Some generalizations of the Nelson and Siegel (1987) models are widely applied in central banks and financial institutions. This paper introduces a discrete-time version of the generalized Nelson-Siegel term structure models proposed by Svesson (1995) and Björk and Christensen (1999). As in...

Using a stochastic discount factor approach, we derive the exact solution for arbitrage-free bond yields for the case that the short-term interest rate follows a threshold process with the intercept switching endogenously. The yield functions, mapping the one-month rate into n-period yields,...

The Svensson generalization of the popular Nelson-Siegel term structure model is widely used by practitioners and central banks. Unfortunately, like the original Nelson-Siegel specification, this generalization, in its dynamic form, does not enforce arbitrage-free consistency over time. Indeed,...

This paper uses a risk-averse formulation of the uncovered interest rate parity to determine exchange rates through interest rate differentials, and ultimately extract currency risk premia. The method proposed consists of developing an affine Arbitrage-Free class of dynamic Nelson-Siegel term...

This study outlines an affine term structure model (ATSM) of TIPS that decomposes yields into real expected rates, real term premiums, and liquidity premiums. The estimation incorporates an observable liquidity factor that more comprehensively captures limits to arbitrage implied by yield curve...

We derive the class of arbitrage-free affine dynamic term structure models that approximate the widely-used Nelson-Siegel yield-curve specification. Our theoretical analysis relates this new class of models to the canonical representation of the three-factor arbitrage-free affine model. Our...
