Claude-Frédéric Bastiat (1801 – 1850) was a French economist, writer and a prominent member of the French Liberal School. A member of the French National Assembly, Bastiat developed the economic concept of opportunity cost and introduced the parable of the broken window. He was described as “the most brilliant economic journalist who ever lived” by economic theorist Joseph Schumpeter. As an advocate of classical economics and the economics of Adam Smith, his views favored a free market and influenced the Austrian School. (From Wikipedia)
