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...

Is the recent proliferation of Regional Trade Agreements (RTAs) in Asia a healthy development, or runs the risk of turning into an unmanageable "noodle bowl" in the future? The goal of this paper is to shed some light on this question. The results show that membership in the Asian RTAs...

Regional trade arrangements (RTAs) in Africa have been ineffective in promoting trade and foreign direct investment. Relatively high external trade barriers and low resource complementarity between member countries limit both intra- and extraregional trade. Small market size, poor transport...

Preferential trade agreements (PTAs) in the Asia-Pacific region have proliferated rapidly over the past five years and are creating a complex web of intersecting bilateral and regional trade agreements. This paper describes the proliferation of these PTAs, discusses their characteristics and...

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...

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....

Current U.S. trade policy stresses establishing free trade areas (FTAs) with partners spanning the globe. Motivations include enhancing goods and services trade; stimulating investment flows; extending standards on intellectual property rights, labor, and the environment; and addressing...

This paper analyzes the appropriate sequencing between accession to the World Trade Organization (WTO) and the implementation of the Eurasian Economic Community (EAEC) customs union and whether the latter facilitates or delays WTO accession for some member countries of the Commonwealth of...

This paper estimates a gravity model to address the issue of whether intra-Arab trade is too little. Although gravity models have been extensively used to measure bilateral trade among countries, they have—to the best of our knowledge—never been used to measure intra-Arab trade. Our results...

South-South trade agreements are proliferating: Developing countries signed 70 new agreements between 1990 and 2003. Yet the impact of these agreements is largely unknown. This paper focuses on the static effects of South-South preferential trade agreements stemming from changes in trade...
