This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodríguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

How do changes in labor market institutions, like more generous unemployment benefits in one country, affect labor market outcomes in other countries? We set up a two-country Armingtonian trade model with frictions on the goods and labor markets. Contrary to the literature, higher labor market...

In the traditional model of international trade, labour market reforms in one country are often viewed as beggar-thy-neighbour policies, because they negatively affect the competitiveness and employment levels of the country’s trading partners. Empirical evidence, however, suggests that this...

The paper sets up a two-country asymmetric trade model with heterogeneous firms, search frictions and endogenous labor market institutions. Countries are linked by trade in goods and non-cooperatively set unemployment benefits to maximize national welfare. We show that more open and smaller...

Multinational enterprises (MNEs) develop their networks of foreign affiliates gradually over time. Instead of exploring all profitable opportunities immediately, they first establish themselves in their home countries and then enter new markets stepwise. We argue that this behavior is driven by...
