J.-C.-L. Simonde de Sismondiwas a Swiss economist and historian who warned against the perils of unchecked industrialism. His pioneering theories on the nature of economic crises and the risks of limitless competition, overproduction, and underconsumption influenced such later economists as Karl Marx and John Maynard Keynes.
Sismondi became a clerk in a bank in Lyon, France, at age 16 and witnessed the unfolding of the French Revolution. To escape the Revolutionâs spreading effects, he and his family went in 1794 to Tuscany, where they became farmers. Sismondiâs experiences and observations there resulted in Tableau de lâagriculture toscane (1801; Picture of Tuscan Agriculture). Living in his native Geneva from 1800 on, he became such a successful author of books and essays that he could decline offers of professorships.
Sismondiâs monumental 16-volume Histoire des rĂ©publiques italiennes du moyen Ăąge (1809â18; History of the Italian Republics in the Middle Ages), which regarded the free cities of medieval Italy as the origin of modern Europe, inspired the leaders of that countryâs Risorgimento (nationalist unification movement).
As an economist, Sismondi was at first a loyal follower of Adam Smith, the proponent of laissez-faire economics. His Nouveaux principes dâĂ©conomie politique (1819; âNew Principles of Political Economyâ), however, represented a break with Smithâs ideas. Sismondi argued for governmental regulation of economic competition and for a balance between production and consumption. He foresaw a growing rift between the bourgeoisie and the working classâcoining the term class struggleâand called for reforms to ameliorate the living conditions of the latter, though he stopped short of condemning private property.
