Abstract:
|
The existing literature investigating the persistence properties of per capita output has primarily focused on the application of unit root tests allowing for structural breaks under the trend stationary alternative. These tests, however, provide little information regarding the existence and number of trend breaks. Moreover, these tests suffer from serious power and size distortions due to the asymmetric treatment of breaks under the null and alternative hypotheses. This paper estimates the number of breaks in trend employing procedures that are robust to the unit root/stationarity properties of the data. Our analysis thereby permits a robust classification of countries according to the "growth shift", "level shift" and "linear trend" hypotheses. Unit root tests conditional on the presence/absence of breaks do not provide evidence against the unit root hypothesis.
