The Impact of Foreign Direct Investment on Home and Host Countries with Endogenous R&D.

he paper analyzes the impact of FDI on home and host countries, when firms compete both in the choice of international strategy and in R&D. A two-country, two-firm model is used. The problem is structured as a three-stage game in which firms must decide: the mode of foreign expansion; how much to invest in R&D; how much to sell in each market. It is shown that in high-technology sectors a policy of attracting inward FDI may increase welfare in both the home and host countries. The effect on host-country welfare is found to be more beneficial if technological spillovers are national, instead of international, in scope. Copyright 2002 by Blackwell Publishing Ltd.
