Foreign and Domestic R&D Investment
The authors draw on the technological opportunity, appropriability, and demand framework suggested by Cohen and Klepper (1996) to develop a simple model of foreign and domestic R&D investment. The empirical results confirm that the foreign R&D ratio depends on relative technological opportunities, relative demand conditions, and a proxy for firm-level R&D productivity.
