The Paul Davidson Papers span the years 1961-2004 and document his professional career and interests, including post-Keynesian economics; international monetary payments and global employment policies; monetary theory; income distribution; and energy economics. The collection almost exclusively consists of correspondence files, with the exception of a few clippings and speeches folders. The most notable group of correspondents are his fellow post-Keynesians such as Victoria Chick, Alfred Eichner, John Kenneth Galbraith, Geoff Harcourt, Jan Kregel, Hyman Minsky, Basil Moore, Luigi Pasinetti, Joan Robinson, Anthony Thirlwall, and Sidney Weintraub. Other correspondents of note include Philip Arestis, Peter Bernstein, Robert Clower, Robert Eisner, Sir John Hicks, Allan H. Meltzer, Edward Nell, Don Patinkin, James Tobin, and Paul Samuelson. Other large amounts of correspondence and other materials relate to Davidson's editorial work with many major economics journals, including the , which he founded; these folders typically contain correspondence between Davidson, journal referees, and authors. In one group of folders, Davidson engages with other colleagues in sometimes heated exchanges about bias in professional journals. In addition to correspondence with colleagues and authors, the files also contain correspondence related to academic departments where Davidson held positions. Reflecting his broad background, the papers also document Davidson's involvement with politics (see the Congress folder) and consultancy work for an energy company in his early career (the Oil and Energy folders), and his role as an active public figure, documented by letters to the editor for various maistream publications.
