Anyone who is serious about debating should know that appeals to authority are logical fallacies. I often see people appealing to the fact that Hayek got a Nobel prize, as if this should impress us, and as though it provides some support to his theories. This is nothing but an appeal to authority.
Here are some crucial points in response:
(1) The Nobel Memorial Prize in Economic Sciences is not even a proper Nobel prize at all: it was not set up by the will of Alfred Nobel in 1895. Instead, it was established by the Central Bank of Sweden in 1968.Neoclassical economics is wrong and the majority of Nobel Memorial Prize winners are neoclassicals. It follows that most of these people’s theories are probably wrong too. Some Post Keynesians have been awarded the Nobel Memorial Prize, but again this does not give any extra support to Post Keynesian economic theory.
(2) Friedrich Hayek won the prize in 1974 jointly with the Swedish social democrat Gunnar Myrdal.
(3) The overwhelming number of Nobel Memorial Prize in Economic Sciences winners are neoclassicals, neoclassical synthesis Keynesians or New Keynesian economists who reject Austrian economics, but
(4) It is neither here nor there if Hayek, Krugman or anyone else won the Nobel Memorial Prize in Economic Sciences. It doesn’t mean much.
Post Keynesian economics – just like any other economic theory – will stand or fall on the truth of its foundational assumptions and the consistency and cogency of its arguments, and, where appropriate, whether empirical evidence gives support to its theories.
