A multi-state Vasicek model for correlated default rate and loss severity
Correlation between default and recovery has an important bearing on credit risk capital. Here, Rahul Sen shows that the effect can be modelled efficiently by allowing multiple loss states in the Vasicek framework. Heavy-tailed distributions result for…

Inflation is normal
Chris Kenyon introduces normal-based smile models for year-on-year inflation motivated by the observation that market lognormal caplet volatilities of less than 1% imply normality for maturities of up to 30 years. He is also motivated by the range of…
Convexity adjustments in inflation-linked derivatives
Dorje Brody, John Crosby and Hongyun Li value several types of inflation-linked derivatives using a multi-factor version of the Hughston (1998) and Jarrow & Yildirim (2003) model. Expressions for the prices of zero-coupon inflation swaps with delayed…
Gamma loss and prepayment
Peter Jackel presents a model for the dynamics of fractional notional losses and prepayments on asset-backed securities for the valuation and risk management of derivatives, including waterfall structures and other structured debt obligations on bespoke…
Let's jump together: pricing credit derivatives
Joao Garcia, Serge Goossens and Wim Schoutens introduce a dynamic multivariate jump-driven model for credit spreads. The model parameters come from a calibration on swaptions and a correlation-matching procedure. The authors apply the model to credit…
Combining the SABR and LMM models
Pierre Henry-Labordere analyses a stochastic volatility Libor market model that combines the SABR and Brace-Gatarek-Musiela (BGM) models in a natural way. Using an innovative geometrical method, he explains how to obtain analytical formulas for swaption…
