Representation of forward performance criteria with random endowment via FBSDE and application to forward optimized certainty equivalent

no code implementations29 Dec 2023 Gechun Liang, Yifan Sun, Thaleia Zariphopoulou

We, also, consider representative examples for both forward performance criteria with random endowment and forward OCE, and for the case of exponential criteria, we investigate the connection between forward OCE and forward entropic risk measures.

Predictable Relative Forward Performance Processes: Multi-Agent and Mean Field Games for Portfolio Management

no code implementations8 Nov 2023 Gechun Liang, Moris S. Strub, Yuwei Wang

We consider a new framework of predictable relative forward performance processes (PRFPP) to study portfolio management within a competitive environment.

Callable convertible bonds under liquidity constraints and hybrid priorities

no code implementations3 Nov 2021 David Hobson, Gechun Liang, Edward Wang

This paper investigates the callable convertible bond problem in the presence of a liquidity constraint modelled by Poisson signals.

Predictable Forward Performance Processes: Infrequent Evaluation and Applications to Human-Machine Interactions

no code implementations17 Oct 2021 Gechun Liang, Moris S. Strub, Yuwei Wang

We study discrete-time predictable forward processes when trading times do not coincide with performance evaluation times in a binomial tree model for the financial market.

A game theoretical approach to homothetic robust forward investment performance processes in stochastic factor models

no code implementations6 May 2020 Juan Li, Wenqiang Li, Gechun Liang

This paper studies an optimal forward investment problem in an incomplete market with model uncertainty, in which the underlying stocks depend on the correlated stochastic factors.

no code implementations26 Jan 2020 Gechun Liang, Xingchun Wang

This paper proposes a hybrid credit risk model, in closed form, to price vulnerable options with stochastic volatility.

no code implementations3 Jul 2018 Wing Fung Chong, Gechun Liang

This paper studies robust forward investment and consumption preferences within a zero-volatility context.
