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 …

Missing data or missing values are a common phenomenon in applied panel data research and of great interest for panel … data unit root testing. The standard approach in the literature is to balance the panel by removing units and/or trimming a … common time period for all units. However, this approach can be costly in terms of lost information. Instead, existing panel …
