Real exchange rate misalignment measures deviations of actual real exchange rate from its long-run, or equilibrium, level. Policy makers and many researchers are interested in predicting and monitoring misalignment in the foreign exchange market, because, in many cases, it is closely related to...

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

In recent years two classes of switching models have been proposed, the Markov switching models, Hamilton (1989) and the Threshold Auto- Regressive Models (TAR), Lim and Tong (1980). These two models have the advantage of being able to modelize and capture asymmetry, sudden changes and...

Using one of the key property of copulas that they remain invariant under an arbitrary monotonous change of variable, we investigate the null hypothesis that the dependence between financial assets can be modeled by the Gaussian copula. We find that most pairs of currencies and pairs of major...

This paper builds on Kočenda (2001) and extends it in two ways. First, two new intervals of the proximity parameter ε (over which the correlation integral is calculated) are specified. For these ε- ranges new critical values for various lengths of the data sets are introduced and through...

This paper extends and generalizes the BDS test presented by Brock, Dechert, Scheinkman, and LeBaron (1996). In doing so it aims to remove the limitation of having to arbitrarily select a proximity parameter by integrating across the correlation integral. The Monte Carlo simulation is used to...

The main objective of this paper is to study the relationship between external public debt and equilibrium real exchange rate in developing countries. Using a extension of Obstfeld & Rogoff (1995) model we show that debt overhang tend to appreciate real exchange rate in the long run (Krugman...

This paper provides evidence of long run purchasing power parity by performing a recently developed method to test for unit roots in the presence of structural breaks. Data consist of real exchange rate series for 20 countries including developed and developing economies. Structural breaks are...

This paper examines the determinants of the real effective exchange rate (REER) in Brazil, from 1994 to 2003. Building on a standard theoretical model and based on the Johansen cointegration estimation, the main finding is that much of the long-run behavior of the REER can be explained by...

We study the behavior of real exchange rates in a two­country dynamic equilibrium model. In this model, consumers can only consume domestic goods but can invest costlessly in capital stocks of both countries. Nevertheless, transporting goods between the two countries is costly and, hence, the...
