Real-World Economics Review

from Christian Arnsperger and Yanis Varoufakis Unsophisticated critics often identify economic neoclassicism with models in which all agents are perfectly informed. Or fully instrumentally rational. Or excruciatingly selfish. Defining neoclassicism in this manner would perhaps be apt in the 1950s but, nowadays, it leaves almost all of modern neoclassical theory out of the definition, therefore strengthening the mainstream’s rejoinders. Indeed, the last thirty years of neoclassical...

from Dean Baker John Quiggin had a good piece in the NYT, pointing out how the sky-high valuations of Bitcoin undermine the efficient market hypothesis that plays a central role in much economic theory. In the strong form, we can count on markets to direct capital to its best possible uses. This means that government interventions of various types will lead to a less efficient allocation of capital and therefore slower economic growth. Quiggin points out that this view is hard to...

from Lars Syll For the vast majority of scientists, thermodynamics had to be limited strictly to equilibrium. That was the opinion of J. Willard Gibbs, as well as of Gilbert N. Lewis. For them, irreversibility associated with unidirectional time was anathema … I myself experienced this type of hostility in 1946 … After I had presented my own lecture on irreversible thermodynamics, the greatest expert in the field of thermodynamics made the following comment: ‘I am astonished that this...

from Dean Baker With the Super Bowl now behind us, America eagerly awaits the next big event: the announcement of the winner in Jeff Bezos’ contest to determine which combination of state and local governments is prepared to give him the most money to be home to Amazon’s new headquarters. Narrowed from a field of more than 200 applications, 20 finalists now wait with baited breath for the news, expected sometime later this year. But while the politicians who join Bezos for the photo op...

from David Ruccio According to the Tax Justice Network, the United States ranks second in the 2018 Financial Secrecy Index. This is based on a secrecy score of 59.8, which is practically unchanged from 2015. The only country ahead of the United States is Switzerland, with a secrecy score of 76. The rise of the United States continues a long-term trend, as the country was one of the few to increase their secrecy score in the 2015 index.   The continued rise of the United States in the...

from Lars Syll Probabilistic reasoning in science — especially Bayesianism — reduces questions of rationality to questions of internal consistency (coherence) of beliefs, but, even granted this questionable reductionism, it’s not self-evident that rational agents really have to be probabilistically consistent. There is no strong warrant for believing so. Rather, there is strong evidence for us encountering huge problems if we let probabilistic reasoning become the dominant method for...

from Dean Baker That one is apparently not on the agenda, at least according to Amanda Taub’s NYT “The Interpreter” piece. The piece notes the declining support for center right and center left parties in most western democracies. While it notes that people feel unrepresented by these parties, it never states the obvious, these parties have consistently supported monetary, fiscal, trade, and intellectual property policies that redistribute an ever-larger share of income to people like...

from Michael Hudson             If mathematics is deemed to be the new language of economics, it is a language with a thought structure whose semantics, syntax and vocabulary shape its user’s perceptions. There are many ways in which to think, and many forms in which mathematical ideas may be expressed. Equilibrium theory, for example, may specify the conditions in which an economy’s public and private-sector debts may be paid. But what happens when not all these debts can be paid?...

from Lars Syll McNees documented the radical break between the 1960s and 1970s. The question is: what are the possible responses that economists and economics can make to those events? One possible response is that of Professors Lucas and Sargent. They describe what happened in the 1970s in a very strong way with a polemical vocabulary reminiscent of Spiro Agnew. Let me quote some phrases that I culled from the paper: “wildly incorrect,” “fundamentally flawed,” “wreckage,” “failure,”...

from Herman Daly By definition this is the transition from a human population maintained by high birth rates equal to high death rates, to one maintained by low birth rates equal to low death rates, and consequently from a population with low average lifetimes to one with high average lifetimes. Statistically such transitions have often been observed as standard of living increases. Many studies have attempted to explain this correlation, and much hope has been invested in it as an...
