Biography

Samuelson was born in Gary, Indiana on May 15, 1915. His father was a pharmacist and he was brought up in a practicing Jewish family. 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.

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) 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 goods and private goods.
• 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 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 classical thermodynamic methods of American thermodynamicist Willard Gibbs.Liossatos, Panagis, S. (2004). “Statistical Entropy in General Equilibrium Theory,” (pg. 3). Department of Economics, Florida International University. The book proposes to:

• examine underlying analogies between central features in theoretical and applied economics and
• study how 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 Bergson-Samuelson 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, first published in 1948, now in its 18th edition.Adbusters : The Magazine - #69 The Big Ideas of 2007 / The Revolution Will Begin with a Textbook (Part One). Retrieved on 2007-06-29. 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 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 principles with 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.Economists\' statement opposing the Bush tax cuts.

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.How I Became an Economist by Paul A. Samuelson, 1970 Laureate in Economics, 5 September 2003 Gibbs, the founder of chemical thermodynamics, was also mentor to American economist Irving Fisher and he influenced them both in their ideas on the equilibrium of economic systems.Eric Smith, Duncan Foley (2005), Classical Thermodynamics and Economic General Equilibrium TheoryMirowski, Philip (1989). More Heat than Light: Economics as Social Physics, Physics as Nature\'s Economics. Cambridge Univ. Press. ISBN 0521426898. 

Samuelson’s 1947 magnum opus Foundations of Economic Analysis, from his doctoral dissertation, is based on the classical thermodynamic methods of American thermodynamicist Willard Gibbs, specifically Gibbs\' 1876 paper On the Equilibrium of Heterogeneous Substances. P A Samuelson, Gibbs in economics, Proceedings of the Gibbs Symposium (Providence, R.I., 1990), 255-267.K R Jolls, Gibbs and the art of thermodynamics, Gibbs in economics, Proceedings of the Gibbs Symposium (Providence, R.I., 1990), 293-321.Liossatos, Panagis, S. (2004). “Statistical Entropy in General Equilibrium Theory,” (pg. 3). Department of Economics, Florida International University.

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. Baumgarter, Stefan. (2004). Thermodynamic Models, Modeling in Ecological Economics (Ch. 18) Attempts at neo-classical equilibrium economics analogies with thermodynamics generally, go back to Guillaume and Samuelson. McCauley Joseph. l. (2004). “Thermodynamic analogies in economics and finance: instability of markets” Published in: Physica A.329 (2003): pp. 199-212.

Criticism

According to Canadian economist Tom Green, Samuelson erroneously assumes that people continuously act in a rational manner, omitting the effects of culture, advertisement and other influences on human decision making. He writes:Green, T. (2007). The Revolution Will Begin with a Textbook. Adbusters Magazine.. Retrieved on 2007-10-31.

“

Samuelson admits that utility is a construct that has no basis in psychology; although he uses the terms ‘consumer’ and ‘individual,’ his model is built around a fictional character that critics have dubbed Homo economicus. This economic man (yes, he is male) never had a childhood, never has children, has never depended upon a caregiver and does not have anyone he provides care for. He only experiences well-being by consuming. He is rational, selfish, a psychopath... he isn’t influenced by hundreds of billions of dollars in advertising or the purchases of his neighbors. If Homo economicus buys something, it gives him utility; his consumer sovereignty must be respected.

”

Miscellaneous

Stanislaw Ulam once challenged Samuelson to name one theory in all of the social sciences which is both true and nontrivial. Several years later, Samuelson responded with David Ricardo\'s theory of comparative advantage.
