Survey on structural breaks and unit root tests
Anton Skrobotov ()
Applied Econometrics, 2020, vol. 58, 96-141
his review discusses methods of testing for a unit root in a time series in the presence of structural breaks. Separately the methods for break date estimation under uncertainty over the order of integration are considered. The review covers a large number of recently developed testing methods that are robust to various types of data uncertainty, including initial conditions and time-varying volatility. The survey introduces the reader to practical application of modern testing methods together with an understanding of the development of these methods.
Keywords: unit root testing; structural breaks; stationarity testing; non-stationary volatility; robust methods. (search for similar items in EconPapers)
