This paper proposes a possible way of assessing the effect on interest rate dynamics of changes in the decision-making approach, in the communication strategy and in the operational framework of a central bank. Through a GARCH specification we show that the US and the euro area displayed a...

Aim of this article is to judge the empirical performance of 'ARCH models as diffusion approximations' of models of the short-term rate with stochastic volatility. Our estimation strategy is based both on moment conditions needed to guarantee the convergence of the discrete time models and on...

We study the dynamics of risk premiums on the German bond market, employing no-arbitrage term-structure models with both observable and unobservable state variables, recently popularized by Ang and Piazzesi (2003). We conduct a specification analisys based on a new canonical representation for...

The role of movements in real rates in explaining the relationship between long and short-term interest rates is explored using a model of optimal government debt management.
