Abstract

Recent literature has documented the sensitivity of unit root tests to failure to account for structural change. This paper reconsiders international evidence on the unit root hypothesis while allowing for two structural breaks. We find evidence of two breaks in three-quarters of the data, rejecting the unit root hypothesis in 50% more cases than models that allow for only one structural break. Most of the trend breaks are associated with a change in output levels. As the neo-classical growth model predicts, the magnitude of these level changes is shown here to be related to changes in growth rates during the period following the break.
