In this paper we present a unit root test against a nonlinear dynamic heterogenous panel with each cross section …

In this paper we derive a unit root test against a Panel Logistic Smooth Transition Autoregressive (PLSTAR). The …, finite sample properties of the test are examined. We highlight scenarios under which the traditional panel unit root tests … by Harris and Tzavalis have inferior or reasonable power compared to our test. -- Dynamic nonlinear panel ; Smooth …
