The Mont Pelerin Society (MPS) is an international organization composed of economists, philosophers, historians, intellectuals and business leaders. The members see the MPS as an effort to interpret in modern terms the fundamental principles of economic society as expressed by classical Western economists, political scientists and philosophers. Its founders included Friedrich Hayek, Frank Knight, Karl Popper, Ludwig von Mises, George Stigler and Milton Friedman. The society advocates freedom of expression, free market economic policies and the political values of an open society. Further, the society seeks to discover ways in which the private sector can replace many functions currently provided by government entities.
