Ibrahim Ekren Univ. of Michigan Title: Multidimensional utility maximization with small nonlinear price impact Abstract: In this talk we discuss the multidimensional utility maximisation problem with small nonlinear price impact. Using homogenisation techniques, we obtain a first order expansion of the utility function for small nonlinear price impact. We give a PDE characterisation of the utility loss for small nonlinear price impact and exhibit a family of asymptotically optimal strategies for the problem. This is a joint work in progress with Erhan Bayraktar and Thomas Caye.Date: Monday, January 22, 2018Time: 4:30 pmLocation: Wean Hall 8220Submitted by: BohmanNote: Refreshments at 4:00, WeH 6220. |
