Data on the individual export destinations of French firms shed light on the nature of entry barriers to national markets. The data reveal some striking regularities: (1) Looking across des tinations, the relationship between market size, French market share, and the number of French firms...

We incorporate trade imbalances into a quantitative model of bilateral trade in manufactures, dividing the world into forty countries. Fitting the model to 2004 data on GDP and bilateral trade we calculate how relative wages, real wages, and welfare would differ in a counterfactual world with...

We use a forty-two country model of production and trade to assess the implications of eliminating current account imbalances for relative wages, relative GDP's, real wages, and real absorption. How much relative GDP's need to change depends on flexibility of two forms: factor mobility and the...

This paper uses a 42-country model of production and trade to assess the implications of eliminating current account imbalances for relative wages, relative GDPs, real wages, and real absorption. How much relative GDPs need to change depends on flexibility of two forms: factor mobility and...

We consider the interaction of trade and technology diffusion in a two-region model of innovation and imitation. We find that globalization, either in the form of lower trade barriers or in faster diffusion of technology between innovator and imitator spurs innovation, benefiting both regions.

We model the invention of new technologies and their diffusion across countries. In our model all countries grow at the same steady-state rate, with each country's productivity ranking determined by how rapidly it adopts ideas. Research effort is determined by how much ideas earn at home and...
