"The all-inclusiveness of the equilibrium concept in New Classicism warns against comparisons of EBCT and ABCT that ignore the radically different methodological contexts.  For instance, the inevitable bust that figures importantly in ABCT cannot easily be translated into the language of EBCT.  For the Austrians, "equilibrium bust" is a term at war with itself; for the New Classicists, "disequilibrium bust" can only mean an unexplainable downturn ."

“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.”

“The recent flourishing of New Classical economics, and especially its Equilibrium Business Cycle Theory , has given a fresh hearing to the Old—but still developing—Austrian Business Cycle Theory .  While the New and the Old differ radically in both substance and methods, they exhibit a certain formal congruency that has captured the attention of both schools.  The formal similarities between EBCT and ABCT invites a point-by-point comparison, but the comparison itself dramatizes differences between the two views in a way that adds to the integrity and plausibility of the Austrian theory.”
