Career Inspired by Smith's Wealth of Nations, he wrote his Treatise... which introduced Smithian ideas to France and other European countries. His analysis developed beyond Smith's, including an emphasis on the role of the entrepreneur. The famous law of markets (Say's law) became widely accepted of market forces to produce equilibrium of production and demand. His influence dominated officially-taught economics in France for most of the nineteenth century: unorthodox views and different approaches tended to be kept outside the conventionalacademic world and were confined to such institutions as the écoles which trained engineers.
