Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

In a three-country model of endogenous trade agreements, we study the implications of the Most Favored Nation Clause (MFN) when countries are free to form discriminatory preferential trade agreements (PTAs). While PTA members discriminate against non-member countries, MFN requires non-members to...

This paper is inspired by a puzzling empirical fact that despite the importance of controlling migration for their future, the host countries allocate very limited amounts of resources to the struggle against illegal immigration. The present model analyzes this issue in the context of low...

This paper provides a comprehensive analysis of refugee migration, with emphasis on the current refugee crisis. After first reviewing the institutional framework laid out by the Geneva Convention for Refugees, we demonstrate that, despite numerous attempts at developing a common European asylum...

We analyze the effect of immigrants' legal status on their consumption behavior using unique survey data that samples both documented and undocumented immigrants. To address the problem of sorting into legal status, we propose two alternative identification strategies as exogenous source of...

Between 2014 and 2020 over 1.8 million refugees fled from Venezuela to Colombia as a result of a humanitarian crisis, many of them without a regular migratory status. We study the short- to medium-term labor market impacts in Colombia of the Permiso Temporal de Permanencia program, the largest...

Immigration policies in western democracies have often been contrary to the policies predicted by the mainstream theory of international economics. In particular, political parties that, according to economic theory, should adopt policies beneficial for lower-income voter-constituencies, have...

We develop a general model of legal and illegal immigration to understand the basic tradeoffs faced by a government in the decision to implement an immigration amnesty in the presence of a selective immigration policy. We show that two channels play an important role: an amnesty is more likely...

We combine a model of combined inter-spatial and inter-temporal trade between countries recently used by Huang, Whalley and Zhang (2004) to analyze the merits of trade liberalization in services when goods trade is restricted with a model of foreign exchange rationing due to Clarete and Whalley...
