from John Locke The problem, however, is not the failure of economic departments and business schools to create a prescriptive science, but the refusal of nomothetic neoclassical economists and mathematical modelers in them to admit the failure, and their actions after they gained a monopoly of the sinews of institutional power, that produced dysfunctionality in Anglo American higher education. That dysfunctionalism is expressed in their constant battle with people in academia who realize...

from Michael Joffe This perspective contrasts with standard neoclassical theory in several respects. That theory puts forward models relating to the decision making of (potential) workers, and of firms – respectively the supply of and the demand for labor. Workers choose whether or not to accept employment, based on a comparison of the offered wage with their reservation wage. Firms’ decision making is seen as a comparison between employing one more or one fewer worker with the difference...

from Bernard Guerrien  One of the most widespread myths in economics, but also in sociology and political science, is that game theory provides “tools” that can help solve concrete problems in these branches – especially in economics. Introductory and advanced textbooks thus often speak of the “applications” of game theory that are being made, giving the impression that they are revolutionizing the social sciences. But, looking more closely, we see that the few examples given concern...

from Lars Syll Model builders face a constant temptation to make things more complicated than necessary because this makes them appear more capable than they really are. Remember that a model is not the truth. It is a lie to help you get your point across. And in the case of modeling economic risk, your model is a lie about others, who are probably lying themselves. And what’s worse than a simple lie? A complicated lie.

from Lars Syll A classic demonstration of group intelligence is the jelly-beans-in-the-jar experiment, in which invariably the group’s estimate is superior to the vast majority of the individual guesses. When finance professor Jack Treynor ran the experiment in his class with a jar that held 850 beans, the group estimate was 871. Only one of the fifty-six people in the class made a better guess. There are two lessons to draw from these experiments. First, in most of them the members of...

The REAL Trump pee-tape was a urine sampling pyramid scheme. “Whatever happened to Trump neckties?” asks  Zane Anthony, Kathryn Sanders and David A. Fahrenthold at the Washington Post, “They’re over. So is most of Trump’s merchandising empire.” Among the products that Trump lent his name to, for a fee, was a vitamin supplement, supposedly custom formulated based on the results of a urine test: “Take a snapshot of the most critical metabolic markers in...

from Peter Radford Paul Ryan is leaving Congress. Before he had finished announcing his upcoming retirement the airwaves were awash with commentary about his legacy. Count me as one of those who have a particularly strong perspective on this. Paul Ryan was, and presumably still is, a supremely hypocritical human being. Recall how he sprang into public consciousness. He quickly established himself as a severe right winger, but one with the smarts to back it all up. He promoted himself as a...

I am posting this NPR Fresh Air radio article here because it talks about a part of our society that has not been talked about much.  When it comes to discussion of taxation, social programs, how our economy works, the basic premise of free market misses an awful lot. From the page: For many poor families in America, eviction is a real and ongoing threat. Sociologist Matthew Desmond estimates that 2.3 million evictions were filed in the U.S. in 2016 — a...

from Dean Baker We all know about the skills shortage Harvard has to pay investment managers millions to lose the school a fortune on its endowment, Facebook can’t find a CEO who can avoid compromising its customers’ privacy, and restaurant managers apparently don’t understand that the way to get more workers is to offer higher pay. The NYT gives us yet another article complaining about labor shortages. The complaint is that restaurants have small profit margins and therefore can’t afford...
