Question: What prize was won by the American economist whose life story is included in those in Radicals for Capitalism? 

full_context: Document 1: Douglass North: Douglass Cecil North (November 5, 1920 – November 23, 2015) was an American economist known for his work in economic history. He was the co-recipient (with Robert William Fogel) of the 1993 Nobel Memorial Prize in Economic Sciences. In the words of the Nobel Committee, North and Fogel "renewed research in economic history by applying economic theory and quantitative methods in order to explain economic and institutional change."
Document 2: Robert Solow: Robert Merton Solow, GCIH ( ; born August 23, 1924), is an American economist, particularly known for his work on the theory of economic growth that culminated in the exogenous growth model named after him. He is currently Emeritus Institute Professor of Economics at the Massachusetts Institute of Technology, where he has been a professor since 1949. He was awarded the John Bates Clark Medal in 1961, the Nobel Memorial Prize in Economic Sciences in 1987, and the Presidential Medal of Freedom in 2014. Three of his PhD students, George Akerlof, Joseph Stiglitz, and Peter Diamond, later received Nobel Memorial Prizes in Economic Sciences in their own right.
Document 3: Liberalism (book): Liberalism (original German title: "Liberalismus") is an influential book by Austrian School economist and libertarian thinker Ludwig von Mises, containing economic analysis and indicting critique of socialism. It was first published in 1927 by Gustav Fischer Verlag in Jena and defending classical liberal ideology based on individual property rights. Starting from the principle of private property, Mises shows how the other classical liberal freedoms follow from property rights and argues that liberalism free of government intervention is required to promote peace, social harmony and the general welfare. The book was translated into English by a student of Mises, Ralph Raico, but its first English edition in 1962 was titled "The Free and Prosperous Commonwealth" rather than "Liberalism", as Mises thought that the literal translation would create confusion because the term liberalism after the New Deal and especially in the 1960s became widely used in the United States to refer to a centre-left politics that supports degrees of government intervention, in opposition to Mises' central premise. The English translation was made available online by the Ludwig von Mises Institute in 2000.
Document 4: Milton Friedman: Milton Friedman ( ; July 31, 1912 – November 16, 2006) was an American economist who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy. With George Stigler and others, Friedman was among the intellectual leaders of the second generation of Chicago price theory, a methodological movement at the University of Chicago's Department of Economics, Law School, and Graduate School of Business from the 1940s onward. Several students and young professors that were recruited or mentored by Friedman at Chicago went on to become leading economists; they include Gary Becker, Robert Fogel, Thomas Sowell, and Robert Lucas, Jr.

In 1978 Hayek published a revised and enlarged edition entitled Denationalization of Money: The Argument Refined, where he speculated that rather than entertaining an unmanageable number of currencies, markets would converge on one or only a limited number of monetary standards, on which institutions would base the issue of their notes.

Rothbard was the founder and leading theoretician of anarcho-capitalism, a staunch advocate of historical revisionism, and a central figure in the twentieth-century American libertarian movement. He wrote over twenty books on political theory, revisionist history, economics, and other subjects. Rothbard asserted that all services provided by the "monopoly system of the corporate state" could be provided more efficiently by the private sector and wrote that the state is "the organization of robbery systematized and writ large." He called fractional-reserve banking a form of fraud and opposed central banking. He categorically opposed all military, political, and economic interventionism in the affairs of other nations. According to his protégé Hans-Hermann Hoppe, "There would be no anarcho-capitalist movement to speak of without Rothbard."

Document 14: Libertarian utopia: There have been many attempts and proposals to create a libertarian utopia. Anthony van Fossen writes that every tax haven is a variation on the theme of the sovereign libertarian utopia. The Pacific Islands have seen several attempts, such as the Republic of Minerva. Charter cities have been another proposal for breaking out of conventional political arrangements to create a system with much greater scope for innovation in rules. Robert Nozick's book "Anarchy, State and Utopia" contains a final chapter that describes a pluralistic libertarian utopia. Proposals for an anarcho-capitalist society are sometimes regarded as inherently utopian. David Boaz has argued that the consumer choice facilitated by a free market system would create a framework that could offer thousands of versions of utopia to suit the desires of different people.
