Título: Irving Fisher
Seção: Utility theory
Background: Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.

Conteúdo: James Tobin argued that the intellectual breakthroughs that marked the neoclassical revolution in economics occurred in Europe around 1870. The next two decades witnessed lively debates, which led to the new theory being more or less incorporated into the classical tradition that preceded it. In the 1890s, according to Joseph A. Schumpeter there emerged  A large expanse of common ground and ... a feeling of repose, both of which created, in the superficial observer, an impression of finality - the finality of a Greek temple that spreads its perfect lines against a cloudless sky. Of course, Tobin argues, the temple was by no means complete. Its building and decoration continue to this day, even while its faithful throngs worship within. American economists were not present at the creation. To a considerable extent they built their own edifice independently, designing some new architecture in the process. They participated actively in the international controversies and syntheses of the period 1870-1914. At least two Americans were prominent builders of the "temple," John Bates Clark and Irving Fisher. They and others brought neoclassical theory into American journals, classrooms, and textbooks, and its analytical tools into the kits of researchers and practitioners. Eventually, for better or worse, their paradigm would dominate economic science in this country.  In reviewing the history of utility theory, economist George Stigler wrote that Fisher's doctoral thesis had been "b
