In a dynamic economy land and capital serve not only as factors of production but as assets which individuals use to transfer income from workinq periods to retirement. Static models of international trade based on the specific-factors model incorporate only the first of these. Once the second...

We introduce quality differentiation and an extensive margin of products into a standard quantitative, general equilibrium model of international trade. Both the quality and the quantity of a product play a role in its contribution both to consumption and to production. The framework allows...

We examine the sales of French manufacturing firms in 113 destinations, including France itself. Several regularities stand out: (1) the number of French firms selling to a market, relative to French market share, increases systematically with market size; (2) sales distributions are very similar...
