In contrast to multi-factor models, random field models offer a parsimonious description of term structure dynamics, while eliminating the self-inconsistent practice of recalibration....

We identify a class of term structure models possessing a generalized affine-structure that significantly extends the class studied by Duffie, Pan, and Singleton (2000) and Chacko and Das (2002). This class of models, which includes bothinfinite-state-variable (i.e., HJM-type) and...

Several recent papers document significant relative mis-pricings between caps and swaptions using traditional multi-factor models of the term structure. Below we argue that these mis-pricings are due to the severe restrictions that traditional models place on the joint evolution of the i) term...

Most term structure models with stochastic volatility are restrictive in that they assume the risk in derivative securities can be perfectly hedged by a portfolio consisting solely of bonds. Below, we demonstrate that this prediction fails in practice. In particular, we find that the changes in...

What properties must a term structure model possess in order to have closed-form bond price solutions? Are there undiscovered models which offer simple bond price formula? Why do models that have closed-form bond price solutions also tend to have closed-form bond-option solutions? This paper...

Empirical tests of reduced form models of default attribute a large fraction of observed credit spreads to compensation for jump-to-default risk. However, these models preclude a "contagion-risk'' channel, where the aggregate corporate bond index reacts adversely to a credit event. In this...

Many leading asset pricing models predict that the term structures of expected returns and volatilities on dividend strips are strongly upward sloping. Yet the empirical evidence suggests otherwise. This discrepancy can be reconciled if these models replace their exogenously specified dividend...

We investigate a structural model of market and firm-level dynamics in order to jointly price long-dated S&P 500 options and tranche spreads on the five-year CDX index. We demonstrate the importance of calibrating the model to match the entire term structure of CDX index spreads because it...

The 1987 stock market crash occurred with minimal impact on observable economic variables (e.g., consumption), yet dramatically and permanently changed the shape of the implied volatility curve for equity index options. Here, we propose a general equilibrium model that captures many salient...
