When Murray Rothbard laid eyes on this classic monograph, he cheered. Here we have a graphical presentation that explains the Austrian view of macroeconomics in contrast to the simple and even simple-minded approach of the Keynesian aggregates.The value here is to highlight the distinct emphasis of the Austrian School: time matters, capital is heterogeneous, interest is not arbitrary, investment reflects human volition, and production plans adapt to prevailing prices.
