(Department of Economics Working Paper Series, Number 1/05). Hamilton, New Zealand: University of Waikato.https://hdl.handle.net/10289/1648This article derives a generic, intertemporally-consistent, and arbitrage-free version of the popular class of yield curve models originally introduced by Nelson and Siegel (1987). The derived model has a theoretical foundation (conferred via the Heath, Jarrow and Morton (1992) framework) that allows it to be used in applications that involve an implicit or explicit time-series context. As an example of the potentialapplication of the model, the intertemporal consistency is exploited to derive a theoretical time-series process that may be used to forecast the yield curve. The empirical application of the forecasting framework to United States data results in out-of-sample forecasts that outperform the random walk over a sample period of almost 50 years, for forecast horizons ranging from six months to three years.application/pdfenyield curveterm structure of interest ratesNelson and Siegel modelHeath-Jarrow-Morton frameworkWorking Paper
