This paper demonstrates that unit root tests can suffer from inflated Type I error rates when data are cointegrated. Results from Monte Carlo simulations show that three commonly used unit root tests - the ADF, Phillips-Perron, and DF-GLS tests - frequently overreject the true null of a unit...

In this paper, we develop new threshold cointegration tests with SETAR and MTAR adjustment allowing for the presence of … breakpoint and test the null hypothesis of no cointegration. Thereby, we extend the well-known residual-based cointegration test … Carlo experiments. We find a substantial decrease of power of the conventional threshold cointegration tests caused by a …
