Accounting for the artificial boom and the consequent bust is not part of Keynesian income-expenditure analysis, nor is it an integral part of monetarist analysis. The absence of any significant relationship between boom and bust is an inevitable result of dealing with the investment sector in aggregate terms. The analytical oversight derives from theoretical formulation in Keynesian analysis and from empirical observation in monetarist analysis. But from an Austrian perspective, the differences in method and substance are outweighed by the common implication of Keynesianism and monetarism, namely, that there is no boom-bust cycle of any macroeconomic significance.
