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.
