Neoliberalism, also neo-liberalism, is a term used to signify the late-20th century political reappearance of 19th-century ideas associated with free-market capitalism. The term has multiple, competing definitions, and is often used pejoratively. In scholarly use, the term is frequently undefined or used to characterize a vast variety of phenomena, but is primarily used to describe the transformation of society due to market-based reforms.

In economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations. In an idealized free market economy, prices for goods and services are set solely by the bids and offers of the participants.
