Everything about Enrico Barone totally explained
Enrico Barone (b.
December 22,
1859,
Naples,
Italy, d.
May 14,
1924,
Rome) was a soldier, military historian, and economist.
Barone studied the classics and mathematics before becoming an army officer. He taught military history for eight years from 1894 at the Officers' Training School. There he wrote a series of influential historical military works. In these he employed a method of successive approximations to which his study in economics had introduced him. In 1902, he became head of the historical office of the General Staff. He resigned his commission in 1906.
From 1894 he collaborated with
Maffeo Pantaleoni and
Vilfredo Pareto on the
Giornale degli Economisti.
Barone's accomplishments as an economist included these. He was the first to state conditions for which a
competitive market could be
Pareto efficient. He expanded on Pareto efficiency, deducing that not all losers could be compensated for deviations from conditions of competitive equilibrium. He introduced variable factor proportions into
neoclassical economics, contributing to the marginal-productiviy theory of factor-income
distribution. He extended conditions of
general equilibrium in
Walrasian theory, suggesting the feasibility of trial-and-error movement to market equilibrium. He pioneered the economic theory of
index numbers. All this was without use of utility or even
indifference curves.
Barone has been described as a "founder of the pure theory of a socialist economy." In 1908, he presented a mathematical model for a collectivist economy under which certain relations, later identified with
shadow prices, must be satisfied for "maximum collective welfare." The latter corresponds to least-cost-price of production from Pareto efficiency reached in competitive equilibrium. He stressed that such a resuit couldn't be arrived at
a priori but only by experimentation on a large scale with great demands on data collection, even assuming fixity of production relations. In this, he suggested that movement toward economic efficiency in a collectivist economy wasn't inconceivable. For such a regime, whatever the
distribution rule for output and income adopted by the Ministry of Production, the same economic categories would reappear for prices, salaries, interest, rent, profits, saving, etc., though perhaps with different names. His analysis fueled discussion of the
economic calculation problem and
market socialism in the 1930s. His method also anticipated
Abram Bergson's seminal formulation of a
social welfare function three decades later.
