El presente artículo ofrece una panorámica de los contrastes específicos de raíz unitaria en presencia de cambio estructural propuestos en la literatura, que pretende servir de guía práctica para el investigador que necesite hacer uso de este tipo de técnicas. Estos contrastes contribuyen a paliar el problema de baja potencia que presentan los tests tradicionales de raíz unitaria cuando la serie cambia de media, y por tanto son los que conviene utilizar en estas situaciones. The aim of this paper is to offer a survey of the tests specifically designed to contrast the existence of a unit root in series affected by structural change in their first moment. It intends to serve as a guide por the applied researcher who needs to determine the order of integration of a series. These tests contribute to solve the problem of low power of the traditional unit root tests in situations where the mean of the series changes at discrete points of time; for this reason, they are appropiate in these cases.
