After Ludwig von Mises's death in 1973, his wife, Margit von Mises, went through his unpublished and out-of-print essays and selected twenty-one of the essays for publication. The result was Money, Method, and the Market Process, published in 1990 by Kluwer Academic Publishers and the Ludwig von Mises Institute and reissued now by Liberty Fund. In his introduction to the book, Richard Ebeling describes it as a "convenient composite of Misesian economics.'" He says that the essays here touch on "almost every aspect of economic and social theory that Mises considered of paramount importance. The essays were written over a period of forty years, from the 1930s to the 1960s, so they serve as a wide sampling of Mises's thought on a wide range of subjects, and they are arranged thematically. The three essays in the first section, on "Method," discuss the differences between the social and natural sciences and include some of Mises's thoughts on the science of human action. The essays in the next section, on "Money," discuss inflation and money in economic exchange, and they include Mises's analysis of why stabilizing the price level will not necessarily stabilize economic activity. This leads readers to the section on "Trade," where Mises warns of the danger of international conflict in a world without free trade.There are seven essays on "Comparative Economic Systems," and they include detailed studies on capitalism versus socialism, the cooperative movement, the Russian Reform Movement, and equality and inequality. Under the heading of "Ideas," the final two essays are "The Role of Doctrines in Human History" and the well-known piece called "The Idea of Liberty Is Western".
