Jean-Baptiste Say's Letters to Malthus is comprised of five letters written to a fellow classical economist in 1821. The letters present one side of their discussion on political economy. Say's correspondence gives a glimpse into the importance of political economics in nineteenth century Europe. French economist JEAN-BAPTISTE SAY (1767-1832) believed in the open-market system, supporting fewer laws putting restraints on businesses. Say's Law, which states that "supply creates its own demand," was named after Jean-Baptiste although the idea did not originate with him. He wrote A Treatise on Political Economy (1803).
