Pay-As-You-Drive Insurance Comes to Brookingsby Dean Baker
Many of the ways to reduce greenhouse gas emissions will require major changes in behavior and/or impose serious costs. However, there is one mechanism that could lead to substantial reductions in emission with no cost: pay-as-you-drive auto insurance.
The basic point is simple. With current policies, most people will pay the same amount for their insurance whether they drive 500 miles or 50,000 miles. However, their risk of being in an accident is clearly greater the more miles they drive. If we can have insurance prices reflect the increased risk, it would mean both better insurance pricing and giving people a substantial disincentive to drive.
The impact would be large. The average cost of insurance per mile driven is close to 8 cents. This means that if insurance were paid on a per mile basis, for a car that gets 20 miles to a gallon, pay-as-you-drive insurance would provide the same disincentive to drive as a $1.60 a gallon gas tax. This can easily lead to reductions in gas consumption and greenhouse gas emissions from the auto sector of 10 percent or more.
The great part is that it doesn’t even raise driving costs on average, it just makes a fixed cost - the annual insurance premium - into a per mile cost. Since people will now presumably drive less and therefore have fewer accidents, they should actually end up paying less on average for insurance.
I first wrote about this a decade ago with my then colleague at the Economic Policy Institute, Jim Barrett. Others had written about pay as you drive even earlier, such as Patrick Butler with the National Organization for Women, Daniel Khazzoom at San Jose State University, Todd Littman at the Victoria Transport Institute and Aaron Edlin, now at Berkeley. The reason for mentioning pay-as-you-drive insurance now is being discussed in the mainstream of the economics profession. Two researchers affiliated with the Brookings Institution recently wrote a piece touting the
merits of pay-as-you-drive insurance. .......(more)
