A gr oup of n insurers is assumed to share an exogenous risk whose dynamics is modeled by a Levy process. By solving the extended Hamilton-Jacobi-Bellman equation and utilizing the Lagrangian method\, an explicit form of the eq uilibrium bearing function for each insurer is obtained. We show that the equilibrium bearing functions are mixtures of two common risk sharing stra tegies\, namely the proportional and stop-loss strategies. Thanks to their explicit forms\, analytic properties of the equilibrium bearing functions are thoroughly examined. We later consider three extensions to the origin al model by adding one of the following features: a risk sharing constrain t on the insurers\, a set of financial investment opportunities\, and the insurers' ambiguity towards the exogenous risk. For these extended models\ , the equilibrium bearing functions are once again explicitly solved\, and the impact of the constraint\, investment\, and ambiguity component on th e bearing functions are further examined. We conclude the paper by applyin g our results to the classical risk sharing problem in a pure exchange eco nomy\n DTSTART:20181211T153000Z DTEND:20181211T163000Z LOCATION:Room PK-4610\, CA\, UQAM SUMMARY:Bin Li (University of Waterloo) URL:/mathstat/channels/event/bin-li-university-waterlo o-292378 END:VEVENT END:VCALENDAR
