Jeffry Dorfman, an agricultural economist at the University of Georgia, weighed in on Obama's proposed environmental regulations at Real Clear Markets. After discussing the fact that the environmental effects are probably smaller and more nuanced than most people expect, the got to the economics of the issue:
First, rising energy prices. A fascinating part of the special-interest coalition that makes up the Democratic Party is how many of its groups have aims which are at odds with another coalition partner. Environmental groups advocate a set of policies that uniformly hurt poor people. Environmental protection is essentially a luxury good. If you have enough money to provide food, clothing, and shelter for your family, then you start to care about the environment.
Krugman and I can both afford to pay a little more on our electricity bill and when we fill up our gas tanks, but those higher energy costs are regressive. Poor people spend a higher percentage of their income on energy bills, so raising those costs in order to improve the environment means that the poor will feel more pain than those with higher incomes. If we were talking about tax policy, no liberal would forget to mention the poor and how the rich should carry more of the burden. Yet, somehow, on environmental policy most liberals favor policies which hurt the very people they normally want to help.
Then he gets into the broken-window fallacy - that somehow by forcing companies to invest in new equipment, everyone can be made better off.
Now if we build a brand new power plant while continuing to operate all the ones we have, that can lead to economic growth because we are increasing the productive capacity of the economy. But shutting down a plant that is fine in every way except for producing emissions that worry some people is the same as when a natural disaster destroys property. Something that had value no longer exists. The idea that replacing the previous item leads to economic growth is one of the most basic fallacies in all of economics, known as the broken window fallacy.
The Eli Lehrer in the Weekly Standard also had an interesting response to Obama's proposed environmental regulations. Here is one snippet:
Indeed, if free-market conservatives really want evidence of climate change, they ought to look towards the insurance markets that would bear much of the cost of catastrophic climate change. All three of the major insurance modeling firms and every global insurance company incorporate human-caused climate change into their projections of current and future weather patterns. The big business that has the most to lose from climate change, and that would reap the biggest rewards if it were somehow solved tomorrow, has universally decided that climate change is a real problem. An insurance company that ignored climate change predictions could, in the short term, make a lot of money by underpricing its competition on a wide range of products. Not a single firm has done this.
and yet, Lehrer rightly says:
The scientific consensus that exists about the causes and effects of climate change can’t point to an optimal policy solution any more than improvements in heart surgery techniques can provide guidance on health care reform.
