This paper shows how one can compute option prices from a Bayesian inference viewpoint, using an econometric model for the dynamics of the return and of the volatility of the underlying asset. The proposed evaluation of an option is the predictive expectation of its payoff function. The...

There has been increasing support in the empirical literature that both the probability of default (PD) and the loss given default (LGD) are correlated and driven by macroeconomic variables. Paradoxically, there has been very little effort from the theoretical literature to develop credit risk...

Recently there has been some interest in the credit risk literature in models which involve stopping times related to excursions. The classical Black-Scholes-Merton-Cox approach postulates that default may occur, either at or before maturity, when the firm's value process falls below a critical...

In this contribution, we study structural models of defaultable bond pricing in which default occurs at the first time a relevant process either reaches the default boundary or has spent continuously (or cumulatively) a fixed time period below that threshold. Unlike first-passage time...

In this paper we look at a multifactor Monte Carlo Gaussian Copula based model to price CDO's of ABS's. The probabilities of default are implied from prices of ABS bonds and several notional amortisation schedules are proposed. A detailed sensitivity analysis is done with respect to recovery...

We review multi-factor cross-currency LIBOR market models. We present a new method for the calibration of cross-currency market models to FX markets. We study the case of Power Reverse Dual Currency derivatives. We also present a new version of Least Square monte carlo method which makes...

It is commonly accepted that Commodities futures and forward prices, in principle, agree under some simplifying assumptions. One of the most relevant assumptions is the absence of counterparty risk. Indeed, due to margining, futures have practically no counterparty risk. Forwards, instead, may...
