Price controls

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 (wages are the price of labor). Historically, price controls have often been imposed as part of a larger incomes policy package also employing wage controls and other regulatory elements.

Although price controls are routinely used by governments, Western economists generally agree that consumer price controls do not accomplish what they intend to in market economies, and many economists instead recommend such controls should be avoided; however, since the credibility revolution started in the 1990s, minimum wages have found strong support among some economists.

The Roman Emperor Diocletian tried to set maximum prices for all commodities in the late 3rd century AD but with little success. In the early 14th century, the Delhi Sultanate ruler Alauddin Khalji instituted several market reforms, which included price-fixing for a wide range of goods, including grains, cloth, slaves and animals. However, a few months after his death, these measures were revoked by his son Qutbuddin Mubarak Shah. During the French Revolution, the Law of the Maximum set price limits on the sale of food and other staples. Within Spain in the 16th and 17th centuries, after the price revolution, a permanent regulation on the price of wheat (called tasa del trigo) was established. This intervention was discussed by theologians and jurists of this time.

Governments in planned economies typically control prices on most or all goods but have not sustained high economic performance and have been almost entirely replaced by mixed economies. Price controls have also been used in modern times in less-planned economies, such as rent control. During World War I, the United States Food Administration enforced price controls on food. Price controls were also imposed in the US and Nazi Germany during World War II.

Wage controls have been tried in many countries to reduce inflation, seldom with success. Since inflation can be caused by both aggregate supply or demand, wage controls can fail as a result of supply shocks or excessive stimulus during times of high sovereign debt (increases to the Monetary Aggregate System M2).

The National Board for Prices and Incomes was created by the government of Harold Wilson in 1965 in an attempt to solve the problem of inflation in the British economy by managing wages and prices. The Prices and Incomes Act 1966 c. 33 affected UK labour law, regarding wage levels and price policies. It allowed the government to begin a process to scrutinise rising levels of wages (then around 8% per year) by initiating reports and inquiries and ultimately giving orders for a standstill. The objective was to control inflation. It proved unpopular after the 1960s.

In the United States, price controls have been enacted several times. The first time price controls were enacted nationally was in 1906 as a part of the Hepburn Act.^{[page needed]} In World War I the War Industries Board was established to set priorities, fix prices, and standardize products to support the war efforts of the United States. During the 1930s, the National Industrial Recovery Act (NIRA) created the National Recovery Administration, that set prices and created codes of "fair practices". In May 1935, the Supreme Court held that the mandatory codes section of NIRA were unconstitutional, in the court case of Schechter Poultry Corp. v. United States.

During World War II, the Office of Price Administration handled price controls. During the Korean War, the Economic Stabilization Agency instituted price controls. In 1971, President Richard Nixon issued Executive Order 11615 (pursuant to the Economic Stabilization Act of 1970), imposing a 90-day freeze on wages and prices. The constitutionality of this action was challenged and upheld in the case of Amalgamated Meat Cutters v. Connally.
