This paper provides a general equilibrium analysis of the trade effects of the formation of a currency union, and of its subsequent enlargement to include an economically dissimilar country. Furthermore, it investigates how economic dissimilarities among countries affect the magnitude of the...

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...

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....

This paper provides an overview of trade reform in the West African Economic and Monetary Union (WAEMU) since 1996 and a quantitative assessment of potential effects on trade patterns and tariff revenue of the current reform agenda. Despite evidence of significant trade complementarities within...

What determines the currency to which countries peg or "anchor" their exchange rate? Data for over 100 countries between 1980 and 1998 reveal that trade network externalities are a key determinant. This implies that anchor currency choice may well be suboptimal in that certain currencies, e.g.,...

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...

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...

The recent experience of the European Economic and Monetary Union (EMU) has stimulated the debate over currency union and reinforced the incentive for the emergence of currency blocs in other regions of the world. This paper builds a dynamic stochastic model-based on network externalities...
