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 paper examines factors affecting exchange rate volatility, with an emphasis on structural features of the foreign exchange regime. It draws for the first time on detailed survey data collected by the IMF on foreign exchange market organization and regulations. Key findings are that...

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....

Empirical evidence on the relationship between trade liberalization, exchange rates, and tax revenue is mixed. This paper examines these linkages anew. Using a panel of 22 countries in Sub-Saharan Africa, over 1980-1996, we perform Generalized Method of Moment regressions to test this...

This paper develops a cost-benefit approach that helps to quantify the optimal level of international reserves in low-income countries, focusing on the role of reserves in preventing and mitigating absorption drops triggered by large external shocks. The approach is applied to a sample of 49...

This paper develops a two-country DSGE model to investigate the transmission of a global financial crisis to a small open economy. We find that economies hit by a sudden stop arising from financial distress in the global economy are likely to face a more prolonged crisis than sudden stop...

Does the choice of exchange rate regime affect the way an economy's adjustment to real shocks? Exploiting the randomness of natural shocks, this paper assesses empirically the often contrasting answers found in the theoretical literature. The evidence supports key themes in this literature, and...

The member states of the South Asian Association for Regional Cooperation have set as a target the achievement of an economic union by 2020. Reaching this goal will require greater levels of monetary cooperation. How should this be achieved? Data from South Asia suggest that member states have...

This paper examines the role of Japan against that of China in the exchange rate regime in East Asia in light of growing interest in forming a currency union in the region. The analysis suggests that currency unions with China tend to generate higher average welfare gains for East Asian...

This paper examines the relationship between fixed exchange rate arrangements and trade using a gravity model of international trade together with bilateral trade data from 24 countries from the Caribbean and Latin America for the period 1960-2001. The analysis indicates that a credible fixed...
