Why economics is an impossible science
In a word, Economics is an Impossible Science because by its own definition the determining conditions of the economy are not economic: they are “exogenous.” Supposedly a science of things, it is by definition without substance, being rather a mode of behavior: the application of scarce means to alternative ends so as to achieve the greatest possible satisfaction—neither means, ends, nor satisfaction substantially specified.
Exogenous, however, is the culture, all those meanings, values, institutions, and structures, from gender roles, race relations, food preferences, and ethnicities, to technical inventions, legal regulations, political parties, etc., etc. The effect is a never-ending series of new theoretical breakthroughs, each an Economics du jour worthy of a Nobel prize, consisting of the discovery that some relevant little bit of the culture has something to do with it. Only to be soon superseded and forgotten since the continuous development and transformation of the culture, hence of the economy, leaves the Science in its wake. An impossible Science, by its own premises.
The increasing mathematization of economics has made mainstream economists more or less obsessed with formal, deductive-axiomatic models. Confronted with the critique that they do not solve real problems, they often react as Saint-Exupéry’s Great Geographer, who, in response to the questions posed by The Little Prince, says that he is too occupied with his scientific work to be able to say anything about reality.
Confronting economic theory’s lack of relevance and ability to tackle real problems, one retreats into the wonderful world of economic models. One goes into the “shack of tools” — as my old mentor Erik Dahmén used to say — and stays there. While the economic problems in the world around us steadily increase, one is rather happily playing along with the latest toys in the mathematical toolbox.
Modern mainstream economics is sure very rigorous — but if it’s rigorously wrong, who cares?
Instead of making formal logical argumentation based on deductive-axiomatic models the message, we are better served by economists who more than anything else try to contribute to solving real problems. The motto of John Maynard Keynes is as valid as ever:
It is better to be vaguely right than precisely wrong
