Liberism (derived from the Italian term liberismo) is a term for the economic doctrine of laissez-faire capitalism first used by the philosopher Benedetto Croce, and popularized in English by the Italian-American political scientist Giovanni Sartori. In Italy, liberism is often identified with the political theories of Gaetano Mosca, Luigi Einaudi and Bruno Leoni. Internationally, liberism has been advocated by the Austrian School of economic theory, for instance by Ludwig von Mises and Friedrich von Hayek.
