We propose a nonlinear heterogeneous unit root test for testing the null hypothesis of unitroots processes against the alternative that allows a proportion of units to be generated by globally stationary ESTAR processes and a remaining non-zero proportion to be generated by unit root processes. The proposed test is simple to apply and accommodates cross sectional dependence. Monte Carlo simulation shows that our test holds correct size and under the hypothesis that data are generated by globally stationary ESTAR processes has a better power than the recent test proposed in Pesaran (2005).An application to a panel of bilateral real exchange rate series with the US Dollar from the 11 major OECD countries is provided.
