Involuntary unemployment: the missing piece in Keynes's General Theory

Abstract: Using a retrospective methodology, my paper examines critically the insights on involuntary unemployment offered by Keynes in his General Theory. Keynes, it is argued, gave involuntary unemployment a modern micro-founded definition yet — quite opportunely, in view of the difficulty of the task—did not attempt to provide a direct microeconomic explanation of it Rather, his claim to the demonstration of its existence rests on an indirect argument, where involuntary unemployment emerges at the corollary of effective demand falling short of its full employment level. This justification is based on the more or less tacit assumption that involuntary unemployment and effective demand-deficiency are equivalent. This claim of equivalence, it will be argued, is wanting. Hence the view that involuntary unemployment may have been demonstrated through the proxy of demand-deficiency falls. My paper evaluates whether Keynes's other arguments in favour of involuntary unemployment are robust. Several alternative interpretations of his General TheoryChapter Two 'fundamental observation', focusing respectively on money illusion, adjustment flaws, and resistance to cuts in nominal wages, are discussed. Here also the verdict will be negative. The general conclusion then follows that no solid explanation for the existence of involuntary unemployment is to be found in theGeneral Theory.
