Economics and Armchair Psychology

By John Kozy

“Economics is haunted by more fallacies than any other study known to man.”― Henry Hazlitt

Over millennia, numerous enterprises have sought the status of science. Few have succeeded because they have failed to discover anything that stood up to scrutiny as knowledge. No body of beliefs, no matter how widely accepted or how extensive in scope, can ever be scientific.

In the Ptolemaic system of astronomy, the epicycle is a geometric model of the solar system and planetary motion. It was first proposed by Apollonius of Perga at the end of the 3rd century BCE and its development continued until Kepler came up with a better model in the 17th century, and the geocentric model of the solar system was replaced by Copernican heliocentrism. In spite of some very good approximations to the problems of planetary motion, the system of epicycles could never get anything right.

"Fear the Boom and Bust" a Hayek vs. Keynes Rap Anthem

Econstories.tv is a place to learn about the economic way of thinking through the eyes of creative director John Papola and creative economist Russ Roberts.

In Fear the Boom and Bust, John Maynard Keynes and F. A. Hayek, two of the great economists of the 20th century, come back to life to attend an economics conference on the economic crisis. Before the conference begins, and at the insistence of Lord Keynes, they go out for a night on the town and sing about why there's a "boom and bust" cycle in modern economies and good reason to fear it.

The Errors of Keynes's Critics

 by Steven Kates

I was intrigued by the review that Philipp Bagus wrote of The Errors of Keynes (Los Errores de la Vieja Economía), a book written in Spanish by Juan Ramón Rallo, part of which deals with Say’s Law.
An important understanding is taking hold, that the road to unwind Keynesian economics travels through Say’s Law. Keynes himself could not have been clearer about the significance of Say’s Law to the entire structure of his argument. Keynes emphasized, over and over again, in The General Theory (TGT) that he was reversing the conclusions of those who believed Say’s Law to be true. Thus, there are two things that need to be done if you are going to refute Keynes. First, you have to know what Say’s Law is. Then you have to show it is valid.

The paradox of choice

By Alasdair Macleod

Here is a puzzle for Keynesian and other neo-classical economists.
When a consumer buys something, he must choose; and if he increases his purchase of one product, he must reduce his purchases of other products by the same amount. In other words he cannot buy both. This must be true for whole communities as well. How then can you have economic growth?
It is of course impossible without monetary inflation. This is because any statistical average, in this context GDP, can only grow if people are not forced to choose between alternatives, a condition that can only occur if they are given extra money. Not even a draw-down on savings to spend on consumption creates extra spending, because it is merely reallocates spending on capital goods to consumption goods. This simple point has been ignored by all neo-classical economists. The result is that in their pursuit of so-called economic growth, they have committed themselves to monetary inflation. Their concept of growth is to make that extra money available to consumers, so that they are not limited to what they earn and forced to choose. It has also become the basis for economic modelling, which takes known demand for products and services and from it extrapolates growth for an average of all of them.

Paul Krugman's Dangerous Misconceptions

How to Deal with Economic History

 

In a recent article at the NYT entitled 'Incredible Credibility', Paul Krugman once again takes aim at those who believe it may not be a good idea to let the government's debt rise without limit. In order to understand the backdrop to this, Krugman is a Keynesian who thinks that recessions should be fought by increasing the government deficit spending and printing gobs of money. Moreover, he is a past master at presenting whatever evidence appears to support his case, while ignoring or disparaging evidence that seems to contradict his beliefs.

Among the evidence he ignores we find e.g. the 'stagflation' of the 1970's, or the inability of Japan to revive its economy in spite of having embarked on the biggest government deficit spending spree ever in a modern industrialized economy. Evidence he likes to frequently disparage is the evident success of austerity policies in the Baltic nations (evident to all but Krugman, one might say).

As readers of this blog know, we are generally of the opinion that it is in any case impossible to decide or prove points of economic theory with the help of economic history – the method Krugman seems to regularly employ. This is why we listed the evidence he ignores or disparages: the fact that there exists both plenty of evidence that contradicts his views and a much smaller body of evidence that seems to support them at an unreflected first glance, already shows that the positivist approach to economic theory must be flawed.

An economist must in fact approach things exactly the other way around, but then again it is a well-known flaw of Keynesian thinking in general that it tends to put the cart before the horse (examples for this would be the idea that one can consume oneself to economic wealth instead of saving and investing toward that goal, or that employment creates growth; it is exactly the other way around in both cases).

What the Road to Hell is Paved With....

by Bill Bonner

Improving the world costs money. When you have it, your efforts either bear fruit. Or they don’t. But when you don’t have it, when you have to change the world on credit, then what?

John Maynard Keynes revolutionized the economics profession in the early 20th century. It was he more than anyone who changed it from a being a refuge for observers and willowy philosophers into a hard-charging phalanx for men of action. But Keynes’ big insight, like all the useful insights of economics, was based on a story with a moral.

In the Book of Genesis, Pharaoh had a dream. In it, he was standing by the river. Out came 7 fat cattle. Then, 7 lean cattle came up out of the river and ate the fat cattle. A similar dream involved ears of corn, with the good ones devoured by the thin ears.

Pharaoh was troubled. His dream interpreters were stumped. So, they sent for the Hebrew man who was said to be good at this sort of thing — Joseph. Pharaoh described what had happened in his dreams. Without missing a beat, Joseph told him what they meant. The 7 fat cattle and 7 fat ears of corn represented years of plenty with bountiful harvests. The 7 lean cattle and thin ears of corn represented years of famine. Joseph wasn’t asked his opinion, but he gave his advice anyway: Pharaoh should put into place an activist, counter-cyclical economic policy. He should tax 20% of the output during the fat years and then he would be ready with some grain to sell when the famine came. Genesis reports what happened next:
