Samuelson was awarded the [[John Bates Clark Medal]] in [[1947]] and was sole recipient of the [[Nobel Prize in Economics]] in [[1970]], the second year of the Prize.<ref>[http://nobelprize.org/nobel_prizes/economics/laureates/1970/samuelson-lecture.html "Maximum Principles in Analytical Economics"], Nobel Prize Lecture</ref> == Biography == Samuelson was born in [[Gary, Indiana]] on [[May 15]], [[1915]]. His father was a pharmacist and he was brought up in a Jewish family (although they were not practicing).{{Fact|date=June 2008}} In 1923 Paul moved to Chicago. He studied at the [[University of Chicago]] and received his Bachelor of Arts degree in 1935. He then completed his Master of Arts degree in 1936, and his Doctor of Philosophy in 1941 from [[Harvard University]]. As a graduate student at Harvard, Samuelson studied economics under [[Joseph Schumpeter]], [[Wassily Leontief]], [[Gottfried Haberler]], and the "American Keynes" [[Alvin Hansen]]. === Professional positions === * Came to M.I.T. in 1940 as an Assistant Professor of Economics and was appointed Associate Professor in 1944. * Served as a staff member of the Radiation Laboratory from 1944-1945 * Professor of International Economic Relations (part-time) at the [[Fletcher School of Law and Diplomacy]] in 1945. * Professor at M.I.T. in 1947 and now an [[List of Institute Professors|Institute Professor]]. * Guggenheim Fellow from 1948-1949. ==Memberships== * A member of the [[American Academy of Arts and Sciences]] * A fellow of the [[American Philosophical Society]] and the [[British Academy]]; * A member and past President (1961) of the [[American Economic Association]] * A member of the editorial board and past-President (1951) of the [[Econometric Society]] * A fellow, council member and past Vice-President of the [[Economic Society]]. * A member of [[Phi Beta Kappa]]. ==Fields of interest== As professor of economics at the [[Massachusetts Institute of Technology]], Samuelson has worked in many fields including: *[[Welfare economics]], in which he popularised the [[Lindahl-Bowen-Samuelson conditions]] (criteria for deciding whether an action will improve welfare) and demonstrated in 1950 the insufficiency of a national-income index to reveal which of two social options was uniformly outside the other's (feasible) [[social welfare function#Bergson-Samuelson social welfare function|Possibility function]] (''Collected Scientific Papers'', v. 2, ch. 77; Fischer, 1987, p. 236). *[[Public finance]] theory, in which he is particularly known for his work on determining the optimal allocation of resources in the presence of both [[public good]]s and [[private good]]s. *[[International economics]], where he influenced the development of two important international trade models: the [[Balassa-Samuelson effect]], and the [[Heckscher-Ohlin model]] (with the [[Stolper-Samuelson theorem]]). *[[Macroeconomics]], where he devised the [[overlapping generations model]] as a way to analyze economic agents' behavior across multiple periods of time (''Collected Scientific Papers'', v. 1, ch. 21). *[[Consumer theory]], he pioneered the [[Revealed preference|Revealed Preference Theory]], which is a method by which it is possible to discern the best possible option, and thus define consumer's utility functions, by observing the [[consumer behaviour]]. == Publications == Samuelson's book ''[[Foundations of Economic Analysis]]'' (1947, Enlarged ed. 1983), is considered his [[magnum opus]]. It is derived from his doctoral dissertation at [[Harvard University]], and makes use of the [[chemical thermodynamics|classical thermodynamic]] methods of American [[thermodynamicist]] [[Willard Gibbs]].<ref>Liossatos, Panagis, S. (2004). “[http://www.fiu.edu/orgs/economics/wp2004/04-14.pdf Statistical Entropy in General Equilibrium Theory],” (pg. 3). Department of Economics, Florida International University.</ref> The book proposes to: * examine underlying analogies between central features in theoretical and applied economics and * study how ''[[operationalism|operationally meaningful]] theorems'' can be derived with a small number of ''analogous methods'' (p. 3), in order to derive "a general theory of economic theories" (Samuelson, 1983, p. xxvi). The book showed how these goals could be parsimoniously and fruitfully achieved, using the language of the mathematics applied to diverse subfields of economics. The book proposes two general hypotheses as sufficient for its purposes: * ''maximizing behavior'' of ''agents'' (including ''consumers'' as to utility and ''business firms'' as to profit) and * economic ''systems'' (including a market and an economy) in ''stable equilibrium''. In the course of analysis, ''[[comparative statics]]'', (the analysis of changes in equilibrium of the system that result from a parameter change of the system) is formalized and clearly stated. The chapter on [[welfare economics]] "attempt(s) to give a brief but fairly complete survey of the whole field of welfare economics" (Samuelson, 1947, p. 252). It also exposits on and develops what became commonly called the [[Abram Bergson|Bergson]]-Samuelson [[social welfare function#Bergson-Samuelson social welfare function|social welfare function]]. It shows how to represent (in the maximization calculus) all real-valued economic measures of any belief system that is required to rank consistently different feasible social configurations in an ethical sense as "better than," "worse than," or "indifferent to" each other (p. 221). There are 388 papers to date in Samuelson's ''Collected Scientific Papers''. [[Stanley Fischer]] (1987, p. 234) writes that taken together they are unique in their verve, breadth of economic and general knowledge, mastery of setting, and generosity of allusions to predecessors. Samuelson is also author (and since 1985 co-author) of an influential principles textbook, ''[[Economics (textbook)|Economics]]'', first published in [[1948]], now in its 18th edition.<ref>{{cite web |url=http://adbusters.org/the_magazine/69/The_Revolution_Will_Begin_with_a_Textbook_Part_One.html |title=Adbusters : The Magazine - #69 The Big Ideas of 2007 / The Revolution Will Begin with a Textbook (Part One) |accessdate=2007-06-29 |format= |work=}}</ref> The book has been translated into forty-one languages and sold over four million copies. He is editor of ''Inside the Economist's Mind: Conversations with Eminent Economists'' (Blackwell Publishing, 2007), along with William A. Barnett, a collection of candid interviews with top economists of the 20th century. == Impact == Along with [[Kenneth Arrow]], Samuelson is considered one of the founders of [[neoclassical economics|modern neoclassical economics]]. The following is an excerpt on the reasons for awarding him the [[Nobel Prize]]: :More than any other contemporary economist, Samuelson has helped to raise the general analytical and methodological level in economic science. He has simply rewritten considerable parts of economic theory. He has also shown the fundamental unity of both the problems and analytical techniques in economics, partly by a systematic application of the methodology of maximization for a broad set of problems. This means that Samuelson's contributions range over a large number of different fields. He was also essential to creating the Neoclassical synthesis, which incorporates [[Keynesian economics|Keynesian]] principles with [[neoclassical economics|neoclassical]] principles and dominates current [[mainstream economics]]. In 2003, Samuelson was one of the 10 Nobel Prize winning economists signing the [[Economists' statement opposing the Bush tax cuts]].<ref name="Econ statement">{{cite web|url=http://www.epinet.org/stmt/2003/statement_signed.pdf|title=Economists' statement opposing the Bush tax cuts|accessdate=2007-10-31}}</ref> ==Thermodynamics and economics== Samuelson was one of the first economists to generalize and apply mathematical methods developed for the study of [[thermodynamics]] to [[economics]]. As a graduate student at [[Harvard]], he was the sole protegé of the polymath [[Edwin Bidwell Wilson]], who had himself been the sole protegé of Yale's great physicist [[Willard Gibbs]].<ref>[http://nobelprize.org/nobel_prizes/economics/articles/samuelson-2/index.html How I Became an Economist] by [[Paul A.

Department of Economics, Florida International University.</ref> In 1947, based on the [[Le Chatelier principle]] of thermodynamics, a principle taught to Samuelson by Wilson in lecture, he established the method of comparative statics in economics. This method explains the changes in the equilibrium solution of a constrained maximization problem (economic or thermodynamic) when one of the constraints is marginally tightened or relaxed. The Le Chatelier principle was developed by French chemist [[Henri Louis le Chatelier]], who is notable for being one of the first to translate Gibbs’ equilibrium papers (in French, 1899). Samuelson’s use of the Le Chatelier principle has proven to be a very powerful tool and found widespread use in modern economics. <ref name="Baumarter" >Baumgarter, Stefan. (2004).

Several years later, Samuelson responded with [[David Ricardo]]'s theory of [[comparative advantage]].<br /> For many years, Samuelson wrote a column for ''[[Newsweek]]''. One article included Samuelson's most quoted remark, and a favorite economics joke: <blockquote> To prove that Wall Street is an early omen of movements still to come in GNP, commentators quote economic studies alleging that market downturns predicted four out of the last five recessions. That is an understatement. Wall Street indexes predicted nine out of the last five recessions! And its mistakes were beauties.<ref>"Science and Stocks," ''Newsweek'', September 1966</ref></blockquote> ==List of publications== * ''[[Foundations of Economic Analysis]]'', Harvard University Press (1947, Enlarged ed. 1983) *''[[Economics (textbook)|Economics: An Introductory Analysis]]'' (1948) McGraw-Hill, ISBN 0-07-074741-5 ; with [[William Nordhaus|William D.
