Revolution and counter-revolution: two views of unemployment

There is a view in economics that Keynes did not have a microeconomictheory underpinning his explanation of macroeconomics. For example,Friedman (1970) even goes so far as to maintain that pricesare arbitrary in Keyne's approach to economics. The conclusionwhich follows from this critique of Keynes is that Keynesianeconomics cannot explain the occurrence of unemployment in amarket economy except by invoking ad hoc assumptions. It isargued in this paper that the above critique is based on a misunderstandingof the focus of the Keynesian explanation of unemployment. Thefocus in Keynes is not choice, but exclusion from choice. Inconventional microeconomics, the concept of choice is not consideredproblematic. The observation that a particular action is takenis confused with the view that the action is voluntarily chosen.The Keynesian explanation entails an exploration of what theconcept of voluntary choice means.
