Beyond trade costs : firms’ endogenous access to international markets

In this paper, we explore another factor besides trade costs that can affect firms’ exports: strategic interaction between firms in R&D investment. Three results can be highlighted. First, the volume of trade is higher in the presence of R&D than in the absence of it, given that R&D reduces marginal costs. Second, like with reductions in trade costs, international trade grows with increases in the return on R&D, since technological progress enhances firms’ competitiveness. Third, when firms differ in commitment power in R&D, the R&D leader plays strategically in R&D in order to become more competitive and to be more active in international markets than the R&D follower
