The Nixon shock refers to the effect of a series of economic measures, including wage and price freezes, surcharges on imports, and the unilateral cancellation of the direct international convertibility of the United States dollar to gold, taken by United States President Richard Nixon in 1971 in response to increasing inflation.

Price controls are restrictions set in place and enforced by governments, on the prices that can be charged for goods and services in a market. The intent behind implementing such controls can stem from the desire to maintain affordability of goods even during shortages, and to slow inflation, or, alternatively, to ensure a minimum income for providers of certain goods or to try to achieve a living wage. There are two primary forms of price control: a price ceiling, the maximum price that can be charged; and a price floor, the minimum price that can be charged. A well-known example of a price ceiling is rent control, which limits the increases that a landlord is permitted by government to charge for rent. A widely used price floor is minimum wage. Historically, price controls have often been imposed as part of a larger incomes policy package also employing wage controls and other regulatory elements.
