Optimal Risk Sharing under Distorted Probabilities
نویسنده
چکیده
We study optimal risk sharing among n agents endowed with distortion risk measures. Our model includes market frictions that can either represent linear transaction costs or risk premia charged by a clearing house for the agents. Risk sharing under thirdparty constraints is also considered. We obtain an explicit formula for Pareto optimal allocations. In particular, we find that a stop-loss or deductible risk sharing is optimal in the case of two agents and several common distortion functions. This extends recent result of Jouini et al. (2006) to the problem with unbounded risks and market frictions.

Asymptotic Buuer Overrow Probabilities in Multiclass Multiplexers: an Optimal Control Approach 1
We consider a multiclass multiplexer with support for multiple service classes, and dedicated bu ers for each service class. Under speci c scheduling policies for sharing bandwidth among these classes, we seek the asymptotic (as the bu er size goes to in nity) tail of the bu er over ow probability for each dedicated bu er. We assume dependent arrival and service processes as is usually the case...
متن کاملOptimal risk sharing with different reference probabilities
We investigate the problem of optimal risk sharing between agents endowed with cashinvariant choice functions which are law-invariant with respect to different reference probability measures. We motivate a discrete setting both from an operational and a theoretical point of view, and give sufficient conditions for the existence of Pareto optimal allocations in this framework. Our results are il...
متن کاملOptimal Risk Sharing in the Presence of Moral Hazard under Market Risk and Jump Risk
This paper provides a tractable framework to study optimal risk sharing between an investor and a firm with general utility forms in the presence of moral hazard under market risk and jump risk. We show that, for a two-date discrete-time moral hazard model, there exists a continuous-time model that obtains the same optimal result. Moreover, we characterize the optimal risk sharing explicitly, i...
متن کاملComputation of distorted probabilities for diffusion processes via stochastic control methods
We study distorted survival probabilities related to risks in incomplete markets. The risks are modeled as diffusion processes, and the distortions are of general type. We establish a connection between distorted survival probabilities of the original risk process and distortion-free survival probabilities of new pseudo risk diffusions; the latter turns out to be diffusions with killing or spli...
متن کاملRisk Exchange with Distorted Probabilities
An exchange economy is considered, where agents (insurers/banks) trade risks. Decision making takes place under distorted probabilities, which are used to represent either rank-dependence of preferences or ambiguity with respect to real-world probabilities. Pricing formulas and risk allocations, generalising the results of Bühlmann (1980, 1984) are obtained via the construction of aggregate pre...
