Actuarial Fairness of Crop Insurance Rates with Constant Rate Relativities
发现，若使用恒定乘数因子来确定不同保障水平的保费，则无法实现精算公平；美国两种主流农作物保险产品对低免赔额保单收费过高，这可能是2001年起需要高额补贴才能引导农民转向高免赔额保单的原因。
Increased availability and demand for low‐deductible crop insurance policies have increased focus on crop insurance rating methods. Actuarial fairness cannot be achieved if constant multiplicative factors are used to determine how premiums change as coverage levels increase. A comparison of premium rates generated by the factors used by the two most popular crop insurance products with those generated by a standard yield distribution shows that the popular insurance products overcharge for low‐deductible policies in most counties. This overpricing may explain why large premium subsidies were required to induce farmers to move from low‐deductible to high‐deductible policies beginning in 2001.
