摘要： We develop a quantifiable multi-country, multi-sector endogenous growth model in which comparative advantage is endogenously determined by innovation and knowledge diffusion. We quantify the effect of a trade liberalization on innovation, comparative advantage and welfare. Changes in trade frictions reallocate innovation and comparative advantage across sectors: innovation reallocates towards sectors with larger increases in comparative advantage, and comparative advantage reallocates towards sectors with stronger knowledge spillovers. Knowledge spillovers amplify the effect as countries and sectors benefit from technology developed elsewhere. In contrast to one-sector models without knowledge spillovers, we find significant dynamic gains from trade, driven by innovation and diffusion.
