Economics is a science

Every so often, the statement pops up that economics is not a science, but a product of people’s emotional reactions.

Economics, properly termed Political Economy, is a genuine science. If it were not, then there would be no point in any policy intervention as its effects would be completely unpredictable. The “Science of Political Economy” (there is a book with that title by Henry George) progressed from the time of the French Physiocrats, via Smith, Ricardo, J S Mill and Henry George, until the 1880s. After that, the basic principles were buried and covered with a smokescreen of impressive-looking mathematics.

Basic principles still apply: if prices are higher, less is sold and supply tends to increase. Then there is the Law of Rent, which every street beggar and musician knows: a busker will collect more at the bottom of the escalators at Victoria than outside the station at West Finchley. The difference is due to the advantages of location ie it is what Ricardo identified as “economic rent”. You will not find any of this in most economics textbooks and might go through an entire degree course without coming across it, but there are consistent and identifiable cause-and-effect relationships which mean that economics can legitimately be regarded as a science.

The dreadfulness of British governance

I wrote to my MP on two entirely separate issues recently. The first was to do with the replacement for the Inter City 125 train, which at £2.6 million per vehicle, is twice as expensive as it ought to be. The second concerned the benefits of a switch from business rate and Council Tax to a tax based on site values. In both cases, the replies were full of spurious, unsubstantiated assertions and completely flawed arguments. This is typical. You will not get an iota of sense from the government on any area of public policy at all - finance, economics, trade and employment, agriculture, housing, health, transport, energy. All junk. If you write to your MP you will invariably receive answers that are an insult to your intelligence, no matter what subject you are writing about. Of course they cannot understand statistics. They are innumerate. Whitehall is staffed with idiots with a high IQ. Look at their IT projects. And mind your purse, they will have that too.

How much more will the British tolerate?

The British are phlegmatic, tolerant and slow to rouse. Thus there was no great reaction after the terrorist attack in July 2005. The murder of Lee Rigby created a sense of outrage, but nothing more, since it appeared to be an isolated incident. Two serious incidents within a fortnight are another matter. Since the first major terrorist incident in 2001, authority has tried to persuade the public that Islam is a religion of peace, that these were isolated events, or the actions of deranged "lone wolves", having nothing to do with Islam, or to reassure that the chances of being killed in a terrorist attack were infinitesimally small. These assurances are are beginning to wear thin. They no longer convince. If government does not act effectively, people will take the law into their own hands. What, however, would effective action look like? What sort of effective action would not amount to rough justice for a lot of innocent people? Given the difficulties of keeping large n...

Importing people to sustain demand

I got involved in a discussion with a Youtuber called “Philosophy all along”. This was in connection with criticism of Trump’s policy of deporting illegal migrants, which he argued would be bad for the economy as it would reduce demand. This implies that there is a need to import people to sustain demand. There is no obvious reason why a population should not be able to consume everything that the same population produces. If it can not, then something else is going on. It is a basic principle that wages are the least that workers will accept to do a job. Wages are a share of the value added by workers through their wages. The remainder is distributed as economic rent, after government has taken its cut in taxes. Monopoly profit is a temporary surplus that after a delay gets absorbed into economic rent. Land values in Silicon Valley are an example of this; it's like a gold rush. The miners get little out of it. Rent and tax syphon purchasing power away from those who produce the g...
