dc.description.abstractSeveral unit root tests in panel data have recently been proposed. The test developed by Harris and Tzavalis (1999 JoE) performs particularly well when the time dimension is moderate in relation to the cross-section dimension. However, in common with the traditional tests designed for the unidimensional case, it was found to perform poorly when there is a structural break in the time series under the alternative. Here we derive the asymptotic distribution of the test allowing for a shift in the mean, and assess the small sample performance. We apply this new test to show how the hypothesis of (perfect) hysteresis in Spanish unemployment is rejected in favour of the alternative of the natural unemployment rate, when the possibility of a change in the latter is considered.eng
dc.description.abstract- Recentment han estat proposats varis contrastos d¿arrel unitària en l¿entorn de dades de panell. El contrast desenvolupat per Harris i Tzavalis (1999 JoE) es mostra particularment adequat quan la dimensió temporal és moderada en relació a la dimensió del cross-section. No obstant això i a l¿igual que succeeix amb els contrastos tradicionals proposats en l¿entorn univariant, el contrast de Harris i Tzavalis és inadequat quan hi ha un canvi estructural sota la hipòtesi alternativa que afecta les sèries temporals. En aquest article es deriva la distribució asimptòtica del test permetent un canvi en la mitjana i es determina el seu comportament en mostra ¿nita. Aquest nou contrast s¿aplica a un panell format per les tases d¿atur de les províncies espanyoles per mostrar com la hipòtesi de histèresi (perfecta) és rebutjada a favor de l¿alternativa de la tasa natural d¿atur quan es considera la possibilitat d¿un canvi en la mitjanacat
