F. A. Hayek's long-overlooked volume, was his most detailed work in economic theory. Originally published in 1941 when fashionable economic thought had shifted to John Maynard Keynes, Hayek's manifesto of capital theory is now available again for today's students and economists to discover. With a new introduction by Hayek expert Lawrence H. White, who firmly situates the book not only in historical and theoretical context but within Hayek's own life and his struggle to complete the manuscript, this edition commemorates the celebrated scholar's last major work in economics. Offering a detailed account of the equilibrium relationships between inputs and outputs in an economy, Hayek's stated objective was to make capital theory useful for the analysis of the monetary phenomena of the real world. His ambitious goal was nothing less than to develop a capital theory that could be fully integrated into the business cycle theory.
