Abstract

This study assesses the impact of 9/11 on the Market’s risk aversion using S&P500 options. Risk Neutral densities are extracted through Lognormal Polynomials, Generalized Beta Distribution of the second kind and Mixture of two Lognormal Distributions methods, being the latter, the one which performs the best. There is an evident change in terms of density shape after 9/11. Risk aversion coefficients were estimated assuming an Expected Utility model and a Rank Dependent Expected Utility model. Under Expected Utility model, risk aversion coefficient yield an apparent irrational negative number, while RDEU exhibits positive values, with an increase in risk aversion after 9/11.
