We analyze the possibility of nonlinear adjustment and unknown smooth breaks in the stationarity of real exchange rates in the Group of 20 (G-20) countries over a period from January 1994 to April 2010 by applying the Panel SURADF test with Fourier function. Although most of the results from a...

The aim of this paper is to provide additional evidence on the purchasing power parity empirical fulfilment in a pool of OECD countries. We apply the Harvey et al. (2008) linearity test and the Kruse (2011) nonlinear unit root test. The results point to the fact that the purchasing power parity...

A unique panel of retail prices spanning 123 cities in 79 countries from 1990 to 2005 is used to uncover the novel properties of long-run international price dispersion. At the PPP level, almost all of price dispersion is attributed to unskilled wage dispersion. At the level of individual goods...

Im et al. (Unpublished working paper, <CitationRef CitationID="CR11">2008</CitationRef>) develop cointegration tests using stationary instrumental variables. Their tests avoid the need to simulate critical values for the cointegration estimations, especially problematic in the presence of a nuisance parameter. Likewise, bootstrapping...</citationref>

This paper examines mean reversion in real effective exchange rates in six leading Latin American economies during the XXth century using a new data set. A unit-root approach is complemented by an error-correction model including key fundamentals such as terms of trade, trade openness and...

This paper uses a unique new monthly US-UK real exchange rate series for the January 1794 – December 2009 period to reexamine the academic debate over purchasing power parity (PPP). The consensus view described by Rogoff (1996) is that PPP holds in the long-run, but short run deviations are...

We use consumer price data for 81 European cities (in Germany, Austria, Finland, Italy, Spain, Portugal and Switzerland) to study the impact of the introduction of the euro on goods market integration. Employing both aggregated and disaggregated consumer price index (CPI) data we confirm...

Real exchange rates are quite persistent. Standard unit root tests are not very powerful in drawing a conclusion regarding the validity of purchasing power parity [PPP]. Rather than asking if PPP holds throughout the whole sample period, we examine if PPP holds sometimes by employing...

In this study, we employ that panel unit root tests can be arranged in groups by cross-section dependence or independence, heterogeneous or homogenous unit roots to examine the validity of the purchasing power parity (PPP) hypothesis in Turkey, among trading partners. Using monthly observations...

This paper tests for PPP in a group of seventeen Latin American (LA) countries by applying fractional integration techniques to real exchange rate series. Compared to earlier studies on these economies, this approach has the advantage of allowing for non-integer values for the degree of...
