      "Haiku Economics", by Stephen T. Ziliak, was cited by Poetry as one of the ten "most-read articles" of 2011.

 

       Ziliak's article, on the relation between haiku and economics, appears in the January 2011 "The View From Here" column. And according to the Associate Editor of Poetry, "Haiku Economics" is probably the most-read article in that column's history.

   [November 2nd, 2011, Cambridge, MA]

     Seventy Harvard [students]walked out of Professor Greg Mankiw's Introductory Economics class in "protest", the students said, of "the bias inherent" in his course.

"I think I would like that class."

    We at [Roosevelt University]and [INET] - the Institute for New Economic Thinking - are not surprised by student discontent, and wish to help.

    Here, for example, is a syllabus for The Grapes of Wrath course I've taught since 1996, offering a pluralistic alternative to Mankiw.

    A good protest needs a good protest novel. Steinbeck's couldn't be more relevant to the current milieu [video].

[Did the Crisis Affect My Teaching?]

      "Not much," I explain in a recent video interview.  I've always taught from conflict and crisis, starting in 1996 when I first assigned John Steinbeck's The Grapes of Wrath and Studs Terkel's Hard Times to students of economics. Tom Joad is not a simple utility maximizer, true; but he has a moral conscience and love, even better.

Economic Science Trivia Question:

   What scientific discovery was made by an economist during a routine analysis of fermentation?

 a. Oxygen, b. Carbon Dioxide, c. Chemistry's Balanced Equation and the Principle of Conservation of Mass, d. Small Sample Theory and Analysis (Statistics), e. All of the Above.

    Yes, amazingly, "e. All of the Above," is correct! The discoveries were made by Priestley (beer), Priestley (beer), Lavoisier (wine), and Gosset aka "Student" (beer), an Oxford-trained chemist who pioneered econometric theory and analysis in his job as experimental brewer of Guinness, St. James's Gate, Dublin.

          *Read Mr. Bialik's blog  

          *And the print edition

     As Mr. Bialik explains, on March 22, 2011, the Supreme Court of the United States unanimously rejected the claim by Petitioners, Matrixx,Inc., that a bright-line standard of "statistical significance" - a fixed and pre-determined level of Type I error -  is necessary for proving a fact. The Court's strong ruling against "significance" is particularly relevant to big pharmaceutical and other biomedical firms which have to report to the U.S. Securities and Exchange Commission (SEC) on "adverse effects" from product consumption.

     On November 12, 2010, McCloskey and Ziliak filed an amicus brief with the Supreme Court, explaining to the Court the difference between "statistical" significance and "practical" importance. In oral argument on January 10, 2011, Justice Sotomayor thanked "amici" for doing a "wonderful job".

      In other words, the Supreme Court agrees unanimously with a view well- established by McCloskey and Ziliak, that statistical significance is neither necessary nor sufficient for proving a commercial or scientific result.

           See Contents / Order Now 

      What does the suppression of black unemployment rates have to do with statistical significance?

      Read a blog interview to find out

 


     Expert scientists believe they're testing hypotheses with their conventional tests of statistical significance. They’re not. 

     They think the “existence” of one kind of precision under conditions of random error--namely, statistical significance--can answer the scientific, quantitative question of estimation, which is a question of “size-matters/how much.” It can’t. 

     They think the null procedure routine since Fisher can answer the pragmatic question about the distribution of reasonable degrees of belief over a range of possibly believable if radically different hypotheses. It can’t, won’t, and never will. Today’s scientist neither tests nor estimates—he “testimates.” 

                    

     "Student" (aka William Sealy Gosset, 1876-1937) worried about careless uses of his test.  He had reason to.  

      After Fisher, testimation is the outcome.  Testimation is the unhappy marriage of the fallacy of the transposed conditional to the sizeless stare of statistical significance. It is ruining the quantitative solidity of the sciences descended from Galton and Pearson and especially from Ronald A. Fisher. And its reckless policy recommendations are costing us jobs, justice, ecology, and even human lives.

     In 1908 "Student" changed some sciences with his small sample test of significance.  Now those sciences are stagnating or declining through their reckless and illogical deployments of "Student's" test, just as "Student" himself always warned they could.

       Stephen T. Ziliak is an economist whose work spans the fields of history, philosophy, rhetoric, statistics, and social policy.

       He experiments with a kind of economic poetry or criticism, too, in what he calls haiku economics - "as if economics is so efficient". He learned haiku from a friend, the late Etheridge Knight, a great American poet & haiku master:

 

Invisible hand:

Mother of inflated hope,

Mistress of despair.

 

Cooling temperatures

Teens, chilly away from Lake

Ghetto kids rejoice!

 

From first principles

you find an end-state result:

The state should stop now.

 

Corrugated steel

Fence-links cap off prison wall/

Blackbird pecks at chains.

Etheridge Knight (1931-1991)

"America's greatest poet in the oral tradition." 

       - Robert Bly to Steve Ziliak, Denoument Gallery, Indianapolis, Jan. 1991


       Ziliak earned graduate degrees from the University of Iowa in both Economics(Ph.D., 1996) and the Rhetoric of the Social Sciences (Ph.D. Certificate, 1996). A frequent collaborator with Deirdre McCloskey, Ziliak is the author or editor of three books (with McCloskey) and over sixty scholarly articles.

        An expert at historical archival research, Ziliak is best known for his work on American social welfare and on the history, theory, and practice of hypothesis testing in the life and human sciences.                  


       Ziliak has taught at a number of institutions around the United States, including Emory University and the Georgia Institute of Technology where, in 2002, he was awarded "Faculty Member of the Year" and, in the following year, "Most Intellectual Professor." He is currently Professor of Economics at Roosevelt University.

       A prize-winning teacher, Ziliak is the author of an unusual micro and macro textbook, The Economic Conversation(Palgrave/MacMillan), which aims to change the way economics is taught. Co-authored with Arjo Klamer and Deirdre McCloskey, nearly a third of The Economic Conversation is written in Socratic dialogue.        


       Ziliak's main project now is on the scientific character of William Sealy Gosset (1876-1937) aka "Student" of "Student's" t. Most scientists have learned about "Student's" t from Fisher or a Fisher disciple. This has been bad for "Student"--and science.

                

      Fisher misled some sciences in the 20th century. From the very beginning, in 1904, "Student" took an economic approach to the logic of uncertainty. Karl Pearson, and then especially Ronald Fisher, wouldn't listen to "Student." In the 1920s and 1930s Gosset, this "Student," improved upon his own economic approach, inventing the statistical ideas of power and loss, which he gave to Egon S. Pearson and Jerzy Neyman to formalize. Gosset was in these and other regards a great scientist. His economic approach to for example the test of statistical significance and the statistical design of experiments can repair the damage done in science and policy by today's Fisherian methods.
