Research On The Relationship Between The Risk Characteristics And Deductibles Of The Insured Objects

The deductible is applied to the insurance business and recently the insurance companiesregard deductibles as important. But there are still some disputes about the deductible setting.If the deductible is not reasonable, it cannot be given the full scope. So the deductible scienceis crucial.According to the insurable risk conditions, a small loss risks are uninsurable whichoccupy a large number of claim resources. And the function of the deductible is to removemany small risk loss for the insured objects, to achieve the risk insurable object and to reduceinsurance costs. But the utility function, the bankruptcy probability, the qualitativedescriptions and the game theory are not reasonable to calculate the deductible, are subjective,and are not based on objective basis. So in this paper，put forward the risk insurable conceptand study the relationship between deductibles and risk insurable, combine with the riskcharacteristics of insured objects, consider the change between deductibles and the premiumrate,then determine a mathematical model for setting deductibles. Above all, determine theway of deductibles and optimal deductible amount.Finally, in order to provide the mode, so adopt an example to verify the method todetermine the deductible. This method can not used for reference of setting deductible.
