Abstract: The aim of this paper is to analyse the empirical fulfilment of the PPP in Australia (1977-2004). Previous research focuses on the presence of structural breaks and fails to find any support to the PPP (Darne and Hoarau, 2008, Henry and Olekalns, 2002). In contrast, we find that the PPP hypothesis holds once we account for a more general specification of the Nonlinear Deterministic components based on a Chebishev polynomials approximation.
