Growth and innovation policy in a small, open economy: Should you stimulate domestic R&D or exports?

Abstract

In small and open economies, absorption of foreign knowledge through international trade often plays a more important role for domestic innovation and growth than investment in domestic R&D. This suggests that trade policies can increase knowledge spillovers from abroad. Public support to R&D can be motivated both by positive internal knowledge externalities and by its ability to expand absorptive capacity. This dynamic, empirical, general equilibrium analysis models these interplays between R&D, trade and productivity. It compares public R&D support and export promotion of R&D based products with respect to long term growth and welfare impacts. We find that export promotion is inferior to R&D support in spurring R&D. However, it is not outperformed in terms of welfare generation. The reason is that existing and politically persistent policy interventions create inefficiencies that can be counteracted by R&D-based export promotion as a second-best policy.
