Optimal Risk-Sharing Rules and Equilibria With Non-Additive Expected Utility

This paper explores the consequences of non-additive expected utility on risk-sharing and equilibrium in a general equilibrium set-up. We establish that convexity of an agent's preferences (or strong uncertainty aversion) is equivalent to the convexity of his capacity and concavity of his utility index. We also characterize a weaker form of uncertainty aversion.
