unit root tests are examined in the presence of generalised autoregressive conditional heteroskedasticity (GARCH). It is …–Fuller unit root test when applied to series exhibiting GARCH. Importantly, it is found that the use of consistent … the GARCH model. The relevance of the simulation analysis conducted is supported by GARCH modelling of the term structure …

The purpose of this paper is to investigate the asymptotic null distribution of stationarity and nonstationarity tests when the distribution of the error term belongs to the normal domain of attraction of a stable law in any finite sample but the error term is an i.i.d. process with finite...

The standard Dickey–Fuller (DF) test is routinely employed to analyse the integrated nature of economic and financial time series. However, recent research has shown the test to suffer severe size distortion in the presence of breaks in innovation variance under the unit root null hypothesis....
