In this paper we characterize the set of equilibria in a generalized version of the canonical two-region economic geography model that nests the class of models in Allen and Arkolakis (2014) as well as Krugman (1991). We show that the set of (regular) equilibria corresponds to the set of zeros...

We characterize the set of equilibria in a generalized version of the two-region economic geography model that nests the class of models in Allen and Arkolakis (2014) as well as Krugman (1991). We show that the set of (regular) equilibria corresponds to the set of zeros of a function V(x), where...

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...

"Micro-level data have had a profound influence on research in international trade over the last ten years. In many regards, this research agenda has been very successful. New stylized facts have been uncovered and new trade models have been developed to explain these facts. In this paper we...

"Building on Eaton and Kortum's (2002) model of Ricardian trade, Alvarez and Lucas (2005) calculate that a small country representing 1% of the world's GDP experiences a gain of 41% as it goes from autarky to frictionless trade with the rest of the world. But the gains from openness, which...

This paper quantifies the gains from openness arising from trade and multinational production (MP). We present a model that captures key dimensions of the interaction between these two flows: Trade and MP are competing ways to serve a foreign market; MP relies on imports of intermediate goods...

We explore the implications of models with increasing returns, endogenous variety and firm-level heterogeneity for the quantification of the gains from trade. We first focus on the impact of trade liberalization on imported variety by analyzing the experience of Costa Rica from 1986 to 1992. We...
