Abstract:This paper studies the dynamic evolution ofthe patterns of Ricardian comparative advantagefrom the perspective of knowledge diffusion. Thetheoretical analysis builds knowledge diffusioninto a quantifiable model of trade by allowing forindustry-level productivity to evolve through aspatial flow of ideas.This theoretical frameworkyields a law of motion of industry-levelproductivity across countries,capturing stronginterdependence in the evolution of Ricardiancomparative advantage. We calibrate the modelto78economies and15manufacturingindustries,spanning from 1991 to 2017. Ourquantitativeframeworkcapturesstrongconvergence in industry-level productivity andfacilitates the identification of the key playersthat contribute most to global productivitygrowth. We use our model to draw a rich set ofquantitative implications，including a welfareanalysis of targeted restrictions of technologytrade.
