Research & Commentary: Insurance Price Controls and California Proposition 103

March 2, 2012

In the mid-1980s, high premium costs and a tidal wave of auto insurance litigation led to vast public outrage against auto insurers. Under California’s referendum process, voters in 1986 narrowly approved Proposition 103, which completely remade the state’s auto insurance system.

Insurers were required to roll back their rates 20 percent below what they were in November 1987. Those rates were then frozen for a year, and future rate changes were subject to enormous new regulations. Prop 103 also required insurers to offer a 20 percent rate cut to any “good driver” and banned the use of residence location and credit scores in determining rates.

Supporters of Prop 103 say the program has been a huge success, claiming the price controls saved California consumers $23 billion in the decade between 1989 and 1998. They argue requiring insurers to justify their rate increases has kept rates down and increased the level of accountability for insurers. Consumer groups in California are now pushing to add health care insurance to the lines covered under Prop 103.

Opponents of Prop 103, which include insurance groups such as the National Association of Mutual Insurance Companies (NAMIC) and pro-market groups such as The Heartland Institute and Cato Institute, counter these claims by showing government price controls on insurance do not lead to better results for consumers and have failed in many of the states where they have been implemented. A NAMIC study found many of the improvements in California’s insurance system after Prop 103 were the result of legal decisions limiting frivolous claims, statewide and private efforts to eliminate fraud, and new safety laws such as stricter DUI and seatbelt laws.

The following articles examine California’s Proposition 103 and the effectiveness of insurance price controls.
