S-shaped Utility Maximization with VaR Constraint and Partial Information

Dongmei Zhu, Ashley Davey, Harry Zheng

We study S-shaped utility maximisation with VaR constraint and unobservable drift coefficient. Using the Bayesian filter, the concavification principle, and the change of measure,…

Convergence of Proximal Policy Gradient Method for Problems with Control Dependent Diffusion Coefficients

Ashley Davey, Harry Zheng

We prove convergence of the proximal policy gradient method for a class of constrained stochastic control problems with control in both the drift and diffusion of the state process…

Deep Learning Methods for S Shaped Utility Maximisation with a Random Reference Point

Ashley Davey, Harry Zheng

We consider the portfolio optimisation problem where the terminal function is an S-shaped utility applied at the difference between the wealth and a random benchmark process. We de…

Duality for optimal consumption with randomly terminating income

Ashley Davey, Michael Monoyios, Harry Zheng

We establish a rigorous duality theory, under No Unbounded Profit with Bounded Risk, for an infinite horizon problem of optimal consumption in the presence of an income stream that…

Deep Learning for Constrained Utility Maximisation

Ashley Davey, Harry Zheng

This paper proposes two algorithms for solving stochastic control problems with deep learning, with a focus on the utility maximisation problem. The first algorithm solves Markovia…
