from Lars Syll The model has more and more become the message in modern mainstream economics. Formal models are said to help achieve ‘clarity’ and ‘consistency.’ Dani Rodrik — just to take one prominent example — even​ says, in his Economics Rules, that “models make economics a science.” Economics is more than any other social science model-oriented. There are many reasons for this — the history of the discipline, having ideals coming from the natural sciences (especially physics), the...

Brazil is falling under an evil political spell. The leading candidate in the presidential election is Jair Bolsonaro, an extreme right-wing politician. It is as if voters are sleepwalking their way to destruction of Brazilian democracy. Under the spell’s influence, they have become blind to the truth about Brazilian politics and blind to their better [...]

How did this ever pass the peer-review procedure… In an article in the Journal of Political Economy Edward Prescott and Finn Kydland argue in favor of (undemocratic) rules instead of (democratic) economic policies. One of the methods they use to push their idea is the using examples. One particular famous one is the one about floodplains. But the example is wrong. Government policies are not as benevolent, rational and effective as Prescott and Kydland think they are. And people are not...

from Asad Zaman and the current issue of the RWER In the wake of the Global Financial Crisis, the failure of economic theories, and of economists, to provide any warnings, analysis, or remedies, became glaringly obvious to all. The Queen of England went to the London School of Economics to ask “Why did no one see it coming?”. The US Congress constituted a committee to investigate why “economics, a field that aspires to be a science … (but) … generally accepted economic models inclined the...

from Lars Syll  In practice, what math does is let macro-economists locate the FWUTVs [facts with unknown truth values] farther away from the discussion of identification … Relying on a micro-foundation lets an author say, “Assume A, assume B, …  blah blah blah … And so we have proven that P is true. Then the model is identified.” … Distributional assumptions about error terms are a good place to bury things because hardly anyone pays attention to them. Moreover, if a critic does see that...

from Peter Radford I have become quite a fan of David Ciepley this summer.  He, amongst many I am sure, is blazing a trail through the morass of corporate law and providing new insights into the role and status of the animal we know as the “corporation”. Anyone with an interest in the role business plays in the economy needs to understand what Ciepley is saying. In one talk he gave, at MacGill University, the introductory remarks by his host were illumination in themselves.  The occasion...

from Lars Syll Among Swedish economists, Paul Romer has for many years been the favourite candidate for receiving the ‘Nobel Prize’ in economics. This year the prediction turned out right. Romer got the prize (together with William Nordhaus). The ‘Nobel prize’ in economics has almost exclusively gone to mainstream economists, and most often to Chicago economists. So how refreshing it is that we for once have a winner who has been brave enough to openly criticize the ‘post-real’ things...

“The fundamentals and future of the U.S. economy remain incredibly strong.” As Sandwichman always says, “when they’re telling you ‘the fundamentals are sound,’ they are unloading.”

from David Ruccio Two giants of mainstream economics—Joseph Stiglitz and Lawrence Summers—have been engaged in an acrimonious, titanic battle in recent weeks. The question is, what’s it all about? And, even more important, what’s at stake in this debate? At first glance, the intense, even personal back-and-forth between Stiglitz and Summers seems a bit odd. Both economists are firmly in the liberal wing of mainstream economics and politics—as against, for example, Gene Epstein (an...
