Paul Krugman is a very sharp guy, conversant in many different fields. Yet his analysis of the economics of climate change is as wrongheaded as his analysis of depressions. Relying just on the IPCC “consensus” estimates as well as a leading model such as Nordhaus’s, it is impossible to justify the draconian emission cuts in Waxman-Markey. FULL ARTICLE

Incidentally, you could say the same thing about respecting the property rights of holdouts when the public needs their land for an important project.
CBA, all the way.
(Sorry, delete the previous post.)
Mr. Krugman is an economist; however, when he discusses economics he generally speaks foolishness that is motivated by politics, power, and professional remuneration and advancement. Did we really believe that his analysis of climate change issues, both those aspects that rely on the natural sciences and those that rely on economics, would be any different? The court economist is also the court climatologist.
With climatology we are witnessing the perversion of another area of scientific inquiry to political control. Similar to mainstream practitioners in economics, other social sciences, and history, mainstream climatologists are typically paid propagandists for politicians and certain special interest groups. I hate to sound pessimistic, but statism and totalitarianism continue their advancement.
“It’s true, such stringent limits would reduce the amount of climate damage future generations would suffer…”
It would? You’re assuming that CO2 is harmful.
One of the biggest fallacies in economics is to project current trends indefinitely into the future. If you want to see how wrong Krugman’s analysis can be, go back 40 years in Zimbabwe, (I think in was called Rhodesia in those days), and project forward 40 years.
Keynes is famous for the quote “In the long run we are all dead.” Under the current “Keynes on steroids approach”, the long run may be the end of 2010. Waxman-Markey is a tax.Where is the economic production going to come from to pay this tax?
The inefficiency of alternative energy sources is reflected in the price. To generate 1MWH of electricity costs about $30 for coal, $90 for wind, and $120 for solar. To claim that this effect is minimal is contrary to common sense.
Be a good steward of the environment. But question the politics of global warming:

I’ve always been _underwhelmed_ by Krugman’s breadth of historical, political, and scientific knowledge.
This guy is massively overrated by the members of the economics guild.
The guy can write — always over estimated as a metric of intelligence, understanding and knowledge.
And he articulates the findings of “geographical” and trade economics very well.
I get it.
I’m still massively underwhelmed by Krugman, based on reading several of his popular books, his blog and his NY Times column.
So why don’t they think the economy can cope with limits on greenhouse gas emissions? Under cap-and-trade, emission rights would just be another scarce resource, no different in economic terms from the supply of arable land.
Krugman, an economist, doesn’t understand the difference between political barriers and the natural limits of a truly scarce resource? Sure, the economy could adapt to cap-and-trade, easily, but that doesn’t make it economically necessary.
Dennis mentions climatology. However, there is no science of climatology. There are physics, chemistry, biology, geology, astronomy, math, etc. But the relevant parts of these have not yet been induced into a new science of climatology. A new science of climatology would be an induction of a vast range of data, over eons, into a few very wide principles which would explain and predict climate. Eg, Newton’s Three Laws of Motion. Little bits and pieces of out-of-context data are not science.
@Michael_A._Clem: Like Bob_Murphy, you’re the one with a hole in your understanding of scarcity. Assuming the claims about greenhouse gasses are true (the premise of both Krugman’s and Murphy’s writings that you’re addressing), then the emissions of CO2 by some people come at the cost of consumption by others (in the form of property rendered unusable).
Any time one person’s consumption means another person cannot consume as much, there is scarcity. Yes, the two goods are different in this case (fuel vs. land), but the concept remains.
Don’t feel bad; Bob_Murphy made the same mistake. But yes, there is natural scarcity here.
It’s most interesting to me that these climate screamers never consider that future entrepreneurs might figure out something that solves the (perceived in this case) problem with a little smarts. Can you imagine how wealthy one could become if they solve this “problem”.
For example, there’s a few researchers that are working on some genetic modifications to some plants that would have these plants scrub the atmosphere of excess co2. Maybe all that would be needed would be to do a Johnny Appleseed with some wild grasses.
And they always freeze technology in its tracks. If the last 50-100 years are any indication, the technology that will be available in 50 years from now most likely will make any climate “problem” a trivial one, if it was ever a problem to begin with – and I see this is more of a battle for power than anything else.
And this last point is precisely where I place anything written by Krugman. I’ve not seen any photo of him lately where he doesn’t have that s… eating grin on his face – I would too if I’d become rich by writing trash in the n.y. times.
Let’s assume for the moment that reducing carbon emissions is an urgent priority. Then a proper economic analysis would do a cost benefit analysis to determine the most cost effective way to achieve the desired result. In this case, we would look at a number of alternatives (excuse the grammatical mistake!).
Using the same technology as France and Japan, we could replace the coal fired plants with nuclear plants. This is proven, safe, zero CO2 emission technology. The (all-in) cost is very close to that of coal ($28 vs $29), and about one third of the cost of alternative energy. This would cut the US CO2 emission from electricity generation by half. This is huge.
Cap and Trade does not even guarantee a reduction in CO2 emissions – it just provides a penalty. Hollywood and Al Gore will just pay the penalty and continue to pollute – again assuming that CO2 is pollution. Also, as with the prisoner’s dilemma, we can not control what China, India and other countries will do. They are entitled to demand the same CO2 per-capita pollution rights as the US. In this case the CO2 reduction attempt will fail.
What we’re worried about, here, is that the US government, which initiated, and continues to maintain, subsidies to ethanol producers (and, indeed, agricultural price controls in general), may pass Waxman-Markey (and keep it in place).
What ELSE would (such a) Congress do? It’s what Congress (and governments everywhere) do. It’s so utterly foolish, you can’t even (entirely) blame democracy for it.
Any time one person’s consumption means another person cannot consume as much, there is scarcity.
Laws passed by government create a forced scarcity, an institutional barrier, not a natural scarcity, and thus does not provide valuable economic information about the resource itself. Cap-and-trade won’t address any particular person’s emissions, but instead attempts to deal with it at the industry and company level–and, of course, how much emissions are permissible will necessarily be a political decision, not an economic one. Artificial scarcity creates misery without necessity.
Of course, that’s making the assumption that such emissions are, in fact, a major factor in climate change (but that’s another argument).
Michael_A._Clem: There is NATURAL scarcity anytime one person’s consumption conflicts with another. Whether government “gets the numbers right” is irrelevant to this question. Under the assumption of both authors, emitting more CO2 increases the probability of a quantity of land becoming unusable. Therefore, preventing the CO2 emission increases the future quantity of land (in a probabilistic sense). Permitting the CO2 emission decreases the future quantity of land (in a probabilistic sense).
Therefore, these uses are in conflict. Therefore, there is natural scarcity, no matter what CO2 emission limit there is. Yes, you may prefer one party over another, but that doesn’t mean there’s no scarcity. Please do not blur the separate issues in an attempt to save face.
The problem with the carbon tax isn’t that we shouldn’t tax carbon, it is that is shouldn’t be an “added” tax.
The income tax raises about a trillion plus per year. We should simply eliminate the income tax and replace it with a carbon tax that raises a trillion. The feds don’t deserve a trillion but it would never get done otherwise.
There should be no “trading”, simply tax carbon at the source, just as it exists in the ground, keeping it simple.
There is no need for “greenhouse” logic. If we help the climate, so be it, but it doesn’t need to be the reason.
The reason is the income tax is immoral. A tax on carbon, on the other hand, would raise revenue by taxing that which is not produced. Everyone has a right, as individuals not in the collective sense, to the resource since no one produced it. Individuals [or corporations] can “purchase” that right from everyone else and the carbon tax is a good way.
One of the main austrian criticisms of socialism is the lack of pricing. Well, resources suffer the same fate. They are not priced in any market sense, they are doled out by the state at a huge discount. How can we have a free market system when the basic resources, building blocks of any product, are not priced?
If we clean up the environment at the same time, all the more reason.
No income tax, simple carbon fee, no carbon trading.

It also makes farming land more productive and more valuable. Also, the beachfront property in the Hamptons will be replaced by new beachfront property inland, which will increase in value. Also, salt water crops can be grown on low lying land that becomes inundated.
Also, in the model you are assuming is correct, unless we roll back CO2 to pre-industrial revolution levels atmospheric CO2 levels will keep increasing, so at best we would be postponing the inevitable. There is nothing special about CO2 produced in the US. The sea level rise due to CO2 produced in China and India would not be confined to the coastline of China and India.
Rising sea levels need not be catastrophic. Much of the arable land in the Netherlands is below sea level.
“Paul Krugman is a very sharp guy, conversant in many different fields. Yet his analysis of the economics of climate change is as wrongheaded as his analysis of depressions.”
The first sentence was a peculiar and unnecessary in your closing arguments.
How can he be a very sharp guy if two of the disciplines you cite (climatology and economics) demonstrate his flawed logic and poorly constructed opinion? And one of those is his career focus, to boot!
“It’s most interesting to me that these climate screamers never consider that future entrepreneurs might figure out something that solves the (perceived in this case) problem with a little smarts. Can you imagine how wealthy one could become if they solve this ‘problem’.” – Eric.
Didn’t you just answer your question? Problems don’t get perceived as problems therefore nothing get done. (Retooling isn’t something that people want to do for the fun of it.)
There is NATURAL scarcity anytime one person’s consumption conflicts with another. Whether government “gets the numbers right” is irrelevant to this question.
Who’s blurring the issue, you or me? Krugman’s article was written to advance a cap-and-trade scheme that would put politics in front of economics, but he tries to argue that it would really provide economic incentives (“market-based carbon trading”), when all it would really provide is political incentives and no good economic feedback.
Whatever natural scarcity may exist in these emissions is the separate question that you are trying to mix into the discussion, because cap-and-trade can’t truly address that natural scarcity.
One of the main austrian criticisms of socialism is the lack of pricing. Well, resources suffer the same fate. They are not priced in any market sense, they are doled out by the state at a huge discount. How can we have a free market system when the basic resources, building blocks of any product, are not priced?
gene, I can think of a few cases where a natural resource is underpiced because of government, like federal woodlands, but I don’t see most natural resources being handled that way, just some.
But this tax of yours on carbon sounds very Georgist, and just as flawed. Natural resources ARE priced, by the costs of extracting and utilizing them, if nothing else–any government tax is just an additional price on top of that.
Trading carbon can’t address natural scarcity but taxing it can.
First, we need to eliminate the tax that ruins economic feedback, the income tax.
Then tax carbon to an equal amount or less [good luck with the less part!].
Those who use will be paying for the use of the resources to those who don’t use or don’t use as much. It solves the natural scarcity issue that occurs with any natural resource.
But, I couldn’t be for simply adding another tax, michael is right in that it is simply a political ploy. if they really wanted reform, they would be offering to “trade” taxes, not carbon.
Hi Mike,
Resources owned by the state are all doled out in a collectivist manner. Take gas for instance. Can you or I go out and dig a hole on federal land and pump some natural gas? No, the feds set up a restrictive auctioning process that allows a few selected corporations vie for the rights, exactly like they dole out “new money” from the federal reserve.
Money should be made on the processing and it will or no one will buy the resource. The tax is to “price” the resource not the process.
It gets down to whether we view “state” property as common property or collective. If we view it as collective then things are fine the way they are. If it is common, then things should change.
I think it is worth clearing something up-carbon dioxide, in the cap-and-trade system or any other related “carbon legislation”, is not a natural resource that companies can access, but a byproduct of their production of something else, such as electricity. Taxing carbon dioxide does not create a price for a natural resource, but rather increases the cost of business.
While usually wrapped in environmental crusader-talk, “carbon legislation” is aimed at eliminating small competitors of big business because big business (a) wants to destroy competition and (b) is easier for the government to control.
A population of yeast placed in a bottle with some sugared water will multiply until the sugar begins to run out. They then die in their own detritus (alcahol).
Sounds remarkably like what is happening to us humans. The same thing is happening right now, but most people, including almost everyone on this blog, cannot see it.
Are we really any smarter than yeast?
It gets down to whether we view “state” property as common property or collective.
Neither. It’s not legitimately claimed by anyone.
Friends don’t let friends do Georgism.
Hi Thinker, excellent thinking!
That’s all the cap and trade is, the government working with the mega corporates to squash the little guy out and eliminate competition.
It should be taxed or priced at extraction. It is simply a cost for the right to use what wasn’t produced by anyone. Governments do not have the rights to the resource except in a Socialistic system, which is what we have. A collective, the government, deciding who to privlege with the resource.
RWW,
I agree, no property can be “legitimately” claimed without “government”.
I am all for anarchy, but that is a different universe.
SailDog
You have good company. Didier Sornette, developed a methodology to identify bubbles, by calculating the implied time something takes to double.(This time is the equivalent of the half-life concept for processes that decay over time). A monotone decrease in the doubling time signifies a bubble. So far, this methodology has worked for the NASDAQ bubble in 2000, the real estate bubble, and the oil and natural gas price bubbles that occurred last year. Currently, world population growth fits the pattern of growth for a bubble.
@SailDog
lol
It’s most interesting to me that these climate screamers never consider that future entrepreneurs might figure out something that solves the problem with a little smarts.
Gene, explain to me how any tax can be moral. All taxes are evil, and theft, and I can’t see why stealing because you have money(income tax, verse stealing because you own land (property tax), stealing because you consume(consumption tax), to stealing because carbon dioxide was created. It’s all stealing, and I honestly can’t see how any one theft is on a higher moral plane.
“A tax on carbon, on the other hand, would raise revenue by taxing that which is not produced. Everyone has a right, as individuals not in the collective sense, to the resource since no one produced it. Individuals [or corporations] can “purchase” that right from everyone else and the carbon tax is a good way.” -Gene
How is it that they are taxing on that which isn’t produced, it is supposed to tax the carbon produced?
Also I don’t understand why your against trading of carbon emissions. If it cost a company 100 fed notes, to reduce a ton of carbon dioxide, and me only a dollar, why can’t the company pay me to reduce carbon emissions. Otherwise we have a very inefficient mechanism for lowering emissions.
Sail dog, lol. Typical one step logic. We use resources, we have limited amount of them, therefore we will out of them all and die. I hope that this isn’t your view, but thats what I extrapolated fromt he analogy.
Matt-Indeed all taxes are immoral, but it just so happens that a carbon tax is particularly insidious because carbon dioxide is a natural byproduct of aerobic respiration, which humans use to live. Fortunately, most pieces of legislation are aimed solely at business, and I don’t think we’ll be reminding the people in Washington that carbon dioxide is produced by breathing-they have enough ways to enslave us as is.
Hi Matt,
First, I will agree that all taxes, forced contribution, are immoral.
So, like I mentioned, anarchy is fine but it just isn’t happening right now.
I mentioned taxing at the “source” [the resource as it comes out of the ground], not the emission, although carbon content can be used to set the rate, if that worked. I am against “trading” because if we are viewing carbon emission as “harm”, it isn’t “legitimate” to “trade” harm. If it isn’t harm, why are we taxing the emission? and like thinker mentioned, cap and trade is being used to lose the smaller players.
If we have taxes and if they are to support government which makes it possible to have “property” and a society, not to mention all the lousy things government does, we must have a tax. income tax is the worst, taxing produced goods, etc.
Resources, as they lie in the ground, are not products. No human has produced them. Everyone has a right to them, not only state privleged individuals and corporations. So, taxing extraction simply transfers that right the best way we have at the moment. It simply becomes a “cost” of extraction, sets the basic price and everyone who consumes at the end point pays for the right to use to those who don’t consume or consume less, etc.
In a perfect world, we could have a more direct transfer without government.
I can understand the “no tax” approach but it has to correlate with the no government approach also. But, if that is the case, what is the point of a tax [or carbon] discussion? wouldn’t it be more “practical” just to start planning the “revolution”? They have nukes, they are not going down easy!
