Essays on capital and interest : an Austrian perspective In Essays on Capital and Interest Israel Kirzner offers a consistently Austrian perspective on the problems of capital and interest theory. In the three classic essays featured in this book Professor Kirzner argues that an Austrian approach based on the pure time preference theory offers an attractive alternative to both the orthodox neoclassical and the heterodox Sraffian approaches to economics. The author takes a subjectivist point of view with all capital and interest phenomena traced to individual multi period plans. Capital is seen in this perspective not as an objective mass of tools and equipment but as the interim state in which inter locking multi period plans have manifested themselves at a particular point. This consistent subjectivism makes it possible to present the pure time (Fetter Mises) preference theory of interest in understandable terms. Essays on Capital and Interest begins with an introduction by the author placing his lifes work in the context of twentieth century economics and the decline and revival of the Austrian school. This volume makes Professor Kirzners seminal work available to a wider audience in a major new edition. It will be welcomed by Austrian economists and all those concerned with capital and interest theory
