From the Analytical Viewpoint of the Austrian School, Monetarists and Keynesians Use Very Similar Approaches and Methodologies

We must emphasize that from the analytical viewpoint we adopt in our book, i.e., that of the Austrian School, monetarists and Keynesians use very similar approaches and methodologies. Like monetarists, Keynes held no capital theory to enable him to understand the division of economic processes into productive stages and the role time plays in such processes. Furthermore his macroeconomic theory of prices rests on such concepts as the general price level, the overall amount of money in circulation, and even the velocity of circulation of money. Nevertheless certain significant peculiarities of Keynesian thought warrant discussion.
