Dividend ratcheting and capital injection under the Cramér-Lundberg model: Strong solution and optimal strategy

Chonghu Guan, Zuo Quan Xu

We consider an optimal dividend payout problem for an insurance company whose surplus follows the classical Cramér-Lundberg model. The dividend rate is subject to a ratcheting cons…

Optimal Consumption-Investment for General Utility with a Drawdown Constraint over a Finite-Time Horizon

Chonghu Guan, Xinfeng Gu, Wenhao Zhang +1

We study an optimal investment and consumption problem over a finite-time horizon, in which an individual invests in a risk-free asset and a risky asset, and evaluate utility using…

Optimal dividend payout with path-dependent drawdown constraint

Chonghu Guan, Jiacheng Fan, Zuo Quan Xu

This paper studies an optimal dividend problem with a drawdown constraint in a Brownian motion model, requiring the dividend payout rate to remain above a fixed proportion of its h…

Optimal ratcheting of dividend payout under Brownian motion surplus

Chonghu Guan, Zuo Quan Xu

This paper is concerned with a long standing optimal dividend payout problem subject to the so-called ratcheting constraint, that is, the dividend payout rate shall be non-decreasi…

Continuous-time Markowitz's mean-variance model under different borrowing and saving rates

Chonghu Guan, Xiaomin Shi, Zuo Quan Xu

We study Markowitz's mean-variance portfolio selection problem in a continuous-time Black-Scholes market with different borrowing and saving rates. The associated Hamilton-Jacobi-B…

A consumption-investment model with state-dependent lower bound constraint on consumption

Chonghu Guan, Zuo Quan Xu, Fahuai Yi

This paper studies a life-time consumption-investment problem under the Black-Scholes framework, where the consumption rate is subject to a lower bound constraint that linearly dep…

A free boundary problem arising from a multi-state regime-switching stock trading model

Chonghu Guan, Jing Peng, Zuo Quan Xu

In this paper, we study a free boundary problem, which arises from an optimal trading problem of a stock that is driven by a uncertain market status process. The free boundary prob…

Dynamic optimal reinsurance and dividend-payout in finite time horizon

Chonghu Guan, Zuo Quan Xu, Rui Zhou

This paper studies a dynamic optimal reinsurance and dividend-payout problem for an insurance company in a finite time horizon. The goal of the company is to maximize the expected…

Optimal Investment Stopping Problem with Nonsmooth Utility in Finite Horizon

Chonghu Guan, Xun Li, Zuoquan Xu +1

In this paper, we investigate an interesting and important stopping problem mixed with stochastic controls and a \textit{nonsmooth} utility over a finite time horizon. The paper ai…
