Outros nomes: Пол Самуэльсон

Paul Anthony Samuelson foi um economista americano da escola neokeynesianista.

É considerado um economista "generalista", no sentido de que suas contribuições para a ciência econômica são aplicadas em vários campos.

Tal é explícito na justificação dada pela atribuição do Prémio de Ciências Económicas em Memória de Alfred Nobel em 1970: "pelo trabalho científico através do qual desenvolveu teoria nos campos da economia estática e dinâmica, contribuindo activamente para aumentar o nível da análise da ciência económica". Samuelson foi o primeiro estado-unidense a receber o mais honroso galardão desta ciência social.

Representou e defendeu a doutrina keynesiana, fazendo parte de um grupo de pensadores notáveis como James Tobin e Robert Solow.

Finalmente, pode-se dizer que a partir de Samuelson passou a existir não somente a Economia, como também o livro Economics . O livro Economics ensinou os fundamentos desta ciência à maioria dos estudantes de economia da segunda metade do século XX, fazendo parte dos grandes manuais de Economia juntamente com os livros de Adam Smith , de John Stuart Mill e Alfred Marshall .Foi professor no Instituto de Tecnologia de Massachusetts.

Em 1947, Paul A. Samuelson publicou Fundamentos de Análise Económica que foi objeto de edição alargada em 1983. Kenneth Arrow descreve esta obra como "o único exemplo que conheço de uma tese de doutoramento que é um tratado, talvez deva dizer de um tratado que tem tanta originalidade em cada uma das suas partes que tem o direito de ser aceite como uma tese".Recebeu o Doutoramento Honoris Causa pela Universidade Nova de Lisboa em 1984/1985.

Citações Paul A. Samuelson

„I can claim that in talking about modern economics I am talking about me. My finger has been in every pie.“

—  Paul A. Samuelson
1980s–1990s, Context: I can claim that in talking about modern economics I am talking about me. My finger has been in every pie. I once claimed to be the last generalist in economics, writing about and teaching such diverse subjects as international trade and econometrics, economic theory and business cycles, demography and labor economics, finance and monopolistic competition, history of doctrines and locational economics. February 1985, in William Breit and Roger W. Spencer (ed.) Lives of the laureates

„There is really nothing more pathetic than to have an economist or a retired engineer try to force analogies between the concepts of physics and the concepts of economics.“

—  Paul A. Samuelson
1950s–1970s, Maximum Principles in Analytical Economics, 1970, Context: There is really nothing more pathetic than to have an economist or a retired engineer try to force analogies between the concepts of physics and the concepts of economics. How many dreary papers have I had to referee in which the author is looking for something that corresponds to entropy or to one or another form of energy. Nonsensical laws, such as the law of conservation of purchasing power, represent spurious social science imitations of the important physical law of the conservation of energy; and when an economist makes reference to a Heisenberg Principle of indeterminacy in the social world, at best this must be regarded as a figure of speech or a play on words, rather than a valid application of the relations of quantum mechanics. p. 69

„Good questions outrank easy answers.“

—  Paul A. Samuelson
1980s–1990s, Context: The recent market run-up that appreciated run-of-the- mill shares also chanced to send up those token gold holdings. Pure luck, undeserved and unlikely to reoccur. Good questions outrank easy answers. In: Paul Anthony Samuelson, ‎Kate Crowley (1986), The Collected Scientific Papers, Volume 5, p. 561

„In the preface to the reissue of Risk, Uncertainty and Profit, Frank Knight makes the penetrating observation that under the conditions envisaged above the velocity of circulation would become infinite and so would the price level. This is perhaps an over-dramatic way of saying that nobody would hold money, and it would become a free good to go into the category of shell and other things which once served as money. We should expect too that it would not only pass out of circulation, but it would cease to be used as a conventional numeraire in terms of which prices are expressed. Interest bearing money would emerge. Of course, the above does not happen in real life, precisely because uncertainty, contingency needs, non-synchronization of revenues and outlay, transaction frictions, etc., etc., all are with us. But the abstract special case analyzed above should warn us against the facile assumption that the average levels of the structure of interest rates are determined solely or primarily by these differential factors. At times they are primary, and at other times, such as the twenties in this country, they may not be. As a generalization I should hazard the hypothesis that they are likely to be of great importance in an economy in which there is a “quasi-zero" rate of interest. I think by this hypothesis one can explain many of the anomalies of the United States money market in the thirties.“
