Portfolio optimization with a prescribed terminal wealth distribution
Ivan Guo, Nicolas Langrené, Grégoire Loeper +1
This paper studies a portfolio allocation problem, where the goal is to prescribe the wealth distribution at the final time. We study this problem with the tools of optimal mass tr…
Deep neural network for optimal retirement consumption in defined contribution pension system
Wen Chen, Nicolas Langrené
In this paper, we develop a deep neural network approach to solve a lifetime expected mortality-weighted utility-based model for optimal consumption in the decumulation phase of a…
Markovian approximation of the rough Bergomi model for Monte Carlo option pricing
Qinwen Zhu, Grégoire Loeper, Wen Chen +1
The recently developed rough Bergomi (rBergomi) model is a rough fractional stochastic volatility (RFSV) model which can generate more realistic term structure of at-the-money vola…
Explicit approximations of option prices via Malliavin calculus in a general stochastic volatility framework
Kaustav Das, Nicolas Langrené
We establish an explicit approximation formula for European put option prices within a general stochastic volatility model with time-dependent parameters. Our methodology is based…
Fast multivariate empirical cumulative distribution function with connection to kernel density estimation
Nicolas Langrené, Xavier Warin
This paper revisits the problem of computing empirical cumulative distribution functions (ECDF) efficiently on large, multivariate datasets. Computing an ECDF at one evaluation poi…
