In this study we apply flexible Fourier stationarity unit root testing as proposed by Enders and Lee (2004, 2009) to assess the nonstationary properties of per capita real gross domestic product (GDP) for nine central and east European (CEE) countries. We find that the Fourier stationary unit...

This study applies nonlinear cointegration to assess exchange rates with the corresponding relative prices and aggregate price levels for seven Central and East European countries (CEECs). We find that nonparametric rank testing procedures have higher power than parametric testing procedures, as...
