of the empirical literature applies ESTAR models and neglects the existence of other competing nonlinear models. Among … literature is fivefold: First, ESTAR and MSAR models from a unit root perspective are compared. To this end, a new unit root test … with real world parameter constellations is studied. The ESTAR unit root test is not indicative, while the MSAR unit test …
