We introduce a general continuous-time model for an illiquid financial market where the trades of a single large investor can move market prices. The model is specified in terms of parameter dependent semimartingales, and its mathematical analysis relies on the non-linear integration theory of...

We introduce the notion of a convex measure of risk, an extension of the concept of a coherent risk measure defined in … Artzner et aL (1999), and we prove a corresponding extension of the representation theorem in terms of probability measures on … the underlying space of scenarios.
