The results remain inconclusive as panel stationarity … tests fail to support PPP whereas panel unit root tests fail to reject PPP for the whole sample and for the period before …

Panel unit root tests of real exchange rates - as opposed to univariate tests - usually reject non-stationarity. These … correlation matrix affect the size of first and second generation panel unit root tests. Two components of the real exchange rate …, the real exchange rate of a single good and a weighted sum of relative prices, are constructed from the data for a panel …

One weakness of such tests, however, is that they fail to inform the researcher as … a small number of real exchange rates in a given panel may drive the results. In this paper we examine the PPP … when applied to a set of established panel-unit-root tests, allows the identification of the real exchange rates that are …

The aim of this paper is to apply recently developed panel cointegration techniques proposed by Pedroni (1999, 2004 …

The stationarity of OECD real exchange rates over the period 1972-2008 is tested using a panel of twenty six member … countries. The methodology followed stems from the need to meet several key concerns: (i) the identification of which panel … members are stationary; (ii) the presence of cross-sectional dependence among the countries in the panel; and (iii) the …

In this paper we show the consequences of applying a panel unit root test when testing for a purchasing power parity …

In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The … industrialized countries. In some cases seasonal unit roots are detected. However, the null hypotheses of panel seasonal unit roots …

This paper re-assesses the panel (unit root test) evidence for PPP on four monthly data sets.
