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...

The Nelson-Siegel and the Svensson models are widely used in practice for fitting the term structure of interest rates. However, due to their highly non-linear nature and the potential danger of multicollinearity, numerical difficulties in estimating these models hamper their implementation. In...

The objective of this paper is to provide a monthly estimation of term structure of spot interest rates and forward interest rates since the beginning of the European Monetary Union. In order to do this, we apply the Fama-Bliss metido, the approximating functions of two of the methods most...

We jointly estimate a New Keynesian Policy Model with a Gaussian affine no-arbitrage specification of the term structure of interest rates, and assess how important inflation, output and monetary policy shocks are as sources of fluctuations in interest rates and the term premium. To mitigate...

This paper seeks to analyse the impact of government debt and other macroeconomic variables on the long term bond yield for South Africa. Recent increases in the government budget deficit and its corresponding borrowing has renewed interest in understanding fiscal dynamics within the economy....

The Nelson-Siegel model is widely used in practice for fitting the term structure of interest rates. Due to the ease in linearizing the model, a grid search or an OLS approach using a fixed shape parameter are popular estimation procedures. The estimated parameters, however, have been reported...

Recent developments in South Africa warrant a complete understanding of the fiscal dynamics within the economy. The government budget deficit has soured to unprecedented levels pushing the debt to GDP ratio above 60%. We seek to reveal in this paper the impact this has on the South African long...

Recent studies documented a sufficient forecasting performance of shadow-rate models in the low yields environment. Moreover, it has been shown that including the macro-variables into the shadow-rate models further improves the results. We build on these findings and evaluate for the U.S....

We show that government spending does play a role in shaping the yield curve which has important consequences for the cost of private and government financing. We combine government spending shock identification strategies from the fiscal macro literature with recent advancements in no-arbitrage...
