The Asymptotic Distribution of the CADF Unit Root Test in the Presence of Heterogeneous AR(p) Errors
(2016) In Statistical Papers 57(2). p.303-317- Abstract
- The CADF test of Pesaran (A Simple Panel Unit Root Test in Presence of Cross-Section
Dependence, Journal of Applied Econometrics 22, 265–312, 2007) are among the most popular
univariate tests for cross-section correlated panels around. Yet, the existing asymptotic
analysis of this test statistic is limited to a model in which the errors are assumed to
follow a simple AR(1) structure with homogenous autoregressive coefficients. One reason
for this is that the model involves an intricate identification issue, as both the serial
and cross-section correlation structures of the errors are unobserved. The purpose of the
current paper is to tackle this issue and in so doing extend the... (More) - The CADF test of Pesaran (A Simple Panel Unit Root Test in Presence of Cross-Section
