| 520 | $aThis paper studies the optimal design of peer-to-peer (P2P) insurance when heterogeneous participants jointly finance a common fund and purchase external insurance for tail risks. The total cost is decomposed into a fixed premium for outside coverage and a variable, potentially refundable deposit used for internal risk sharing. Using a mean-variance objective, the authors derive closed-form optimal sharing rules and characterize their properties, both with and without individual-rationality constraints. The paper also determines the optimal level of the common deposit and provides numerical illustrations. The results offer a rigorous foundation for designing equitable and efficient P2P insurance mechanisms in heterogeneous groups. | ||
