Abstract

En este trabajo se estudian los procesos de raíz unitaria estocástica (STUR) como una generalización de los procesos de raíz unitaria fija. Así, se repasan tanto sus principales características estadísticas, como los métodos de detección y contraste desarrollados para este tipo de procesos. Finalmente, se estudia la relevancia empírica de estos procesos en la modelización de los índices bursátiles de los principales mercados mundiales, realizando una comparación tanto de las varianzas condicionadas como de las predicciones de los rendimientos, obtenidas con procesos STUR, frente a otros procesos de la literatura financiera.
