We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

This paper assesses the quantitative importance of including sectoral heterogeneity in computing the gains from trade. Our framework draws from Caliendo and Parro (2015) and Alvarez and Lucas (2007) and has sectoral heterogeneity along five dimensions, including the elasticity of trade to trade...

What has been the overall global welfare impact of the accession to the World Trade Organization of a large country like China, or the global welfare impact of the completion of the Uruguay round of GATT negotiations? Can we come up with a simple user-friendly formula to calculate the global...

We show that multilateral tariff binding liberalization substantially impacts the nature and extent of Preferential Trade Agreement (PTA) formation. First, it shapes the nature of forces constraining expansion of Free Trade Agreements (FTAs). The constraining force is a free riding incentive of...

This paper investigates both aggregate and distributional impacts of the trade integration of China, India, and Central and Eastern Europe in a quantitative multi-country multi-sector model, comparing outcomes with and without factor market frictions. Under perfect within-country factor...

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...

PTAs are generally negotiated without any tariff concessions or transfers to non-member countries. Can such a PTA benefit the neighbors’ welfare? In a two-good competitive equilibrium model in the absence of an entrepôt, a PTA without concessions to the outside will hurt the outsider’s...

Globalization disrupted the seemingly solid construction emerged in the aftermath of WW II, called the international trade system. For over fifty years, the system grew constantly thanks to the increasing number of countries that joint it as well as to its ubiquitously-accepted rules. For better...
