We analyze the sources of macroeconomic fluctuations in the emerging countries in the Middle East and North Africa (MENA) region using a dynamic stochastic general equilibrium model. The model economy captures some important structural characteristics of the MENA countries and can replicate the...

During currency crises, some currencies depreciate more than the post-crisis exchange rate level, which can be described as exchange rate overshooting. Previous studies have claimed that a tight monetary policy, represented by an increase in the interest rate, stabilizes an exchange rate by...

This paper studies optimal tax policy problem by employing a two-country dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare-improving active, contingent tax policies (under which tax rates respond to changes in productivity) on capital and...

This paper examines the dynamic implications of the use of an endogenous discount factor in small open economy models. We first present a stochastic dynamic model of a small open economy with an endogenous discount factor. Then, we examine the same model with a fixed discount factor. We...

Papers on international business cycles have documented spurious welfare reversals: incomplete markets produce a higher level of welfare than the complete market. This paper first demonstrates how conventional linearization, as used in King, Plosser, and Rebelo (1988), can generate approximation...

In this paper, we investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. In particular, we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only...

This paper studies an international tax policy design problem by employing a two-country dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare improving active tax policies, in particular capital and labor income tax, under the non-cooperative...
