El proceso de transmisión de la política monetaria a la estructura temporal de los tipos de interés en España
2011
This paper analyses the adjustment grade and speed of interest rates term structure in Spain to changes in official interest rateo For this purpose, we specify and estimate an error-correction model, which considers the anticipation of future policy monetary and this allows obtaining an efficient estimator ofthe long-run relation. Moreover, we consider the possibility of asymmetry in the adjustment process to the equilibrium. The results indicate that interest rates anticipate monetary policy actions. Furthermore, monetary policy is transmitted quickly and completely to the short-term interest rates, while transmission is not complete in long-term interest rates but his speed has increased …
No linealidad y asimetría en el proceso generador del Índice Ibex35
2013
This paper analyzes the behavior of Ibex35 from January 1999 to December 2001, in order to check if it follows a different process from random walk so its return is not a white noise and it can be predictable, against the efficient market hypothesis. For that, a nonlinear generating process of return will be considered and a STAR-APARCH model will be specified. This model allows a nonlinear behavior in the conditional mean and in the conditional variance. The empirical results show that the Ibex35 follows a nonlinear and asymmetric process, both in the conditional mean as in the conditional variance, so the weak-version of efficient market hypothesis is rejected.
