Unit Root Testing against the Alternative Hypothesis of up to m Structural Breaks

George Kapetanios

No 469, Working Papers from Queen Mary University of London, School of Economics and Finance

Abstract: In this paper we provide tests for the unit root hypothesis against the occurence of an unspecified number of breaks which may be larger than 2 but smaller that the maximum allowed number of breaks, m, in univariate time series models. The advocated procedure is considerably less computationally intensive than those widely used in the literature. We provide critical values for the test, examine its small sample properties through Monte Carlo experiments and apply the new test to the Nelson and Plosser macroeconomic series.
