Resumen de Purchasing power parity in central and eastern european countries: an analysis of unit roots and nonlinearities
The aim of this paper is to analyse the empirical fulfilment of PPP in a number of Central and Eastern European countries. For this purpose we apply two different unit root tests in order to control for two sources of nonlinearities, i.e. Bierens (1997) and Kapetanios, Shin and Snell (2003). We find that PPP holds in most of these countries once account has been taken of nonlinear deterministic trends and smooth transitions.
