"One should now ask how the present mess came into being. For macroeconomics today is in a state which astronomy would be if Ptolemaic theory once again came to dominate the field. There can be few instances in other disciplines of such a determined turning back of the clock. A great deal of what is written today as well as the policy recommendations which have been made would be thoroughly at home in the twenties. So something needs explaining and I hope that some good intellectual historian will attempt to do so soon." -- Frank Hahn (1985) (as quoted in Philip Mirowski's More Heat Than Light, p. 411).Do I need to note some economists today would still find Hahn's opinion apposite?
