This Paper argues that a geographical perspective is fundamental to understanding comparative economic development in the context of globalization. Central to this view is the role of agglomeration in productivity performance; size and location matter. The tools of the new economic geography are...

Quantitative results from a large class of international trade models depend critically on the elasticity of trade with respect to trade frictions. We develop a simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data using the Ricardian...

This paper proposes a unique overview of trade policies trends since the launch of the Doha Round, based on detailed data on tariffs and trade covering 130 countries. We show that regionalism has delivered limited effective liberalization so far, leading to only a 0.3 percentage point (p.p.) cut...

This paper empirically investigates the effect of the EU-South Korea free trade agreement (FTA) on manufacturing trade flows. By applying a state-of-the-art structural gravity model with intranational (i.e., domestic) trade and using disaggregated data, we quantify both the trade impact and the...

We show that the composition of imports has important implications for the optimal volatility of the exchange rate. Using input-output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported...

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...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

This paper presents a new model of oligopoly in general equilibrium and explores its implications for positive and normative aspects of international trade. Assuming “continuum-Pollak” preferences, the model allows for consistent aggregation over a continuum of sectors, in each of which a...

We examine the gains from Chinese accession to the WTO. Using Arkolakis, Costinot, and Rodríguez-Clare (2012) we provide a new quantitative welfare measure by dividing the manufacturing sector into import and export sub-sectors. We then evaluate how the increased openness caused by China's...

We study the effect of international trade and freeness of trade (openness) on interregional inequality within countries. We estimate a model derived from a structural economic-geography approach in which interregional inequality depends on weighted trade shares and trade costs. In addition to...
