The Global Diffusion of Ideas

Ezra Oberfield and Francisco Buera

No 1538, 2016 Meeting Papers from Society for Economic Dynamics

Abstract: We provide a tractable theory of innovation and technology diffusion to explore the role of international trade in the process of development. We model innovation and diffusion as a process involving the combination of new ideas with insights from other industries or countries. We provide conditions under which each country’s equilibrium frontier of knowledge converges to a Frechet distribution, and derive a system of differ- ential equations describing the evolution of the scale parameters of these distributions, i.e., countries’ stocks of knowledge. In particular, the growth of a country’s stock of knowledge depends only on its trade shares and the stocks of knowledge of its trading partners. We use the framework to quantify the contribution of bilateral trade costs to cross-sectional TFP differences, long-run changes in TFP, and individual post-war growth miracles.
