Jean-Baptiste Say (1767-1832) was a French economist and businessman. He had classically liberal views and argued in favour of competition, free trade and lifting restraints on business. He originated Say's law, which is often quoted incorrectly as "supply creates its own demand". His first literary attempt was a pamphlet on the liberty of the press, published in 1789. From 1794 to 1800 Say edited a periodical entitled La Decade Philosophique, Litteraire, et Politique, in which he expounded the doctrines of Adam Smith. In 1800 he published in Olbie; ou, Essai sur les Moyens de Reformer les Moeurs d'une Nation. In 1803 appeared his principal work, the Traite d'Economie Politique; ou, Simple Exposition de la Maniere Dont se Forment, se Distribuent et se Composent les Richesses. In 1831, he was made professor of political economy at the College de France. In 1828-1830 Say published his Cours Complet d'Economie Politique Pratique.
