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. 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 19th edition. The book has been translated into forty-one languages and sold over four million copies; it is considered the best-selling economics textbook in history. Written in the shadow of the Great Depression and World War II, it helped to popularize the insights of John Maynard Keynes. A main focus was how to avoid, or at least mitigate, the recurring slumps in economic activity. Samuelson wrote: "It is not too much to say that the widespread creation of dictatorships and the resulting World War II stemmed in no small measure from the world's failure to meet this basic economic problem adequately." This reflected the concern of Keynes himself with the economic causes of war and the importance of economic policy in promoting peace. Samuelson's influential textbook has been criticized for including comparative growth rates between the United States and the Soviet Union that were inconsistent with historical GNP differences. The 1967 edition extrapolates the possibility of Soviet/U.S. real GNP parity between 1977 and 1995. Each subsequent edition extrapolated a date range further in the future until those graphs were dropped from the 1985 edition. Samuelson concluded the economic description of the Soviet Union and marxism in 1989: "Contrary to what many skeptics had earlier believed, the Soviet economy is proof that … a socialist command economy can function and even thrive." The Collapse of Communism happened during the same year and the Soviet Union broke up two years later.

Samuelson is co-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.
