journal contribution
posted on 2013-01-01, 00:00 authored by Peter Bank, Dmitry KramkovDmitry KramkovWe provide sufficient conditions for the existence and uniqueness of solutions to a stochastic differential equation which arises in the price impact model developed by Bank and Kramkov (2011) [1] and [2]. These conditions are stated as smoothness and boundedness requirements on utility functions or Malliavin differentiability of payoffs and endowments.
