presence of incidental trends in panel unit root test setting is ubiquitous. …

asymptotically normal (LAN) experiments with the same central sequence and Fisher information. Using Le Cam’s theory of statistical …

. For these purposes, panel unit root tests are employed to improve power against univariate counterparts. Since cross … section correlation is a distinct feature of the underlying panel data, results are based on various second generation panel …

useful way of summarizing the persistence in a panel data set, as well as a complement to more traditional panel unit root …

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 …

We consider large n, T panel data models with fixed effects, persistent common factors allowing for cross …

We derive the power envelope for panel unit root tests where heterogeneous alternatives are modeled via zero …

Applying the new panel unit root test developed in this paper, we can overcome the pitfalls of old-fashioned panel unit …-Fuller and traditional panel data unit root test, however, when using the new test developed in this paper we find strong …
