Event Description

Abstract: Optimal execution and trading algorithms rely on price impact models to quantify trading costs. This talk highlights an extensive class of models and problems for which straightforward closed-form solutions exist. Furthermore, these simple solutions combine with more sophisticated methods to solve non-standard problems, such as nonlinear price impact models.
