by From Lars Syll ‘Modern’ economics has become increasingly irrelevant to the understanding of the real world. In his seminal book Economics and Reality(1997), Tony Lawson traced this irrelevance to the failure of economists to match their deductive-axiomatic methods with their subject It is — sad to say — as relevant today as it was twenty years ago. It is still a fact that within mainstream economics internal validity is everything and external validity nothing. Why anyone should be interested in that kind of theories and models is beyond imagination. As long as mainstream economists do not come up with any export-licenses for their theories and models to the real world in which we live, they really should not be surprised if people say that this is not science, but autism!

Studying mathematics and logic is interesting and fun. It sharpens the mind. In pure mathematics and logic, we do not have to worry about external validity. But economics is not pure mathematics or logic. It’s about society. The real world.
Economics and Reality was a great inspiration to yours truly twenty years ago. It still is.
