-state growth. In the fully-endogenous-growth regime, a higher subsidy rate on variety-expanding innovation continues to increase short-run growth but delays the activation of quality-improving innovation and reduces long-run growth. Increasing R&D subsidies on variety-expanding (quality-improving) innovation makes the semi-endogenous-growth (fully-endogenous-growth) regime more likely to emerge in equilibrium.
