Yield curve models within the popular Nelson and Siegel (hereafter NS) class are shown to arise from a formal low-order Taylor approximation to the generic Gaussian affine term structure model. That theoretical foundation provides an assurance that NS models correspond to a well-accepted...

With nominal interest rates near the zero lower bound (ZLB) in many major economies, it has become untenable to apply Gaussian affine term structure models (GATSMs) while ignoring their inherent theoretical deficiency of non-zero probabilities of negative interest rates. In this article I...

I propose a simple framework that quantifies the stance of monetary policy as a “shadow short rate” when the term structure is near the zero lower bound. I demonstrate my framework with a one-factor model applied to Japanese data, including an intuitive economic interpretation of the...

With nominal interest rates currently at or near their zero lower bound (ZLB) in many major economies, it has become untenable to apply Gaussian affine term structure models (GATSMs) while ignoring their inherent non-zero probabilities of negative interest rates. In this article I modify GATSMs...

This article explains the concept of the yield curve, the pattern of interest rates by their time to maturity, and how that concept helps to provide some perspective on the multitude of different interest rates that exist in modern economies. The dominance of macroeconomic influences on the...

This paper quantifies the impact of monetary policy shocks on asset markets in the United States and gauges the usefulness of a shadow short rate as a measure of conventional and unconventional monetary policy shocks. Monetary policy surprises are found to have had a larger impact on asset...

When nominal interest rates are near their zero lower bound (ZLB), as in many developed economies at the time of writing, it is theoretically untenable to apply the popular class of Gaussian affine term structure models (GATSMs) given their inherent material probabilities of negative interest...

Our approach offers several advantages over LSAPs as a financial mechanism to enhance forward guidance.

When nominal interest rates are near their zero lower bound (ZLB), as in many developed economies at the time of writing, it is theoretically untenable to apply the popular class of Gaussian affine term structure models (GATSMs) given their inherent material probabilities of negative interest...

The Black framework offers a theoretically appealing way to model the term structure and gauge the stance of monetary policy when the zero lower bound of interest rates becomes constraining, but it is time consuming to apply using standard numerical methods. I outline a faster Monte Carlo...
