Two by-now folkloric results in the theory of risk sharing are that (i) any feasible allocation is

[PDF][PDF] An axiomatic theory for comonotonicity-based risk sharing

J Dhaene, CY Robert, KC Cheung, M Denuit - 2023 - dial.uclouvain.be
This paper studies the quantile risk-sharing rule introduced in Denuit, Dhaene & Robert

On the optimality of linear residual risk sharing

J Yang, W Wei - Available at SSRN 4954807, 2024 - papers.ssrn.com
In this paper, we explore the optimal risk-sharing problem in the context of peer-to-peer
insurance. Using the criterion of minimizing total variance, we find that the optimal risk …
