ABSTRACT
This paper examines the issue of how Don Patinkin, a scholar’s scholar, could have gone so far astray in his periodic assessments of that part of Keynes’s Theory of Effective Demand that dealt with the supply side of the economy. The six reasons that account for Patinkin’s mistaken interpretation of Keynes’ aggregate supply analysis are the mis-specification of the aggregate supply function, overlooking Pigou’s The Theory of Unemployment, reliance on the unsupported claims of Richard Kahn and Joan Robinson, acceptance of Richard Kahn’s claim that he developed the supply side analysis for Keynes in the General Theory, acceptance of Kahn’s claim that Keynes was a poor mathematician, and acceptance of the false claims of H. Townshend.
