We generalize the arbitrage-free Nelson Siegel (AFNS) model to allow λt to vary over time. We find that the time-varying λt, which determines the relative factor loadings, typically reaches its local peak before starting to decline right before a recession. Through conducting extensive...

We employ conformal symmetries to provide a generic tractable framework for interest rate modelling. The approach combines calibration flexibility of market models with tractability and computational efficiency of shot rate models. The methodology enables robust calibration to the whole variety...

This paper describes the search for a yield curve model that embodies current research but will be used for product pricing, investment advice and asset liability management over long horizons. A variety of available 3-factor affine models are implemented and tested, often with surprising...

We define a disastrous default as the default of a systemic entity. Such an event is expected to have a negative effect on the economy and to be contagious. Bringing macroeconomic structure to a noarbitrage asset-pricing framework, we exploit prices of disaster-exposed assets (credit and equity...

Economic assets can be classified into two broad categories: those earning an inherent return and those earning a fiat money return. This article shows that both are valued according to the same general principle based on GDP (a constant equal to expected long term real per capita GDP growth)...

The theoretical literature on term structure models emphasises the importance of the expected absorption of duration risk during the residual life of term bonds in order to understand the yield curve effect of central banks’ government bond purchases. Motivated by this, we develop a...

Yield curves are used to imply the forward rates and discount factors from market tradable instruments and are required to discount future cash flows and evaluate the price of all financial contracts. Not all instruments can be included in the yield curve calibration or fitting process, hence we...

This paper is a study of the history of the transplant of mathematical tools using negative feedback for macroeconomic stabilization policy from 1948 to 1975 and the subsequent break of the use of control for stabilization policy which occurred from 1975 to 1993. New-classical macro-economists...
