Panel Unit Root Tests Under Cross Sectional Dependence
In this paper alternative approaches for testing the unit root hypothesis in panel data are considered. First, a robust version of the Dickey-Fuller t-statistic under contemporaneous correlated errors is suggested. Second, the GLS t-statistic is considered, which is based on the t-statistic of the transformed model. The asymptotic power of both tests against a sequence of local alternatives is ...
متن کاملPanel Unit Root Tests under Cross-sectional Dependence: an Overview
The increasing availability of new datasets where the time-series dimension and the cross-section dimension are of the same order of magnitude asks for new techniques for the analysis of this peculiar kind of data. In the panel unit root test framework, two generations of tests have been developed: a first generation whose main limit is the assumption of cross-sectional independence across unit...
متن کاملHomogenous panel unit root tests under cross sectional dependence: Finite sample modifications and the wild bootstrap
We investigate the performance of some homogenous first and second generation panel unit root tests under alternative forms of cross sectional dependence. We formalize contemporaneous correlation through factor models, spatial autoregressive error models and combinations thereof. Our findings confirm that while the first generation test of Levin, Lin, and Chu (2002) suffers from substantial siz...
متن کاملBootstrap Unit Root Tests in Panels with Cross-Sectional Dependency
We apply bootstrap methodology to unit root tests for dependent panels with N cross-sectional units and T time series observations. More speci cally, we let each panel be driven by a general linear process which may be di erent across crosssectional units, and approximate it by a nite order autoregressive integrated process of order increasing with T . As we allow the dependency among the innov...
متن کاملBootstrap Unit Root Tests
We consider the bootstrap unit root tests based on finite order autoregressive integrated models driven by iid innovations, with or without deterministic time trends. A general methodology is developed to approximate asymptotic distributions for the models driven by integrated time series, and used to obtain asymptotic expansions for the Dickey–Fuller unit root tests. The second-order terms in ...
