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...

The existing literature promotes a number of alternative methods to test for the presence of contagion during financial market crises. This paper reviews those methods, and shows how they are related in a unified framework. A number of extensions are also suggested which allow for multivarite...

Asset market interconnectedness can give rise to significant contagion risks during periods of financial crises that extend beyond the risks associated with changes in volatilities and correlation. These channels include the transmission of shocks operating through changes in the higher order...

Cities have been investing heavily in recent years to augment their water supply, focusing on either stormwater harvesting or desalination. A more optimal strategy is to consider all sources of water jointly, thereby allowing for hedging of supply risks. A portfolio model of urban water supply...
