Reinforcement learning for irreversible reinsurance problems: the randomized singular control approach
Zongxia Liang, Xiaodong Luo, Xiang Yu
This paper studies the continuous-time reinforcement learning for stochastic singular control with the application to an infinite-horizon irreversible reinsurance problem. The sing…
Equilibrium Portfolio Selection under Utility-Variance Analysis of Log Returns in Incomplete Markets
Yue Cao, Zongxia Liang, Sheng Wang +1
This paper investigates a time-inconsistent portfolio selection problem in the incomplete mar ket model, integrating expected utility maximization with risk control. The objective…
Mean-Field Game of Relative Performance Portfolio for Two Populations with Poisson Common Noise
Yuchen Li, Zongxia Liang, Xiang Yu
This paper studies the mean field game (MFG) and N-player game on relative performance portfolio management with two heterogeneous populations. In addition to the Brownian idiosync…
Portfolio Selection with Costly Information Acquisition
Zongxia Liang, Shu Wang, Jianming Xia
We investigate joint optimization on information acquisition and portfolio selection within a Bayesian adaptive framework. The investor dynamically controls the precision of a priv…
Mean Field Game with Reflected Jump Diffusion Dynamics: A Linear Programming Approach
Zongxia Liang, Xiang Yu, Keyu Zhang
This paper develops a linear programming approach for mean field games with reflected jump-diffusion dynamics. We first prove the equivalence between the mean field equilibria in t…
Robust Utility Maximization with Intractable Claims under Distributional Ambiguity: A Random Distributionally Robust Optimization Approach
Guohui Guan, Zongxia Liang, Xingjian Ma
This paper studies a robust utility maximization problem for intractable claims under distributional ambiguity, where the distribution of the claim cannot be inferred from market i…
