A student of Menger's in Vienna and an early disciple of Leon Walras, Henry L. Moore can be rightly considered the only American (and perhaps the only English-speaking) member of the original Lausanne School.
Moore's life-long work was one of the first serious empirical examinations of Marginalist Revolution in general, and Walras's system in particular. He dedicated himself to the statistical derivation of demand curves (a task carried on by his student, Henry Schultz), and the statistical test of J.B. Clark's marginal productivity theory (a task continued by his other student, P.H. Douglas).
He also delved deeply into discovering the connection between commodity business cycles and equilibrium theory - thereby performing one of the earliest empirical examinations of the business cycle in a general equilibrium theory context. His theory of the cycle was "external" - driven by eight-year cycles of rainfall. His magnum opus, Synthetic Economics,(1929) was a herculean attempt to estimate Walras's general equilibrium system.
Although he never was quite successful in his estimation efforts, H.L.Moore and his students at Columbia, notably Schultz and Douglas, accomplished much in pioneering empirical work that would influence later econometricians and business cycle economists such as W.C. Mitchell.
