Abstract

Resumen:Este artículo analiza diversas metodologías para la modelación de la volatilidad de la tasa de interés a corto plazo. Específicamente se analizarán los resultados que se obtienen a través de la especificación CKLS, Heterocedasticidad Condicionada y Mixta. Los hechos estilizados ensenan que la mejor especificación para describir el proceso generador de la tasa de interés interbancaria en la economía colombiana para el período 2001-2006 es el modelo EGARCH. Se encuentra que las innovaciones positivas en la tasa de interés ocasionan una volatilidad 22,3% mayor que innovaciones negativas de la misma magnitud. Además, el proceso converge a una media no condicionada de 7,11% con una corrección diaria del 1,2%. Se encuentra que el modelo ofrece pronósticos relativamente sensatos a un plazo de tres meses.Abstract: In this paper we analyze different methodologies that are used to handle the short term interest rate volatility. Specifically, we shall analyze the outcomes that are obtained through three specifications: CKLS, Conditional Heteroscedastic and BHK. The evidence shows that the better specification is reached through the EGARCH model. It is found that positive shocks in the short term interest rate cause a volatility 22,3% higher than negative shock of the same size. Also, the process converges to an unconditioned mean of 7,11% with a correction factor of 1,2% daily. It is found that the model offers good forecast in a period of three months.
