The book’s treatment of global warming was so amazing that I picked up some HTML (thanks Barb!!!) and brought their text onto the web, along with an email exchange with the authors, emails from the publisher, and a postscript. Read on and enjoy!

Ruffin and Gregory’s text on global warming

From Ruffin, Roy J. and Paul R. Gregory, Principles of Microeconomics, 7th Edition (Boston: Addison Wesley, 2001), p. 380.

Example 5: Global Warming—The Great Debate

The debate over global warming shows that no matter how much contrary evidence is presented, it does not matter. The popular sentiment by politicians, the press, and educators makes three disputable claims: (1) global warming is occurring, (2) global warming is caused by our consumption of fossil fuels, and (3) global warming is bad for our future. But every single one of these claims is disputed by reputable scientists. For example, the earth has gotten warmer over the past 300 years, but it is still on a cooling trend over the past several thousand years. A warm 1999-2000 winter is hardly conclusive scientific proof. Indeed, when a “scientific consensus” for global warming is presented in the press, that consensus is based on a group consisting largely of social scientists and educators who have no direct knowledge of climate science. There are in fact very few climatologists in the United States, and the majority of them are skeptical of global warming.

Most of the evidence for global warming is really based not so much on measurements but on models of global warming that predict it will occur. These predictions, however, have been systematically biased upward; each year the models have to be revised downward. When a model makes a false prediction, it should be rejected rather than used as a basis for policy. Actual measurements of atmospheric temperatures show no alarming trend.

It has been argued by some economists that even if global warming takes place, it may prove to be beneficial to society. Agricultural production may be stimulated, it will cost less to heat our homes, and we may spend more time fishing, swimming, and golfing.

But the biggest risk of doing something about global warming is that the costs of cutting carbon emissions will fall on the poorest members of our planet—the developing countries. Since economic development is energy intensive, raising the cost of using carbon resources will cut the economic growth rates of countries such as India and Mexico more than that of more advanced countries.

My email exchange with Ruffin and Gregory

Professors, Mr. Shea: I have received a desk copy of the 7th edition of your Principles of Microeconomics textbook, and I must say that I am astounded by your coverage of global warming. To say that “the debate over global warming shows that no matter how much contrary evidence is presented, it does not matter” is completely unprofessional, bringing to mind conspiracy theories and black helicopters rather than reasoned analysis worthy of an academic text. It also happens to be wrong, at least according to voices you should find respectable (see for example the November 16th edition of The Economist).

I encourage you (and you, Mr. Shea) to recall this textbook as misleading and untrustworthy. For my part, I am going to spread the word about your textbook and Mr. Shea’s publishing house.

Dear Mr. Bauman: Received your e-mail. I think you must misunderstand the nature of the example on global warming. When we say that the issues are “debatable,” this simply means that there are disagreements among scientists not that the notions are untrue. We’re sorry to have alarmed you so much. Global warming is a serious issue, but one that should be addressed by scientific evidence and methods rather than a pros and cons approach that we seem to see. Global warming is certainly occurring. But there are questions dealing with its solution because the models themselves still need to be worked out until their predictions fit all the facts at our disposal–this is a point we have not yet reached. As a scientist, I believe that we must use testable and fully tested models of scientific questions. There is still the problem of the difference between atmospheric temperatures and earth-based measurements, and the models have not yet addressed this difference. This does not in any way deny global warming. Perhaps we should have used the word “controversial” rather than “debatable,” but its a big book and wrong words are often used. In any case, this will give you a chance to show just how smart you are compared to the authors! Thanks for your comments; hopefully, in the next edition there will be more closure on this issue. Best regards, Roy Ruffin

Professor: Thanks for your reply. I am not at all troubled when you say that global warming is debatable; disclaimers such as “the balance of evidence suggests that…” appear everywhere. What troubles me is when you say that global warming is _not_ debatable, and that is clearly the message of your sidebar, beginning with the opening sentence: “The debate over global warming shows that no matter how much contrary evidence is presented, it does not matter.” I cannot interpret this sentence (or the sidebar as a whole) in any way that is even remotely consistent with what you say in your email (“Global warming is a serious issue…”; “Global warming is certainly occurring…”; “[We] simply mean that there are disagreements among scientists…”).

I hope that you and Professor Gregory (and Mr. Shea, your publishing representative) will recognize this inconsistency and act accordingly. Your suggestion that this “misunderstanding” could be cleared up by using the word “controversial” rather than “debatable” is quite odd, if for no other reason than that words like “debate” appear only twice in your sidebar: once in the title (“Global Warming–The Great Debate”) and once in the opening sentence (quoted above). Thereafter your sidebar features not equivocations but declarations (“There are in fact very few climatologists in the United States, and the majority of them are skeptical of global warming”). These declarations are based on a single suspect source (see my postscript below for details), appear to contain major factual inaccuracies, and are at odds with what you say in your own email.

I would suggest that your reputations as scholars (and Addison-Wesley’s reputation as a trustworthy publishing house) are at stake here in much the same way that Paul Ehrlich’s reputation was at stake in his ill-fated bet with Julian Simon. To his credit, Ehrlich at least had the honor and good sense to acknowledge his error and pay the cost. It will be to your credit if you do the same and recall your textbook.

Sincerely,
yoram bauman

PS. In your book you dismiss the “scientific consensus” on global warming as one “consisting largely of social scientists and educators who have no direct knowledge of climate science.” Yet your own sidebar is based entirely on a lecture by the director of the Cato Institute’s program on natural resources, a man who may himself have no direct knowledge of climate science. (He didn’t return my emails, so I don’t know for sure.) What I do know for sure is that some of his claims fail to stand up to scrutiny. For example, he says that “4,000+ scientists (70 of whom are Nobel Prize winners) have signed the so-called Heidelberg Appeal, which warns the industrialized world that no compelling evidence exists to justify controls of anthropogenic greenhouse gas emissions.” I have located various copies of the Heidelberg Appeal on the web (for example, at www.heartland.org); all of them feature the identical text, and that text makes no mention of greenhouse gas emissions.

Dear Mr. Baum:

Your approach does not encourage discourse on the subject of global warming. I imagine that 99 out of 100 reports that reach the general public assert without doubt that global warming exists and will have dire consequences. When we cite an article that states that this may not be true, we are labelled as seeing “black helicopters” and declared “ignorant.” We may reach the point soon where anyone who raises such questions will be penalized and punished. It is rather extreme to ask the withdrawal of a book that consists of almost 800 pages of good economic analysis because of a sentence that you disagree with. The offending sentence simply says that contrary evidence has been and continues to be ignored.

I truly hope that this is not your position. If so, it does discredit to the position that you espouse and suggests a witchhunt.

Professor: Thank you for your email. At some point I hope that you and your coauthor can move beyond denial and anger and reach acceptance. What I hope you will accept is this:

1. It is not scholarly to say things like “I imagine that 99 out of 100 reports that reach the general public assert without doubt that global warming exists and will have dire consequences.” Academic discourse, and especially academic publications, should meet a higher standard than that found in the media, and a much higher standard than that found in our imaginations.
2. It is your approach, not mine, that “does not encourage discourse on the subject of global warming.” It is your writings, not mine, that claim that “the debate over global warming shows that no matter how much contrary evidence is presented, it does not matter.” It is your text, not mine, that dismisses contrary viewpoints. And, though it was my email that raised concerns about seeing black helicopters, it is your text and your email that highlight those concerns by asserting a scientific conspiracy, by imagining a media conspiracy, and by seeing a witchhunt when in truth there are only tough questions and solid criticisms.
3. I am asking for the withdrawal of your textbook because I see no better option. An errata sheet would be fine, but I don’t think that you or your publisher would support something that focuses attention on your sidebar, and in any case I doubt that a suitable message exists for such an errata sheet: a “clarification of intent” would be duplicitous, and a substantive clarification would be too uncomfortable. The only other alternative that I see is to sweep it under the rug and make changes in your next edition, but I hope that you and your publisher will find this dishonorable and distasteful.

Finally, I must point out that I have never declared you to be “ignorant”, and I do not intend to. I think you have made a mistake, and I hope you take appropriate steps to acknowledge and correct that mistake.

Sincerely,
yoram bauman

Dear Mr. Bauman:

Thank you for your message and for your concern about our coverage of this issue. I will let you know the outcome of our discussions. It would be helpful if you could send to me (in a single email, if possible) the comments that you have gathered from climate scientists. I do not doubt the validity of your point of view, but having informed opinions from scientists may come in handy. Is there a chance that you could forward these to me by Monday afternoon?

I appreciate your willingness to assist us. I will be in touch soon.

Postscript

Many thanks to all those who took the time to write to Ruffin and Gregory and/or to me about this issue–it seems like we’ve had some success!!! Someday I hope to come across the new printing of Ruffin and Gregory’s textbook; if and when I do I will post their updated treatment of global warming…

  • Humorous articles, such as Leijonhufvud’s “Life among the Econ”, (Economic Inquiry, 1973), Gregor W. Smith’s “Japan’s Phillips Curve looks like Japan” (Journal of Money, Credit and Banking, 2008), or my own “Principles of economics, translated”, which is available in text format (Annals of Improbable Research, 2003) or on YouTube. (See below for a semi-complete list of funny articles.)
  • News headlines, real or imagined, such as a 2004 CNN.com article that was originally headlined “Iraqis polled: War did more harm than good but worth it.”
  • Original economics jokes, such as “You might be an economist if…” Please don’t send me “assume a can-opener” or other jokes that are online, e.g., on JokEc.
  • Cartoons, anecdotes, and other funny stuff. I’ll even consider amusing excerpts from rejection letters, such as the 2003 referee report by a reviewer who failed to notice that the 20th century was over.

See the list below for my stab at a compendium of economics humor, and note some of these articles (and many others) can be found in Clotfelter’s On the Third Hand: Wit and Humor in the Dismal Science. If you have additions to this list, please let me know!

Instructions for submissions

If you have a joke or cartoon or other short piece, email it (with a subject line of “Economics miscellany”) to me at yoram@standupeconomist.com. If you have a multi-page “serious” submission, send it through the usual process, beginning with a careful read of the Submission Information. (Make sure to write on your paper that it is intended for the Miscellany section, and yes you will have to pay the submission fee.) If you are not sure whether your paper is “serious” or not, email it to me and ask me.

Funny economics articles

Please send me additions (I’m just starting this compendium), and please note that some of these articles (and many others) can be found in Clotfelter’s On the Third Hand.

The “assume a can opener” joke (from JokEc)

A physicist, a chemist and an economist are stranded on an island, with nothing to eat. A can of soup washes ashore. The physicist says, “Lets smash the can open with a rock.” The chemist says, “Lets build a fire and heat the can first.” The economist says, “Lets assume that we have a can-opener…”
