Real-World Economics Review

from Lars Syll Submission to observed or experimental data is the golden rule which dominates any scientific discipline. Any theory whatever, if it is not verified by empirical evidence, has no scientific value and should be rejected. Maurice Allais Formalistic deductive “Glasperlenspiel” can be very impressive and seductive. But in the realm of science, it ought to be considered of little or no value to simply make claims about the model and lose sight of reality. Mainstream —...

from Grazia Ietto-Gillies Digitalization has been with us for a couple of decades and is now all pervasive. It affects every sphere of economic activity: from production to consumption to the interaction between the State and its citizens. The latter interaction is in terms of: the delivery of public services; the collection of revenue; and the development and implementation of public policies. The transnational companies (TNCs) have been with us for much longer. Steven Hymer (1976...

from Lars Syll If you want to know what is neoclassical economics — or mainstream economics as we call it nowadays — and turn to Wikipedia you are told that neoclassical economics is a term variously used for approaches to economics focusing on the determination of prices, outputs, and income distributions in markets through supply and demand, often mediated through a hypothesized maximization of utility by income-constrained individuals and of profits by cost-constrained firms employing...

from David Ruccio If there ever was an argument in support of Medicare for All it’s this: despite spending more on health care than any other country, the United States has seen increasing mortality and falling life expectancy for people ages 25 to 64, who should be in the prime of their lives. A new report published in the Journal of the American Medical Association paints a bleak picture: overall life expectancy in the United States, which had increased for most of the past 60 years,...

from Lars Syll The financial crisis of 2007-08 hit most laymen and economists with surprise. What was it that went wrong with our macroeconomic models, since they obviously did not foresee the collapse or even make it conceivable? There are many who have ventured to answer this question. And they have come up with a variety of answers, ranging from the exaggerated mathematization of economics to irrational and corrupt politicians. But the root of our problem goes much deeper. It...

from Blair Fix Branko Milanović is the oracle of ancient inequality. He has muckraked to compile inequality data for many pre-industrial societies. Here’s a chart of inequality versus GDP per capita for ancient societies: Ancient Inequality Data from Branko Milanović. (Source) The curved line is the ‘inequality possibility frontier’. This is the maximum inequality that is achievable at the given level of production. I have my own ideas about what creates an inequality frontier — I think...

from Lars Syll Nobel prizes are usually given in recognition of ideas that are already more or less guaranteed a legacy. But occasionally they prompt as much debate as admiration. This year’s economics award, given to Abhijit Banerjee, Esther Duflo and Michael Kremer … recognised the laureates’ efforts to use randomised controlled trials (RCTs) to answer social-science questions … RCT evangelists sometimes argue that their technique is the “gold standard”, better able than other...

from Dean Baker This is one in the “whose is bigger?” category; which country has added the most to their GDP over the last three years. There is not any particular reason anyone should care about this, except that Donald Trump has made a big point of touting something about how no one says China will soon be the world’s largest economy anymore. In fact, China’s economy surpassed the U.S. economy in 2015, using the purchasing power parity measure of GDP. This measure, in principle, uses a...

from Blair Fix Do you think that the discipline of economics is a sham — an ideology masquerading as science? If so, here is a reading list for you. These 10 books have influenced my thinking over the years. Read them and join me in the journey of the economic heretic. 1. Capital as Power. A Study of Order and Creorder Jonathan Nitzan and Shimshon Bichler Few books offer both a compelling critique of mainstream economics and a bold alternative vision for political economy. But in...

from Lars Syll [embedded content] If anything, Snow’s path-breaking research underlines how important it is not to equate science with statistical calculation. All science entail human judgement, and using statistical models doesn’t relieve us of that necessity. Working with misspecified models, the scientific value of statistics is actually zero — even though you’re making valid statistical inferences! Statistical models are no substitutes for doing real science. Or as a German...
