Since climate change legislation entered the public agenda, conservatives have been arguing that doing anything about global warming will cost too much. The most persistent commentator along these lines has been Robert Samuelson who wrote recently:
To comply with the House bill, CO2 emissions would have to be about 3.5 billion tons. The claims of the Environmental Defense Fund and other environmentalists that this reduction can occur cheaply rely on economic simulations by “general equilibrium” models. An Environmental Protection Agency study put the cost as low as $98 per household a year, because high energy prices are partly offset by government rebates. With 2.5 people in the average household, that’s roughly 11 cents a day per person.
The trouble is that these models embody wildly unrealistic assumptions: There are no business cycles; the economy is always at “full employment”; strong growth is assumed, based on past growth rates; the economy automatically accommodates major changes — if fossil fuel prices rise (as they would under anti-global-warming laws), consumers quickly use less and new supplies of “clean energy” magically materialize.
But this report from the Congressional Budget Office estimates the cost to households of the Waxman-Markey bill now before Congress would be about 48 cents per day. Will we hear a retraction coming from Samuelson?
As Paul Krugman says:
The point is that we need to be clear about who are the realists and who are the fantasists here. The realists are actually the climate activists, who understand that if you give people in a market economy the right incentives they will make big changes in their energy use and environmental impact. The fantasists are the burn-baby-burn crowd who hate the idea of using government for good, and therefore insist that doing the right thing is economically impossible.
This is right. The aim of Republican statements about policy is not to solve problems but to perpetuate the irrational anti-government animus that kept them in power for many years.
