Abstract

This paper examines the temporal relationship of Spanish public debt interest rates over the period from January 1991 to November 1994 between end-of-month observations of Treasury rates of different maturities, ranging from three months to ten years. Applying the cointegration theory, we find empirical support for cointegration of Treasury rates The results confirm the appropriateness of imposing a common stochastic process for interest rates . Lastly, to determine whether the cointegration relationship improves forescast of Treasury rates we compare a VAR model of the interest rates with an error-correction model. The results indicate that the error-correction model improves forescast, but in no case can the efficiency of the Spanish public debt market be denied. Este trabajo examina la relación temporal de los rendimientos del mercado espafiol de deuda pública durante el período que abarca desde enero de 1991 a noviembre de 1994. Aplicando la teoría de la cointegración se obtiene que los rendimientos de la deuda pública española están cointegrados. Esto permite concluir que es apropiado suponer que los tipos de interés siguen procesos estocásticos comunes. Por último, para comprobar si la relación de cointegración mejora la capacidad de predicción de los rendimientos de la deuda pública, se compara un vector autoregresivo (VAR) de los tipos de interés con un modelo de corrección de error (VAR que incorpora la relación de cointegración). Los resultados que se obtienen indican que el modelo de corrección de error mejora la capacidad de predicción, pero en ningún caso puede negarse la eficiencia del mercado español de deuda pública.
