This paper investigates the importance of real exchange rates on export volumes by estimating a panel SVAR model using quarterly unbalanced panel data from 21 emerging markets over the 2005:Q1-2018:Q4 period. Although the results suggest no conclusive evidence that real exchange rate shocks do...

This paper examines the real exchange rate's (REER) response to the real GDP, FDI, M2, trade openness (OPEM), foreign reserves (FER) and government expenditure(GE) for Korea and China. The analyses are based on the VECM and NATREX models. In short run for China, we find that RGDP, FER and GE...

This paper investigates the validity of purchasing power parity (PPP) for 25 OECD countries by using a panel unit-root methodology. The procedure used here is to examine stationarity of real exchange rate. Using ADF unit-root test on single time-series, it is found that real exchange rate of all...

The rate of mean-reversion in a country's real exchange rate (RER) is a key indicator to consider when discussing exchange rate policies in any country. In practice, this rate - known as the half-life - is commonly calculated using price aggregates, such as the consumer price index (CPI). I...

This study examines the validity of the Purchasing Power Parity (PPP) in four Arab countries that recently experienced political instability, those being Syria, Egypt, Tunisia, and Bahrain. Using monthly data of the real effective exchange rates (REER) of the countries in question from 1995 to...

We test the validity of Purchasing Power Parity theory, examining the Real Exchange Rate of 23 OECD countries for mean-reversion. In doing so, we estimate the Hurst exponent which is a well-established estimator of long memory in time series analysis. The innovation of our approach is that we...

This paper seeks to estimate the long run behavioral equilibrium real exchange rate in Nigeria. The econometric analysis starts by analyzing the stochastic properties of the data and subsequently estimates a vector error correction model. Regression results show that most of the long-run...

This paper investigates whether the real oil price has an impact on the real exchange rates of three main oil-exporting countries: Norway, Russia and Saudi Arabia. We create our measure of the real effective exchange rates for Norway and Saudi Arabia (1980-2006) and for Russia (1995-2006),...

Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we...

This paper introduces a time-varying threshold autoregressive model (TVTAR), which is used to examine the persistence of deviations from PPP. We find support for the stationary TVTAR against the unit root hypothesis; however, for some developing countries, we do not reject the TVTAR with a unit...
