Insuring Non-Veriable Losses And The Role Of Intermediaries
The authors analyze optimal risk sharing arrangements when losses are observable by policyholders and insurers but not verifiable. The optimal contract to insure individual losses can be implemented through a standard insurance contract with a deductible where the policyholder bears all losses lower than the deductible and an upper limit that restricts the maximum payment to the policyholder. For a group of policyholders it is optimal to choose contracts with individual deductibles and a joint upper limit. Insurance brokers can play an important role in implementing these contracts.
