Why economists lie

I should start with a disclaimer, I am an economist who likes to think that I am generally honest. What I am protesting against is the tendency of many practitioners of my profession to lie. They lie when faced with problems to which they have no solution, by claiming that to have policy solutions that in practice are unrealistic or untrue. 

Rousseau in his writings used the term amour-propre, words which have many synonyms in English and they include pride, self respect and vain glory. It is the last which is a fault that afflicts so many economists. They are the self acknowledged experts on the economy and are never willing admit that they are stuck for an answer. When a problem occurs they will look for an answer from their memory bank and choose one which seems to be offer the best solution. It is not an original solution, but one borrowed from the collective memory bank of all economists. What matters to the economist is that their answer will be judged as correct by their fellow economists not that it is the correct solution to the problem posed by the economy.  Given the complexity of the economy, they can always blame the failure of their policy recommendations on unexpected events.  The familiar its somebody else’s fault excuse is always available as a defence for a failed  policy. In this case its either the fault of the economy when they claim that the fault lies with  unexpected changes in internal or international economy, or its the politicians who fail to understand the policy prescriptions and implement them wrongly. When the great reforms of the 1980s were imposed on the British economy which led to a decimation of the British manufacturing sector; economists introduced another lie, which was that the pain being endured now would lead to a better future in which a revitalised economy which would work to the benefit of all. A future which never materialised.

What I am leading is a campaign for economists to say I don’t know. A willingness to look  at each situation afresh and use the skills of economic analysis to come up with original and new solutions to economic problems. Unfortunately the majority of economists believe that the economic toolset was largely completed in the time Alfred Marshall, whose most influential book the ‘Principles of Economics’ was published in 1890. All that is now required is a tinkering with the toolset left by Marshall to develop the economic policies needed for today. (Marshall systemised the study of market economics, developing a series of tools of economic analysis which are widely used today.)

The great change in the practice of economic policy making in the 1980s was the introduction of monetary economics associated with the American economist Milton Friedman. What was not realised was that he was merely adapting the quantity theory of money which was explained in a  book published  by Irving Fisher in 1911 to the world of the 1980s? Plagiarism in economics is not frowned on but worshipped, so long as the correct work in plagiarised.

Perhaps self censorship might be a more accurate term to describe the practice to which I am objecting. However every economist when studying the subject at university will either be taught about the flaws in the dominant model of economic analysis or would have come across them in one of the texts that they have studied. Yet once they leave university to practice their profession, they suppress their knowledge of the weaknesses or flaws of the favoured method of economic analysis. The act of forgetting probably becomes second nature to the practising economist. Deliberately ignoring the evidence that might suggest that their suggested policy remedies are flawed is an act of dishonesty. Lord Oakshott the former Liberal Democrat Treasury Minister once said that the British Treasury is populated by free market fundamentalists. What he was saying was that  Treasury economists were excluding from their economic policy making any evidence or thinking that was contrary to the free market model of economic analysis. This suggests that economic policy making by the government will be constantly subject to error, because of the wilful deception practised by Treasury economists.
