The Optimum Quantity of Money

by Milton Friedman, Michael Bordo (Introduction)

This classic set of essays by Nobel Laureate and leading monetary theorist Milton Friedman presents a coherent view of the role of money, focusing on specific topics related to the empirical analysis of monetary phenomena and policy. The early chapters cover factors determining the real quantity of money held in a community and the welfare implications of policies that affect the quantity held. The following chapters formally restate why quantity analysis has become central to the science of economics. Friedman's presidential address to the American Economic Association, included here, provides a general summary of his views on the role of monetary policy, with an emphasis on its limitations and its possibilities. This theoretical framework is used in examining a number of empirical the demand for money, the explanation of price changes in wartime periods, and the role of money in business cycles. These essays summarize some of the most important results of Friedman's extensive research over the course of his lifetime. The chapters on policy that follow survey the positions of earlier economists and deal with the importance of lags and the implications of destabilizing speculation in foreign markets. Taken as a whole, The Optimum Quantity of Money provides a comprehensive view of the body of monetary theory developed in leading centers of monetary analysis. This work is essential reading for economists and graduate students in the field. The volume will be no less important for practicing business and banking personnel as well. The new statement by Michael Bordo, a student of Friedman's and an expert in the field, provides a sense of where the field now stands in the economy and academy.

About the author

Milton Friedman was an American economist who became one of the most influential and controversial figures of the twentieth century, widely recognized for his profound contributions to monetary economics, consumption theory, and the defense of classical liberalism. A leading figure of the Chicago School of Economics, Friedman challenged the prevailing Keynesian consensus that dominated mid-century policy and instead placed monetary policy at the center of economic stability, arguing that changes in the money supply were the primary drivers of inflation and fluctuations in output. His groundbreaking permanent income hypothesis reshaped the study of consumer behavior by suggesting that individuals make spending decisions based on long-term expected income rather than current earnings, a theory that profoundly influenced both academic research and practical policymaking. Alongside Anna Schwartz, Friedman coauthored A Monetary History of the United States, 1867–1960, a monumental work that emphasized the role of Federal Reserve mismanagement in deepening the Great Depression, a thesis that redefined historical understanding of the period and helped establish monetarism as a major school of thought. His broader philosophy was articulated in works such as Capitalism and Freedom, where he argued that political and economic liberty are interdependent and advanced ideas like educational vouchers, voluntary military service, deregulation, floating exchange rates, and the negative income tax, each reflecting his conviction that society functions best when individuals are free to choose. Together with his wife Rose Friedman, he later brought these ideas to a global audience through the bestselling book and television series Free to Choose, which made complex economic principles accessible to millions and expanded his influence beyond academia. Awarded the Nobel Prize in Economic Sciences in 1976 for his achievements in consumption analysis, monetary history, and stabilization policy, Friedman became a prominent public intellectual, sought after by policymakers and leaders around the world. His ideas strongly influenced U.S. policy in the late twentieth century, particularly during the administration of Ronald Reagan, and found resonance in the economic reforms of Margaret Thatcher in the United Kingdom, both of whom embraced aspects of his prescriptions for free markets and limited government intervention. Friedman’s policy recommendations consistently opposed measures he regarded as distortions of market efficiency, including rent control, agricultural subsidies, and occupational licensing, while he proposed alternatives such as direct cash transfers through a negative income tax to replace complex welfare bureaucracies. His teaching career at the University of Chicago shaped generations of economists, many of whom extended his research and helped institutionalize the Chicago School as a major force in global economic thought, while his later role at the Hoover Institution at Stanford University provided him with a platform to continue his scholarship and public advocacy. Beyond technical economics, Friedman’s clarity of expression and ability to frame debates in terms of individual freedom versus state control made him one of the most recognizable intellectuals of his era, admired by supporters for his defense of personal liberty and market efficiency, and criticized by detractors who accused him of underestimating inequality, social costs, and the complexities of government responsibility. Despite the controversies, his impact on the development of modern economics was immense, reshaping debates about inflation, unemployment, fiscal policy, and the role of the central bank. His writings, lectures, and media appearances consistently reinforced his belief that competitive markets, voluntary exchange, and limited government intervention offer the most effective means of promoting prosperit
