Monotone 2D Integration Scheme for Mean-CVaR Optimization via Fourier-Trained Transition Kernels
Duy-Minh Dang, Hao Zhou
We present a strictly monotone, provably convergent two-dimensional (2D) integration method for multi-period mean-conditional value-at-risk (mean-CVaR) reward-risk stochastic contr…

Convergence of Neural Network Policies for Risk--Reward Optimization
Chang Chen, Duy-Minh Dang
We develop a neural-network framework for multi-period risk--reward stochastic control problems with constrained two-step feedback policies that may be discontinuous in the state.…

Money-Back Tontines for Retirement Decumulation: Neural-Network Optimization under Systematic Longevity Risk
German Nova Orozco, Duy-Minh Dang, Peter A. Forsyth
Money-back guarantees (MBGs) are features of pooled retirement income products that address bequest concerns by ensuring the initial premium is returned through lifetime payments o…
