Abstract

We distinguish non-normality from non-linearity in G7 real exchange rate dynamics by correcting the critical values of the Kapetanios et al. [Kapetanios, G., Shin, Y., Snell, A., 2003. Testing for a unit root in the non-linear STAR framework. Journal of Econometrics, 112, 359-379] test for non-normality using the wild bootstrap. Our findings validate non-linear Purchasing Power Parity net of non-normality effects.
