Leonid Hurwicz (1917-2008) was a Nobel Price winnter and Regents' Professor Emeritus of Economics at the University of Minnesota. This collection primarily documents his professional life through his correspondence, writings, research, and professional and faculty activities. It forms part of the Economists' Papers Archive.

The materials in this collection are from Hurwicz's office at the University of Minnesota and his home.

The primary subjects are econometrics, the stability of general equilibrium, the integrability of demand functions, decision-making under uncertainty, welfare economics, game theory and incentive theory, and the development of mechanism design. Hurwicz contributed many papers in these fields, and there are also files that show his interest in the transition toward market economies in China, Russia, and Eastern European countries during the 1980s-1990s.

The most common types of material are manuscript files for writings, research files, and correspondence files. There is a small set of annotated books, plus 18 floppy discs, one CD, two DVDs, and one email account, the contents of which have all been transferred to a server and are available. The CD contains three backups of Hurwicz's computer with correspondence, writings, research, and teaching material.

The bulk of the collection is in the Writings series and the Research and Notes series, which contain many collaborations and exchanges with other economists, most prominently Kenneth Arrow, Thomas Marschak, Roy Radner, Stanley Reiter, Marcel Richter, Donald Saari, and Hirofumi Uzawa. Hurwicz knew and corresponded with many other economists, mainly those working in the fields of mathematical economics, welfare economics, and institutional economics. He annotated many of the working papers that were sent to him throughout his life by other economists, such as Theodore Bergstrom, Jerry Green, Philip Hartman, Eric Maskin, William Thompson, and Jan Werner.

In addition to Hurwicz's writings and research, the collection also follows his professional activities as a teacher and faculty member at the University of Minnesota in the Economics Department. There is correspondence with colleagues such as John Chipman and Vernon Ruttan and with former students such as Tatsuyoshi Saijo, as well as meeting minutes and committee material. A number of files concern his work with outside groups such as the Cowles Commission, the RAND Corporation, the National Science Foundation, the National Academy of Sciences, and the American Academy of Arts and Sciences. Finally, some files document his presentations at seminars, workshops, and conferences, as well as his other travels to invited lectures, award ceremonies, and other presentations.

Through correspondence, research notes, article drafts, teaching material, lectures, and published materials, this collection provides a broad overview of McKenzie's professional career. His greatest contribution to economics was his work in conjunction with Kenneth Arrow and Gerard Debreu on general equilibrium, and his writings on capital theory and turnpike theory, all of which are documented in a variety of forms throughout the collection. Significant correspondents include noted economists Paul Samuelson, Tjalling Koopmans, and Robert Solow. Other aspects of his career are documented, such as his involvement in a number of economic organizations, especially the Econometric Society and the Mathematical Social Sciences Board; his role as organizer of a number of academic conferences, such as the Value and Capital Conference of 1988; and his teaching career at Duke University from 1948-1957 and the University of Rochester from 1957-1989.

The Correspondence series, the largest of the collection, contains largely official and routine correspondence, but also includes a sizeable number of letters on intellectual topics.

The Research and Writings series, the second largest, has various drafts and iterations of most of McKenzie's published work as well as some unpublished material. Many of the notes contain complicated mathematical notations documenting the theoretical foundations for his work. A small set of writings by others, chiefly on game theory and convex sets, conclude the series.

The Teaching series houses syllabi and other materials from the seminars he taught, including many versions of the handwritten text for his general equilibrium seminar, documenting his teaching methods as well as the evolution in his thinking on the subject.
