The study examines whether the long-run validity of PPP holds in some major advanced and developing economies. The study employed the smooth time-varying cointegration (TVC) and time-varying detrended fluctuation analysis (DFA) methodology, and we are not aware of any study that has applied TVC...

We examine the mean-reverting properties of real exchange rates, by comparing the unit root properties of a group of international real exchange rates with two groups of intra-national real exchange rates. Strikingly, we find that while the international real rates taken as a group appear...

The aim of this paper is to provide evidence about the existence or non-existence of structural breaks in exchange rates of European transition economies. We used the testing procedure of Vogelsang (1997) that allows for detecting a break at an unknown date in the trend function of a dynamic...

This paper attempts to model the nominal and real exchange rate for Ireland, relative to Germany and the UK from 1975 to 2003. It offers an overview of the theory of purchasing power parity (Ppp), focusing particularly on likely sources of nonlinearity. Potential difficulties in placing the...

In this study the long-run relationship between real oil price, real effective exchange rate and productivity differentials is examined using annual data for Nigeria over the period 1980 to 2010. We aim to investigate whether oil price fluctuations and productivity differentials affect the real...

Deciding whether a time series that appears nonstationary is in fact fractionally integrated or subject to structural change is a diffcult task. However, various tests have recently been introduced for distinguishing long memory from level shifts and nonlinearity. In this paper, three testing...

In contrast with the large literature that studies the interactions between the oil and the foreign exchange (FX) markets at the return level, this paper examines their relationship at the risk level. We employ the multivariate stochastic volatility (MSV) and the multivariate conditional...

We investigate the persistence of real exchange rates using Bayesian methods. First, an algorithm for Bayesian estimation of nonlinear threshold models is developed. Unlike standard grid-based estimation, the Bayesian approach fully captures joint parameter uncertainty and uncertainty about...

In this paper we evaluate a set of Colombian exchange rate forecasts during 1995-2005, using a Purchasing Power of Parity Exchange Rate Model (PPPER). Our first finding is that the computed forecasts seem to validate the use of this model under certain conditions given that, theoretically, it...

Starting from Obaseki (1998), several authors have developed different models of Naira equilibrium real exchange rate in a bid to better understand its behavior, albeit without accounting for the possibility and effects of structural breaks in their models. This is counterintuitive, especially...
