Ordoliberalism is an economic theory that originated in Germany after World War II. It emphasizes the importance of a strong legal framework to ensure fair competition and prevent monopolies. The idea is that the state should create and maintain the conditions for a competitive market, rather than directly intervening in the economy. This approach is often associated with the Freiburg School of economics and figures like Walter Eucken. Ordoliberalism seeks to balance free-market principles with social policies, aiming to promote both economic efficiency and social welfare. It has influenced the economic policies of the European Union and Germany's post-war economic model.
