Bastiat Debunked Cash for Clunkers in 1850

, , , ,

The left commentariat has been burbling happily about the “success” of the democrat Cash for Clunkers program. It turned out Americans with an active interest in a new car, who happened to have an eligible, low value trade-in on hand, were happy to take some free money to do perhaps slightly more rapidly what they were going to do anyway.

Bruce Yandle points out that the relevance of Cash for Clunkers to one of the best known economic fallacies.

University of California-Berkley economist Christopher Knittel has developed a rigorous assessment of the implied cost of carbon emissions under the clunker program. (“The Implied Cost of Carbon Dioxide Under the Cash for Clunkers Program” [pdf], Center for the Study of Energy Markets, Berkeley, The University of California Energy Institute.) Knittel made plausible assumptions about the average life remaining in vehicles removed from the road, the average fuel economy associated with those vehicles, and the resulting levels of carbon emission that would have survived in the absence of clunkers. Eventually, of course, the clunkers would have died a natural but less dramatic death. Knittel then estimated the carbon reduction gained when the large fleet of clunkers was replaced by a new fuel-efficient fleet. When he ran the numbers, Knittel found the cost per ton of carbon reduced could reach $500 under a set of normal values for critical variables. The cost estimate was $237 per ton under best case conditions. And what does this tell us? The much celebrated Waxman-Markey cap-and-trade carbon-emission control legislation estimates the cost of reducing a ton of carbon to be $28 when done across U.S. industries. Yes, we are getting carbon-emission reductions by way of clunker reduction, but we are paying a pretty penny for it.

Frédéric Bastiat’s brilliant parable of the broken window reminds us that a street hoodlum throwing a brick through a window generates a series of job-generating transactions that might raise GDP by a trivial amount, if it could be measured. Indeed, the idea seems so compelling that people today often speak of the silver lining found in the clouds that create hurricanes. Think of the roofers that become employed. But Bastiat’s key lesson is that a window has been destroyed—and it had value. Before touting the total benefits of clunkers, we must take account of the destroyed vehicles and engines that represented part of the wealth of the nation. As Tony Liller, vice president for Goodwill, put it: “They’re crushing these cars, and they’re perfectly good. These are cars the poor need to buy.”

Finally, over the eons, human communities have contrived all kinds of devices to transmit critical survival skills and compatible behavioral norms. One of these has to do with conservation of wealth. “Waste not, want not,” we are told. “A penny saved, is a penny earned,” we are reminded. Using politics to pay people who destroy valuable vehicles, or to hold crops off the market, or to produce ethanol that may use more energy in production than it adds when burned, teaches a lesson of anti-matter and wealth destruction. When all these considerations are made, Cash for Clunkers sounds like a sorry idea that should not be the model for future policy.

Let’s stop Cash for Refrigerators before the idea spreads further.
