The Global Diffusion of Ideas and Its Impact on Productivity and Growth
Economic growth often comes hand in hand with the growth of trade. However, according to quantitative models that rely on standard static mechanisms, the gains from trade are fairly small. This article introduces a model to study the diffusion of ideas across countries as a means of increasing productivity and provides a quantitative assessment of the role of trade in the transmission of knowledge.

Markets, Externalities, and the Dynamic Gains of Openness
Inflows of foreign knowledge are the key for developing countries to catch up with the world technology frontier. In this paper, I construct a simple tractable model to analyze (a) the incentives of foreign firms to bring their know-how to a developing country and (b) the incentives of domestic firms to invest in their own know-how, given the exposure to foreign ideas and competition. The model embeds two diffusion mechanisms typically considered separately in the literature: externalities and markets. The dynamic gains of openness can be substantial under either mechanism, but their relative ...

Technology Diffusion: The Case of Internet Banking
Taking internet banking as an example, we study diffusion of cost-saving technological innovations. We show that the diffusion of internet banking follows an S-shaped logistic curve as it penetrates a log-logistic bank-size distribution. We test the theoretical hypothesis with an empirical study of internet banking diffusion among banks across fifty U.S. states. Using an instrument-variable approach, we estimate the positive effect of average bank size on internet banking diffusion. The empirical findings allow us to examine the technological, economic, and institutional factors governing the ...
