Produced throughout the first fifteen years of Hayek’s career, the writings collected inCapital and Interestsee Hayek elaborate upon and extend his landmark lectures that were published asPrices and Productionand work toward the technically sophisticated line of thought seen in his laterPure Theory of Capital.Illuminating the development of Hayek’s detailed contributions to capital and interest theory, the collection also sheds light on how Hayek’s work related to other influential economists of the time. Highlights include the 1936 article “The Mythology of Capital”—presented here alongside Frank Knight’s criticisms of the Austrian theory of capital that prompted it—and “The Maintenance of Capital,” with subsequent comments by the English economist A. C. Pigou. These and other familiar works are accompanied by lesser-known articles and lectures, including a lecture on technological progress and excess capacity. An introduction by the book’s editor, leading Hayek scholar Lawrence H. White, places Hayek’s contributions in careful historical context, with ample footnotes and citations for further reading, making this a touchstone addition to the University of Chicago Press’s Collected Works of F. A. Hayek series.
