Real-World Economics Review

from Lars Syll Causal inferences can be drawn from nonexperimental data. However, no mechanical rules can be laid down for the activity. Since Hume, that is almost a truism. Instead, causal inference seems to require an enormous investment of skill, intelligence, and hard work. Many convergent lines of evidence must be developed. Natural variation needs to be identified and exploited. Data must be collected. Confounders need to be considered. Alternative explanations have to be...

from Peter Radford There is a new eBook published by the Stigler Center which is an offshoot of the Booth Business School at the University of Chicago.  The publication contains a number of short essays either attacking or defending the infamous pronouncements by Milton Friedman on the role of the corporation.  This year, you may recall, is the 50th anniversary of the newspaper article in which Friedman described his view that the purpose of the corporation is too maximize shareholder...

from Lars Syll How, then, can social scientists best make inferences about causal effects? One option is true experimentation … Random assignment ensures that any differences in outcomes between the groups are due either to chance error or to the causal effect … If the experiment were to be repeated over and over, the groups would not differ, on average, in the values of potential confounders. Thus, the average of the average difference of group outcomes, across these many experiments,...

from Dean Baker When I do one of my diatribes about how our protectionist barriers allow U.S. doctors to earn twice as much as doctors in other wealthy countries, I invariably get complaints from doctors and their friends asking why I don’t go after the really big bucks people on Wall Street. The answer of course is that I do, but the bloated paychecks on Wall Street are not a reason to pay an extra $100 billion a year ($750 per household) to doctors in the United States. But it is true...

from Lars Syll Modern econometrics is fundamentally based on assuming — usually without any explicit justification — that we can gain causal knowledge by considering independent variables that may have an impact on the variation of a dependent variable. This is however, far from self-evident. Often the fundamental causes are constant forces that are not amenable to the kind of analysis econometrics supplies us with. As Stanley Lieberson has it in Making It Count: One can always say...

from Asad Zaman Among the many dimensions I have listed in “New Directions in Macroeconomics”, the most important is the moral dimension. If we take Adam Smith as the founder, economics was born as a branch of moral philosophy. However, modern economists claim that the subject is purely positive and scientific, and makes no value judgments. Before we can discuss moral dimensions of economic theories, we must counter this claim, and establish that, contrary to claims made by economists,...

from Lars Syll The “prisoner’s dilemma” is a familiar concept to just about everyone who took Econ 101 … Yet no one’s ever actually run the experiment on real prisoners before, until two University of Hamburg economists tried it out in a recent study comparing the behavior of inmates and students. Surprisingly, for the classic version of the game, prisoners were far more cooperative than expected. Menusch Khadjavi and Andreas Lange put the famous game to the test for the first time ever,...

Dean Baker from JGRMX joins Joe and Lake on this episode of Hidden Horsepower. They discuss the transition from 2 cycle engines to 4 cycles, and the talk turns to wet clutches, cams and more.

from Blair Fix It was a bet heard around the world. Okay, that’s an exaggeration. It was a bet heard mostly by academics and sustainability buffs. But still, it was a bet … and it was important. The year was 1980. The players were biologist Paul Ehrlich and business professor Julian Simon. The two had conflicting ideas about where humanity was headed. Ehrlich, the author of the 1968 book The Population Bomb, thought humanity was headed for a Malthusian catastrophe. Simon thought the...
