Executive Summary: “We want others to find us good, fair, responsible and logical; and we place even more importance on thinking of ourselves this way. Therefore, when people behave in ways that might appear selfish, prejudiced, or perverted, they tend to engage a host of strategies designed to justify questionable behavior with rational excuses: “I hired my son because he’s more qualified.” “I promoted Ashley because she does a better job than Aisha.” Or, “I read Playboy for the articles.””

Boston Globe: “A huge outback dust storm – 500 km (310 mi) wide by 1,000 km (620 mi) long – swept across eastern Australia and blanketed Sydney on Wednesday, September 23rd, disrupting flights and ground transportation and forcing people indoors for shelter from the hazardous air, gale-force winds, and in some places hailstorms. Those few who ventured outside, especially at dawn, were greeted by a Martian sky, familiar landmarks blotted out by the heavy red dust blowing by. Collected here are a few photos of the worst dust storm Sydney has seen in 70 years, three of which you can click to see a before/after fade effect. (26 photos total).”

Baylor economists Grinols and Henderson on health insurance and health care reform

One month ago, I blogged about a new book entitled “ Health Care for Us All: Getting More for Our Investment” written by Baylor economists Earl Grinols and Jim Henderson (see “ Baylor University Economists Call for Different Tack on Health Care Insurance”).  I would like to call attention to guest columns by both of my colleagues that appeared this Sunday in the Waco Tribune-Herald:

  • Waco Tribune-Herald: Earl L. Grinols, guest column: A lesson on how health insurance really works
    Waco Tribune-Herald, Sept. 20, 2009 (guest column about health care reform by applying basic economic principles by Dr. Earl L. Grinols, Distinguished Professor of Economics at Baylor, and co-author of the book, “Health Care for Us All,” with Baylor economics professor Jim Henderson)Americans have expressed displeasure with House Bill 3200, “America’s Affordable Health Choices Act of 2009,” as well as a proposed Senate version still in process, because both contain bad economics and bad ideas. Yet, one cannot beat something with nothing.

  • Waco Tribune-Herald: James W. Henderson, guest column: Busting apart the big myths about health care
    Waco Tribune-Herald, Sept. 20, 2009 (guest column by Baylor economics professor James Henderson, who separates fact from fiction in the ongoing health care debate; Henderson is co-author of “Health Care for Us All” with Dr. Earl L. Grinols, Distinguished Professor of Economics at Baylor)The great enemy of the truth is very often not the lie — deliberate, contrived and dishonest — but the myth: persistent, persuasive, and unrealistic. — President John F. Kennedy, commencement address at Yale University, June 11, 1962. It’s often difficult to sort out fact from fiction in the ongoing health care debate. Both sides are exaggerating issues and torturing data to make their points. The result is often confusing and misleading.

On the use of math in economics (version 2.0)…

In response to my previous posting entitled “On the use of math in economics…”, my colleague Allen Seward pointed out the following quote to me (Attributed to Alfred Marshall; see Todd G. Buchholz, 1989, New Ideas from Dead Economists, New York: Penguin Group, p. 151.):

In a letter to his protégée, A.C. Pigou, he [Marshall] laid out the following system: “(1) Use mathematics as shorthand language, rather than as an engine of inquiry. (2) Keep to them till you have done. (3) Translate into English. (4) Then illustrate by examples that are important in real life (5) Burn the mathematics. (6) If you can’t succeed in 4, burn 3. This I do often.”

On the use of math in economics…

As I prepare my course in managerial economics, I have tried to put myself in my students’ shoes and ask why all the math?  This is a particularly relevant question because my students are enrolled in Baylor’s executive MBA program, and they (quite understandably) have no interest in becoming professional economists. 

In his recent blog entry entitled “Mathematics and Economics”, Paul Krugman notes, among other things, that “Math in economics can be extremely useful”, and that math can serve an essential analytic function by helping to clarify one’s thoughts.  Some other samplings from the economics blogosphere include the following observations:

  1. Greg Mankiw (cf. http://gregmankiw.blogspot.com/2006/09/why-aspiring-economists-need-math.html) notes, among other things, that “Math is good training for the mind. It makes you a more rigorous thinker.”
  2. Jason DeBacker (cf. http://www.econosseur.com/2009/02/why-economists-use-so-much-math.html) makes the following observations: “Math provides a common language for economic thought”, and “Math helps to quantify tradeoffs.”  He also notes that “Using math puts in plain sight the assumptions that lie behind a model and the mechanisms at work in the model”, which is consistent with Professor Krugman’s observation noted above.

However, I am also reminded of the famous quote “it is better to be vaguely right than precisely wrong” which is commonly (and incorrectly) attributed to the famous economist John Maynard Keynes. (For what it’s worth, O’Donnell (2006) notes (see p. 403, footnote 14) that “This saying so aptly captures a strand in Keynes’s thought that he is frequently, but wrongly, treated as its author”; apparently, the original source for this memorable quote was a contemporary of Keynes by the name of Wildon Carr (see Shove (1942: 323)).
