The Education of Economists: plus ça change, plus c'est la même chose

What’s Wrong with the Economy—and with Economics?
VI. 2:30–4:00 pm: The Education of Economists
Professor Jefferson Cowie, Cornell University
Jeff Madrick, Century Foundation, New York, Editor of ‘Challenge’ Magazine
If Sandwichman was on that panel tomorrow afternoon, he would share with the audience two accounts of the education of economists, one by Larry Summers from a few weeks ago and one by John Kenneth Galbraith from 1975. All that appears to have changed from the 1930s to the 1960s was that rejection of the Luddite (etc.) fallacy was substituted for acceptance of Say's Law as the test of respectability and the 'crackpots' who didn't go along were replaced by 'a bunch of goofballs.'

First, Galbraith:
Until Keynes, Say's Law had ruled in economics for more than a century. And the rule was no casual thing; to a remarkable degree acceptance of Say was the test by which reputable economists were distinguished from the crackpots. Until late in the '30s no candidate for a Ph.D. at a major American university who spoke seriously of a shortage of purchasing power as a cause of depression could be passed. He was a man who saw only the surface of things, was unworthy of the company of scholars. Say's Law stands as the most distinguished example of the stability of economic ideas, including when they are wrong. 
 ...when I was an undergraduate at MIT in the 1960s there as a whole round of concern about this -- will automation displace all the employment? And what I was taught as an undergraduate was that basically the people who thought it would were a bunch of idiot Luddites and that obviously there would eventually be enough demand and it would all sort of work itself out, and if people got more productive they'd be richer and they'd spend and maybe we needed some transition assistance, but that it was all basically going to be okay. That was what I was taught. That's what Bob Solow thought; he was a hero and the other people were all a bunch of a goofballs was kind of what I learned. (Laughter) 
I actually believed that for many years and actually repeated it often.
Today it's much simpler. The dogma is so deeply embedded in the models and their microfoundations it doesn't have to be explicitly accepted or even acknowledged..The goofballs and crackpots are called "heterodox."
