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...

International competitiveness is often regarded as crucial for the attainment of gains from trade, which may lead policy makers to subsidize exports. This view is based on confusion between the concepts of competitive and comparative advantage. The paper argues that when comparative advantage is...

How does import protection affect export performance? In trade models with scale economies, import liberalization can reduce industry-level exports by cutting domestic production. We show that this export destruction mechanism reduced US export growth following the permanent normalization of...

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

We study empirically and theoretically the growth of U.S. manufacturing exports from 1987 to 2007. We identify the change in iceberg costs with plant-level data on the intensity of exporting by exporters. Given this change in iceberg costs, we find that a GE model with heterogeneous...

The business literature and recent descriptive evidence show that exporting firms typically require the help of foreign trade intermediaries or need to set up own foreign wholesale affiliates. In contrast, conventional trade theory models assume that producers can directly access foreign...

In times of increasing oil prices and a weak dollar, European companies that focus their business on the US market may find themselves in a weak position. While many businesses can hedge this kind of risk by relocating production to the US, or employing financial remedies, these strategies may...

We study how financial frictions affect firm-level heterogeneity and trade. We build a model where productivity differences across monopolistically competitive firms are endogenous and depend on investment decisions at the entry stage. By increasing entry costs, financial frictions lower the...

In times of increasing oil prices and a weak dollar, European companies that focus their business on the US market may find themselves in a weak position. While many businesses can hedge this kind of risk by relocating production to the US, or employing financial remedies, these strategies may...
