This paper focuses on an important empirical and methodological research question, namely possibly asymmetric and hence nonlinear cointegrating relationships between variables. It extends the Granger and Yoon (2002) method on hidden cointegration for time series data to a panel data framework....

Tests for conducting asymmetric Granger causality within a panel system are introduced in this paper. It is shown how the cumulative sums of negative and positive shocks can be constructed to investigate whether the potential causal effects of these shocks are asymmetrical or not within a panel...
