Standard Gaussian term structure models have often been criticized for not ruling out negative nominal interest rates, but this flaw has been especially conspicuous with interest rates near zero in many countries. We provide a tractable means to estimate an alternative Gaussian shadow-rate...

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...

This paper quantifies the role of alternative shocks in accounting for the recent declines in Japanese saving rates and interest rates and provides some projections about their future course. We consider three distinct sources of variation in saving rates and real interest rates: changes in...

At the center of the financial market crisis of 2007-2008 was a highly unusual jump in spreads between the overnight inter-bank lending rate and term London inter-bank offer rates (Libor). Because many private loans are linked to Libor rates, the sharp increase in these spreads raised the cost...

Linearized New Keynesian models and empirical no-arbitrage macro-finance models offer little insight regarding the implications of changes in bond term premiums for economic activity. We investigate these implications using both a structural model and a reduced-form framework. We show that there...

The basic inability of standard theoretical models to generate a sufficiently large and variable nominal bond risk premium has been termed the "bond premium puzzle." We show that the term premium on long-term bonds in the canonical dynamic stochastic general equilibrium (DSGE) model used in...

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 article assesses the importance of the zero lower bound on nominal interest rates for the conduct of monetary policy. The article employs a small, forward-looking model developed by Fuhrer and Moore. The model is simulated under several policy rules that involve either high or low inflation...

This paper describes an empirical framework for analyzing the monetary transmission mechanism through which changes in monetary policy affect real GDP and inflation. The framework reflects the work of a large number of empirical researchers who have built econometric models of the impacts of...
