How Community Rating Hurts Those it is Designed to Help
This illustration comes from Avik Roy:
In the first bar, there is a classically underwritten distribution of insurance costs: the 18-year-old pays $800 in premiums, and the 64-year-old pays $4,800: six times as much. Then, in the second bar, 3-to-1 community rating is imposed, which redistributes the cost of premiums. Now, 18-year-olds must pay $1,400 for insurance—a 75 percent increase—so that 64-year-olds can pay 13 percent less… after adverse selection, the oldest policyholder ends up paying more than he would have under free-market underwriting: $4,900 instead of $4,800. A government policy aimed at forcing young people to subsidize premiums for the elderly ends up driving up costs for everybody.
