Erhan Bayraktar, Emmet Lawless
We study an infinite-horizon optimal consumption-investment problem for an investor with Epstein-Zin stochastic differential utility in an incomplete market with stochastic investm…
Mean-field games with rough common noise: the compactification approach
Erhan Bayraktar, Xihao He, Xiang Yu +1
We study mean-field game (MFG) problems with rough common noise, in which the representative state dynamics are governed by a controlled rough stochastic differential equation driv…
Goal-based portfolio selection with mental accounting
Erhan Bayraktar, Bingyan Han
We present a continuous-time portfolio selection framework that reflects goal-based investment principles and mental accounting behavior. In this framework, an investor with multip…
