We provide an analysis of the 2008-2009 trade collapse using microdata from a small open economy, Belgium. First, we find that changes in firm-country-product exports and imports occurred mostly at the intensive margin: the number of firms, the average number of destination and origin markets...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

Knowledge is key to the success of a firm. Firms and their managers acquire knowledge via channels which are often difficult to track down and quantify. By matching employer-employee data with trade data at the firm level we show that the export experience acquired by managers in previous firms...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

We develop a new general equilibrium monopolistic competition model with variable demand elasticity, heterogeneous firms, and multiple asymmetric regions. Wages, productivity, consumption diversity, and markups across firms and markets are all endogenously determined and respond to trade...
