Paul Samuelson

Paul Samuelson is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Paul Samuelson rather than just read about it. In short: Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist who was the first American to win the Nobel Memorial Prize in Economic Sciences. When awarding the prize in 1970, the Swedish Royal Academies stated that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory".

Key takeaways

  • Paul Samuelson belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Paul Samuelson to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Paul Samuelson from memory before moving on to harder problems.

Reference excerpt

Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist who was the first American to win the Nobel Memorial Prize in Economic Sciences. When awarding the prize in 1970, the Swedish Royal Academies stated that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Samuelson was one of the most influential economists of the latter half of the 20th century. In 1996, he was awarded the National Medal of Science. Samuelson considered mathematics to be the "natural language" for economists and contributed significantly to the mathematical foundations of economics with his book Foundations of Economic Analysis. He was author of the best-selling economics textbook of all time: Economics: An Introductory Analysis, first published in 1948. It was the second American textbook that attempted to explain the principles of Keynesian economics. Samuelson served as an advisor to President John F. Kennedy and President Lyndon B. Johnson, and was a consultant to the United States Treasury, the Bureau of the Budget and the President's Council of Economic Advisers. Samuelson wrote a weekly column for Newsweek magazine along with Chicago School economist Milton Friedman, where they represented opposing sides: Samuelson, as a self described "Cafeteria Keynesian", claimed taking the Keynesian perspective but only accepting what he felt was good in it. By contrast, Friedman represented the monetarist perspective. Together with Henry Wallich, their 1967 columns earned the magazine a Gerald Loeb Special Award in 1968.

Biography

Samuelson was born in Gary, Indiana, on May 15, 1915, to Frank Samuelson, a pharmacist, and Ella née Lipton. His family, he later said, was "made up of upwardly mobile Jewish immigrants from Poland who had prospered considerably in World War I, because Gary was a brand new steel-town when my family went there". In 1923, Samuelson moved to Chicago where he graduated from Hyde Park High School (now Hyde Park Career Academy). Samuelson attended the University of Chicago as an undergraduate, earning a Bachelor of Arts degree in 1935. He said he was born as an economist at 8:00 am on January 2, 1932, in the University of Chicago classroom. The lecture mentioned as the cause was on the British economist Thomas Malthus, who most famously studied population growth and its effects. Samuelson felt there was a dissonance between neoclassical economics and the way the system seemed to behave; he said Henry Simons and Frank Knight were a big influence on him. He next completed his Master of Arts degree in 1936, and his Doctor of Philosophy in 1941 at Harvard University. He won the David A. Wells Prize in 1941 for writing the best doctoral dissertation at Harvard University in economics, for a thesis titled "Foundations of Analytical Economics", which later turned into Foundations of Economic Analysis. As a graduate student at Harvard, Samuelson studied economics under Joseph Schumpeter, Wassily Leontief, Gottfried Haberler, and the "American Keynes" Alvin Hansen. Samuelson moved to MIT as an assistant professor in 1940 and remained there until his death. Samuelson's biographer argues that a central reason for Samuelson's move from Harvard to MIT was the anti-Semitism that was famously widespread at Harvard at the time. In a 1989 letter to his friend Henry Rosovsky, Samuelson blamed anti-Semitism in Harvard economics above all on chair Harold Burbank, as well as on Edward Chamberlin, John H. Williams, John D. Black, and Leonard Crum. Samuelson's family included many well-known economists, including brother Robert Summers, sister-in-law Anita Summers, brother-in-law Kenneth Arrow and nephew Larry Summers. During his seven decades as an economist, Samuelson's professional positions included:

Assistant professor of economics at MIT, 1940; associate professor, 1944. Member of the Radiation Laboratory 1944–45. Professor of international economic relations (part-time) at the Fletcher School of Law and Diplomacy in 1945. Guggenheim Fellowship from 1948 to 1949 Professor of economics at MIT beginning in 1947 and Institute Professor beginning in 1962. Vernon F. Taylor Visiting Distinguished Professor at Trinity University (Texas) in spring 1989.

Death Samuelson died after a brief illness on December 13, 2009, at the age of 94. His death was announced by the Massachusetts Institute of Technology. James M. Poterba, an economics professor at MIT and the president of the National Bureau of Economic Research, commented that Samuelson "leaves an immense legacy, as a researcher and a teacher, as one of the giants on whose shoulders every contemporary economist stands". Susan Hockfield, the president of MIT, said that Samuelson "transformed everything he touched: the theoretical foundations of his field, the way economics was taught around the world, the ethos and stature of his department, the investment practices of MIT, and the lives of his colleagues and students". His second wife died in 2019.

Worked examples

Example 1 — a first encounter with Paul Samuelson

Start with the simplest possible case. Write down what Paul Samuelson claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Paul Samuelson before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Paul Samuelson ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Paul Samuelson

In research
Paul Samuelson appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Paul Samuelson in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Paul Samuelson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1915 births, 2009 deaths, 20th-century American Jews, so understanding it makes those chapters shorter.
In everyday life
Look for Paul Samuelson outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
