In recent years, advances in the field of unit root tests helped topartially solve the first purchasing power parity puzzle. Non-linearmean-reversion tests with real exchange rates were able to reject thenull of a unit root (indicating mean reversion) in significantly morecases than the standard...

Research shows that the predictive ability of economic fundamentals for exchange rates is time-varying; it may be detected in some periods and disappear in others. This paper uses bootstrap-based methods to uncover the time-specific conditioning information for predicting exchange rates....

This research points to the serious problem of potentially misspecified alternative hypotheses when testing for unit roots in real exchange rates. We apply a popular unit root test against nonlinear ESTAR and develop a Markov Switching unit root test. The empirical power of these tests against...

Some recent studies suggest the post-Bretton Woods period offers a sample that is far too short to reveal any significant evidence on purchasing power parity reversion in individual series of real exchange rates. This study shows that the post-Bretton Woods data contain substantial information...

In this paper a likelihood-based multivariate unit root testing framework is utilized to test whether the real exchange rates of G10 countries are non-stationary. The framework uses a likelihood ratio statistic which combines the information across all involved countries while retaining...

This paper examines the PPP hypothesis analysing the behaviour of the real exchange rates vis-à-vis the US dollar for four major currencies (namely, the Canadian dollar, the euro, the Japanese yen and the British pound). An innovative approach based on fractional integration in a multivariate...

The primary purpose of this article is to conduct the Fourier Nonlinear Unit Root Test to check Purchasing Power Parity (PPP) for seven cryptocurrencies traded in seventeen countries from 2010 to 2021. The unit root test provides moderate support to the PPP hypothesis when we use each...

The derivation of the Balassa-Samuelson effect allows for different empirical specifications that may have important economic implications. Problems related to spurious regression could arise from the mixed order of integration of the series used and from the lack of a long run stable...

This study provides quarterly time-series estimates of the misalignment in the REER of the Renminbi (RMB). The estimation is based on a commonly used economic approach, but with a wider and more up-to-date coverage of data and a more extensive use of econometric modelling techniques. Our...

In this paper we analyse the unit root hypothesis when the variable being studied exhibits two changes in its mean. To that end, we design a new statistic which tests for the joint hypothesis that the autoregressive parameter is 1 and that the parameters associated with the structural breaks...
