DFL gubernatorial candidate Mike Hatch wants to set arbitrary requirements for renewable energy use. Incumbent Gov. Tim Pawlenty, a Republican, agrees completely and notes he had the idea first. While these candidates are united in support of command-and-control environmental policy, economists are united in thinking that arbitrary mandates — such as percentages of ethanol in gasoline or electricity from wind — are the stupidest way to reduce energy use and pollution.
Regular readers of this column know what is coming next: For more than a century, economists have agreed that the most effective way to reduce harmful pollution — or something else like energy use that has external costs — is to tax it. Such taxes achieve a greater reduction of these problems at the lowest cost to society.
Despite remarkable agreement among economists, politicians obviously are not convinced, even though conservative think tanks and liberal environmental groups crank out policy studies supporting the economists. Aren't economists just Johnny-One-Notes on this issue? Why don't we simply give up and shut up?
The answer is that the issue is too important to abandon. With concern about climate change and turmoil in the Mideast, it is more important than ever to reduce the external costs of excessive oil use and pollution.
