French economist and businessman
Influential French economist and entrepreneur, best known for Say's Law.
Jean-Baptiste Say (1767-1832) was a leading figure in classical economics and a successful businessman. He founded a textile enterprise before turning to economic theory, where his formulation of Say's Law ("supply creates its own demand") became central to market economics. Say's seminal work, "A Treatise on Political Economy", introduced key concepts such as entrepreneurship and factors of production. He served on the Conseil d'État under Napoleon and contributed to early industrial policy. Say's ideas influenced economists like Mill and Bastiat and remain foundational in modern economic thought. His dual career bridged practical commerce and academic inquiry.
