Trade liberalization, competition and growth

The aim of this paper is to understand whether international trade may enhance innovation and growth through an increase in competition. We develop a twocountry endogenous growth model, both countries producing the same set of goods, with firm specific R&D and a continuum of oligopolistic sectors under Cournot competition. Since countries produce the same set of goods, trade openness makes markets more competitive, reducing prices and raising the incentives to innovate. More general, a reduction on trade barriers enhances growth by reducing domestic firms`market power.
