Eugen Slutsky
Evgeny "Eugen" Evgenievich Slutsky (; – 10 March 1948) was a Russian and Soviet mathematical statistician, economist and political economist. Work in economics Slutsky is principally known for work in deriving the relationships embodied in the very well known Slutsky equation which is widely used in microeconomic consumer theory for separating the substitution effect and the income effect of a price change on the total quantity of a good demanded following a price change in that good, or in a related good that may have a cross-price effect on the original good quantity. There are many Slutsky analogs in producer theory. He is less well known by Western economists than some of his contemporaries, due to his own changing intellectual interests as well as external factors forced upon him after the Bolshevik Revolution in 1917. His seminal paper in Economics, and some argue his last paper in Economics rather than probability theory, was published in 1915 (Sulla teoria del bilancio del consumatore). Paul Samuelson noted that until 1936, he had been entirely unaware of Slutsky's 1915 "masterpiece" due to World War I and the paper's Italian language publication. R. G. D. Allen did the most to propagate Slutsky's work on
