Leonid Hurwicz (1917-2008) was a major figure in modern theoretical economics whose contributions over sixty-five years spanned at least five areas: econometrics, nonlinear programming, decision theory, microeconomic theory, and mechanism design. While some of Hurwicz's work were published in journals, many remain scattered as chapters in books which are difficult to access and others were never published at all. The Collected Papers of Leonid Hurwicz is the first volume in a series of four that will bring his oeuvre in one place, to bring to light the totality of his intellectual output, and to document his contribution to economics and the extent of his legacy, with the express purpose to make it easily available for future generations of researchers to build upon.
