Quantifying the welfare effects of trade liberalization is a core issue in international trade. Existing frameworks assume perfect labor markets and therefore ignore the effects of aggregate employment changes for welfare. We develop a quantitative trade framework which explicitly models labor...

This paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the...

We study the performance of the four Western Hemisphere trading blocs during the period 1978-2001. For the North American Free Trade Agreement (NAFTA), trade integration outweighed trade diversion; for MERCOSUR, increased integration and trade diversion went hand in hand; for the Central American...

This paper provides a framework for understanding trade patterns in the Mashreq. An augmented gravity model is used to compare actual with expected levels of trade. Trade barriers, political uncertainty, and over-appreciation of domestic currencies seem to explain low levels of international...

Using firm-level data for Estonia for the years 1997-2005, we analyze the impact of international competition on firm dynamics, considering both firm closedown and product switching. We contribute to the literature in two important ways: (1) this is the first paper to study the determinants of...

This paper investigates whether a regional bloc would enlarge or remain stagnant in size using a model where enlargement is the endogenous outcome of the interaction between the supply of and demand for membership. We show that a maximum size of the bloc exists beyond which the regional...

Trade theories covering Preferential Trade Agreements (PTAs) are as diverse as the literature in search of their empirical support. To account for the model uncertainty that surrounds the validity of the competing PTA theories, we introduce Bayesian Model Averaging (BMA) to the PTA literature....

Gravity models of international trade have been frequently applied to estimate the impact of common (official or spoken) language on bilateral trade. This study provides a meta-analysis based on 701 language effects collected from 81 academic articles. On average, a common (official or spoken)...
