A general parametric framework based on the generalized Student t-distribution is developed for pricing S&P500 options. Higher order moments in stock returns as well as time-varying volatility are priced. An important computational advantage of the proposed framework over Monte Carlo-based...

A method for estimating the parameters of stochastic differential equations (SDEs) by simulated maximum likelihood is presented. This method is feasible whenever the underlying SDE is a Markov process. Estimates are compared to those generated by indirect inference, discrete and exact maximum...

The paper describes the methods used by the French Banking Supervision Authority (ACP) to run stress tests for the corporate credit portfolio, through credit migration matrices (or transition matrices). This approach is currently used for “top-down” stress tests exercises. Developed for...
