Short memory models contaminated by level shifts have similar long-memory features as fractionally integrated processes. This makes it hard to verify whether the true data generating process is a pure fractionally integrated process when employing standard estimation methods based on the...

We propose a family of self-normalized CUSUM tests for structural change under long memory. The test statistics apply non-parametric kernel-based fixed-b and fixed-m long-run variance estimators and have well-defined limiting distributions that only depend on the long-memory parameter. A Monte...

We propose a simple test on structural change in long-range dependent time series. It is based on the idea that the test statistic of the standard CUSUM test retains its asymptotic distribution if it is applied to fractionally differenced data. We prove that our approach is asymptotically valid...

It is well known that standard tests for a mean shift are invalid in long-range dependent time series. Therefore, several long memory robust extensions of standard testing principles for a change-in-mean have been proposed in the literature. These can be divided into two groups: those that...

The aim of this work is to propose a new sequential strategy-three steps testing procedure- based on recently introduced econometric techniques, in order to assess the meanreverting properties of the real exchange rate and to check whether real exchange r

This paper examines the hypothesis of Purchasing Power Parity (PPP), i.e. the proposition that the equilibrium real exchange rate is a constant in the long run, in the case of Europe of the 15. For that purpose, we study the statistical properties of 14 European bilateral real exchange rates...

This paper contributes to the permanent income hypothesis (PIH) and excess consumption smoothness debate in the context of fractional integration. We show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in empirical work. In fact,...

This paper investigates the dilemma of long memory versus a switching regime for the Tunisian real exchange rate (TRER). Empirically, three long memory tests are implemented to examine the long-range dependence in the processes of Tunisian REER. All long memory tests that we used are based on...
