In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The … industrialized countries. In some cases seasonal unit roots are detected. However, the null hypotheses of panel seasonal unit roots …

. 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 …

This paper studies subsampling hypothesis tests for panel data that may be nonstationary, cross-sectionally correlated … the tests without estimating nuisance parameters. The tests include panel unit root and cointegration tests as special … shown that subsampling provides asymptotic distributions that are equivalent to the asymptotic distributions of the panel …

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

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 …

This paper investigates the validity of purchasing power parity (PPP) for 25 OECD countries by using a panel unit … by the combination of the time-series and cross-sectional data and the subsequent power advantages of panel data unit …
