Competition and Entrepreneurship defines Israel M. Kirzner's unique contribution to the economics profession. Pointing out the shortcomings of the traditional microeconomic model, Kirzner offers an alternative and complementary view, which illuminates and enriches the way economists think of the market process. Recognizing that economics cannot explain sheer novelty and ultimately social change by referring only to productive factors already in use, Kirzner develops a theory of the market process that focuses on the role of the pure entrepreneurial element in human action. This leads him to reconstruct the theory of price in order to understand, as he puts it, "how the decisions of individual participants in the market interact to generate the market forces which compel changes in prices, outputs, and methods of production and in the allocation of resources." In doing so, Kirzner offers a new appraisal of competition moving the entrepreneurial function back to center stage, thereby shedding new light on issues such as monopoly pricing, cartels, and pure profit. No other economist in recent times has been so closely identified with the Austrian School of economics as Kirzner. A leader of the generation of Austrian economists after Ludwig von Mises and F. A. Hayek, Kirzner has been recognized as one of the minds behind the revival of entrepreneurship and market process theory in the twentieth century.

The second volume in Liberty Fund's Collected Works of Israel M. Kirzner series, Market Theory and the Price System was published in 1963 as Kirzner's first (and only) textbook. This volume presents an integrated view of Austrian price theory. The basic aim of Market Theory is to utilize the tools of economic reasoning to explain the market process. The unique framework Kirzner develops for microeconomic analysis, following Mises and Hayek, examines errors in decision-making, entrepreneurial profit, and competition as a process of discovery and learning.
