Touzi's most cited paper,
Applications of Malliavin Calculus to Monte Carlo methods in finance, co-authored by
Eric Fournié,
Jean-Michel Lasry,
Jérôme Lebuchoux and
Pierre-Louis Lions, describes an original probabilistic method to compute
option contract Greeks: delta, gamma, theta, and vega. The method is derived from the formula for
integration-by-parts and uses principles from
Malliavin calculus. Their approach, when computed on standard European option contracts and compared to results yielded from the
Monte Carlo method, happens to be more efficient. This paper had a significant impact in the world of mathematical finance, as previous option contract pricing models were based around the
Black-Scholes model and Monte Carlo simulations. == Awards ==
