In this paper we set up a simple theoretical framework to study thepossible source country effects of skilled labor emigration fromdeveloping countries. We show that for given technologies, labor marketintegration necessarily lowers GDP per capita in a poor source countryof emigration, because...

In this paper we set up a simple theoretical framework to study the possible source country effects of skilled labor emigration. We show that for given technologies, labor market integration necessarily lowers GDP per capita in a poor source country of emigration, because it distorts the...

We set up a general equilibrium model with heterogeneous firms to study the interaction between wage bargaining and foreign direct investment. Thereby, we highlight the incentives of firms to invest abroad in order to improve their bargaining position vis-á-vis local unions and we show how...

This paper documents a robust empirical regularity: in the long-run, higher trade openness is associated with a lower structural rate of unemployment. We establish this fact using: (i) panel data from 20 OECD countries, (ii) cross-sectional data on a larger set of countries. The time structure...

Using data from U.S. commodity flow survey, we show that the historical Union-Confederacy border lowers contemporaneous trade between U.S. states by about 13%. The finding is robust over econometric models, survey waves, or aggregation levels. Including contemporaneous controls, such as network...

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...

Natural disasters affect bilateral trade. We use this fact to generalize the instrumental variables strategy of Frankel and Romer (1999) to a panel setup. This allows revisiting an old question: Does openness cause per capita GDP? We work with a modified gravity framework in which we interact...

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...

We introduce search unemployment into Melitz’s trade model. Firms’ monopoly power on product markets leads to strategic wage bargaining. Solving for the symmetric equilibrium we show that the selection effect of trade influences labor market outcomes. Trade liberalization lowers unemployment...
