We consider the valuation and risk management of derivatives on defaultable assets such as bonds taking into account funding (FVA), cash collateral, underlying default, counterparty default (CVA) and default correlation using joint default poisson process. The framework can be considered as an...

Multi-factor interest-rate models are widely used. Contingent claims with early-exercise features are often valued by resorting to trees, finite-difference schemes and Monte Carlo simulations. When jumps are present, however, these methods are less effective. In this work we develop an algorithm...

The illiquidity of long-maturity options has made it difficult to study the term structures of option spanning portfolios. This paper proposes a new estimation and inference framework for these option-implied term structures that addresses long-maturity illiquidity. By building a sieve estimator...

the term structure of SPX volatility smiles very well, from the shortest expiration dates all the way up to one year, on … three distinct market conditions. The ATM volatility, adjusted by diffusion time sqrt(T), is hypothesized to be equal to the … standard deviation of the underlying λ distribution. The volatility parameter σ(T) is thus deterministic and the shift …

In practice, rather than to presume a hypothetical condition that needs be validated theoretically, it is sufficient to accept a real condition that exists and can be directly validated for practical purposes. This paper presents a practical approach to formulating the theoretical price of a...

This paper proposes an integrated pricing framework for convertible bonds, which comprises firm value evolving as an exponential jump diffusion, correlated stochastic interest rates movements and an efficient numerical pricing scheme. By construction, the proposed stochastic model fits in the...

This note is an answer the consultation published by ISDA regarding the amendment of documentation to implement fallbacks for certain key IBORs. The answers refer to many technical issues. More details about those issues can be found in the technical note 'A quant perspective on IBOR fallback...
