How large are welfare costs related to economic aggregate fluctuations is a topic of great concern among economists at least since Robert Lucas’ well-known and thoughtprovoking exercise in the late 1980s. Our analysis assesses the magnitude of such costs for 11 countries in South America...

The inability of a wide array of dynamic stochastic general equilibrium (DSGE) models to generate fluctuations that resemble actual business cycles has lead to the use of habit formation in consumption. For example, habit formation has been shown to help explain the negative response of labour...

The September 11, 2001 terrorist attack to the twin towers and ensuing heightened national security measures worldwide, but particularly in the United States, are modeled to be equivalent to a thickening of trade barriers in international trade. By estimating a gravity model with a stochastic...

This paper examines the issue of sustaining free trade when countries receive imperfect private information about each other’s non-tariff barriers. Because the countries can misrepresent their private belief about other countries’ protection levels, the punishment scheme to deter...

Abstract: The paper analyzes cyclical comovements in the Mercosur area differentiating idiosyncratic from common shocks. In the Mercosur (or any region for that matter) shocks can be country-specific, affecting only one country or a specific set of countries (for example, a weather-related...

Since the seminal work of Krugman (1979), product variety has played a central role in models of trade and growth. In spite of the general use of love-of-variety models, there has been no systematic study of how the import of new varieties has contributed to national welfare gains in the United...

This paper shows how the institutional rules imposed on its signatories by the GATT created a strategic incentive for countries to liberalize gradually. Free trade can never be achieved if punishment for deviation from a trade agreement is limited to a 'withdrawal of equivalent concessions.'...

This paper examines the effects that capital inflows have on the financial system in a Diamond-Dybvig environment. Here, an adverse-selection problem arises where short-term capital has the incentive to enter the domestic banking system while long-term capital chooses to stay out. Then,...

This paper investigates whether the presence of financial frictions can help explain the differences in the variability of output and inflation between the Pre- and the Post-Volcker periods. I use a limited participation model with credit market imperfections, in which financial frictions may...

This paper examines linkage of real interest rates for a group of selected countries in East Asia. The countries under study include Japan, Korea, Singapore, Malaysia and Thailand. The long run relationship is tested and estimated using the conitegration analysis. We also have conducted the...
