In this discussion paper we introduce time-varying parameters in the dynamic Nelson–Siegel yield curve model for the simultaneous analysis and forecasting of interest rates of different maturities. The Nelson–Siegel model has been recently reformulated as a dynamic factor model with vector...

We propose a new approach to the modelling of the term structure of interest rates. We consider the general dynamic factor model and show how to impose smoothness restrictions on the factor loadings. We further present a statistical procedure based on Wald tests that can be used to find a...

This paper studies empirical issues of one-factor yield curve models. We focus on the models by Ho & Lee (1986), Hull & White (1990) and Moraleda & Vorst (1996). To be consistent in the comparison of the models, we derive them all within the Ritkchen and Sankarasubramanian (1995) framework,...

This paper examines whether the ECB's Quantitative Easing (QE) policy is causing government bond prices to deviate from their fundamental value. We use a recent advance in the methodology to measure exuberant price behavior in financial time series introduced by Phillips et al. (2015). We extend...
