LARGE PRINT EDITION! More at LargePrintLiberty.com These seven works taken together represent the first integration and systematic elaboration of the Austrian theories of money, capital, business cycles, and comparative monetary institutions, which constitute the essential core of Austrian macroeconomics. These works have profoundly influenced postwar expositions of Austrian or capital-based macroeconomics down to the present day. The creation of such an oeuvre is a formidable intellectual feat over an entire lifetime; it is an absolute marvel when we consider that Hayek had completed it in the span of eight years (1929–1937) and still well shy of his fortieth birthday. Hayek’s amazingly precocious intellect and creative genius are on full display in these works.
