This paper describes the dynamics of firms' exports to different countries. Using a panel of almost 19,000 French exporters, we define an export-relation as an observed positive export flow from a French firm to a destination. We establish the following facts: 1. There is a great deal of...

Even though differences in sectoral total factor productivity are at the heart of Ricardian trade theory and many models of growth and development, very little is known about their size and their form. In this paper we try to fill this gap by using a Hybrid-Ricardo-Heckscher-Ohlin trade model...

We develop a general equilibrium model of technological change and migration to examine the effects of a change in skill endowments on wages, employment rates and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between skilled and...

What is the relationship between product prices and vertical integration? While the literature has focused on how integration affects prices, this paper provides evidence that prices can affect integration. Many theories in organizational economics and industrial organization posit that...

This paper studies cross-country differences in productivity from an open economy perspective by using a Helpman-Krugman-Heckscher-Ohlin model that embraces the single-cone model and a one-sector economy with factor deepening as particular cases. To estimate the model, I combine tools from...

We develop a model of directed technology adoption, frictional unemployment, and migration to examine the effects of a change in skill endowments on the wages, employment rates, and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution...

We consider a model where exporting requires finding a local partner in each market. Contracts are incomplete and exporters must learn the reliability of their partners through experience. In the model, export behavior is state-dependent due to matching frictions, although there are no sunk...
