The belief that immigrants generate beneficial externalities in their host countries, specifically in the form of an increased opportunity and ability of firms to expand their foreign trade, has recently been challenged by George Borjas in Heaven's Door (1999, p. 97) as having no empirical...

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...

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 investigate how fertility and demographic factors affect migration at the household level by assessing the causal effects of sibship size and structure on offspring's international migration. We use a rich demographic survey on the population of Mexico and exploit presumably exogenous...

Linguistic distance, i.e. the dissimilarity between languages, is an important factor influencing international economic transactions such as migration or international trade flows by imposing hurdles for second language acquisition and increasing transaction costs. To measure these costs, we...

The semiconductor industry stands at the center of the intensifying Sino-American trade conflict. Employing a multi-country, multi-sector general equilibrium modeling framework with imperfect competition and heterogeneous firms, we perform qualitative and quantitative analyses of protectionist...

This paper develops an open economy growth model in which firm heterogeneity increases the gains from trade. Technology spillovers from incumbent firms to entrants cause the productivity threshold for firm survival to grow over time as competition becomes tougher. By raising the profits of...

In a two-country international trade model with oligopolistic competition, we study the conditions on market structure and trade costs under which a merger policy designed to benefit domestic consumers is too tough or too lenient from the viewpoint of the foreign country. Calibrating the model...
