(1859 - 1924), Italian soldier, politician, and economist with strong mathematical training.
Enrico Barone was a contemporary and interlocutor of both Leon Walras and Vilfredo Pareto, best known for his careful formulation of the equilibrium system that would have to be solved by central planners in a socialist economy. Published in 1908 as "Il Ministro della Produzione nello Stato Collettivista" in the journal Giornale delgi Economisti, and reprinted in English in F. A. Hayek's edited volume, Collectivist Economic Planning, his formulation provided an analytic foundation for arguments supporting the feasibility of socialist calculation, socialist central planning, and ultimately "market socialism." In it he provided a Walrasian (general equilibrium) system of equations whose solutions would resolve the valuation and coordination quandary for socialist central planners - a system of economic rationality without markets for production inputs and capital. Socialist economists such as Oscar Lange, Fred Taylor, and Maurice Dobb, have taken this as a refutation of Ludwig von Mises's critique of the possibility of economic rationality under socialist planning. In particular, it is argued that his formulation shows how modern high-speed multiprocessor computing can be used to find optimal scarcity valuations and prices for all products and assets in an economy, thereby allowing rational formulation of an economic plan by social planners.
Barone also contributed to general equilibrium theory by showing Walras how to incorporate variable production techniques into his equilibrium system of equations (the Walrasian system). This contributed to the development of marginal productivity theory, a central part of neoclassical economic analysis. Finally, he made notable contribution to the economics of taxation in his three studies of public finance in 1912.
