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...

A deranged publisher decided to produce a volume of some of my papers and asked me to write some comments. Since these amount to a summary of my views about international trade theory over the latest forty years or so, I'm giving the comments a separate alternative existence as a discussion paper

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

In this paper, we investigate the mechanisms through which import tariffs impact the macroeconomy in two large scale workhorse models used for quantitative policy analysis: a computational general equilibrium (CGE) model (Purdue University GTAP model) and a multi-country dynamic stochastic...

Quantifying the effects of trade policy in the age of "global value chains" (GVCs) requires an enhanced analytical framework that takes the observed international input-output relations in due account. However, existing quantitative general equilibrium models generally assume that industry-level...

General equilibrium model of international trade has profoundly impacted various sub-disciplines of economics such as development economics, public economics, and environmental economics, among many others. These models continue to inspire younger generations of researchers and are used as...

We set up two rival Computable General Equilibrium (CGE) models of world trade, one based on classical theories of comparative advantage, the other based on recent gravity theories. We have tested them by indirect inference on the time-series of trade facts for five major countries or country...

In this study, we investigate three trade policy scenarios: i) the revival of multilateralism, ii) plurilateral cooperation, and iii) geopolitical rivalry. In the first scenario, both tariffs and NTMs are reduced on a multilateral basis. In the second scenario, varying groups of countries...

Madagascar plans to start phasing out its customs tariffs on imports from the Southern African Development Community in 2007. This paper uses a CGE model to evaluate the impact of the SADC FTA on Madagascar economy. The results suggest that the SADC FTA would only have a limited impact on...

This paper uses a structural gravity model to explore the regional trade and welfare impact of the EU Cohesion Policy Transport Infrastructure Investment programme estimated using a novel data-set of the Generalised Transport Costs for the EU regions at the NUTS2 level. The results indicate that...
