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 regulation, 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 economy, 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.
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. Paths to Democracy: Revolution and Totalitarianism By Rosemary H.T. O'Kane, p. 135
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 Nixon shock. The constitutionality of this action was challenged and upheld in the case of Amalgamated Meat Cutters v. Connally.
The individual states have sometimes chosen to implement their own control policies. In the 1860s, several midwestern states of the United States, namely Minnesota, Iowa, Wisconsin, and Illinois, enacted a series of laws called the Granger Laws, primarily to regulate rising fare prices of railroad and grain elevator companies. The state of Hawaii briefly introduced a cap on the wholesale price of gasoline (the Gas Cap Law) in an effort to fight "price gouging" in that state in 2005. Because it was widely seen as too soft and ineffective, it was repealed shortly thereafter.
Advantages of a price floor are:
Disadvantages of a price floor are:
Further problems can occur if a government sets unrealistic price ceilings, causing business failures, stock crashes, or even economic crises. In fully unregulated market economies, price ceilings do not exist. While price ceilings are often imposed by governments, there are also price ceilings that are implemented by non-governmental organizations such as companies, such as the practice of resale price maintenance. With resale price maintenance, a manufacturer and its agree that the distributors will sell the manufacturer's product at certain prices (resale price maintenance), at or below a price ceiling (maximum resale price maintenance) or at or above a price floor.
As with Diocletian's Edict on Maximum Prices, shortages lead to where prices for the same good exceed those of an uncontrolled market. Furthermore, once controls are removed, prices will immediately increase, which can temporarily shock the economic system. Black markets flourish in most countries during . States that are engaged in total war or other large-scale, extended often impose restrictions on home use of critical resources that are needed for the war effort, such as food, gasoline, rubber, metal, etc., typically through rationing. In most cases, a black market develops to supply rationed goods at exorbitant prices. The rationing and price controls enforced in many countries during World War II encouraged widespread black market activity.
A classic example of how price controls cause shortages was during the Arab oil embargo between October 19, 1973, and March 17, 1974. Long lines of cars and trucks quickly appeared at retail gas stations in the U.S. and some stations closed because of a shortage of fuel at the low price set by the U.S. Cost of Living Council. The fixed price was below what the market would otherwise bear and, as a result, the inventory disappeared. It made no difference whether prices were voluntarily or involuntarily posted below the market clearing price. Scarcity resulted in either case. Price controls have been criticised as failing to achieve their proximate aim by some opponents of the policy or strategy, which is enacted to reduce prices paid by retail consumers, but such controls in certain circumstances may cause side effects which can reduce supply.Taylor and Van Doren, pp. 26–28Thomas Sowell, Applied Economics: Thinking Beyond Stage One (2008), pp. 7–9, 112–113, Nobel Memorial Prize winner Milton Friedman said, "We economists don't know much, but we do know how to create a shortage. If you want to create a shortage of tomatoes, for example, just pass a law that retailers can't sell tomatoes for more than two cents per pound. Instantly you'll have a tomato shortage. It's the same with oil or gas.""Controls blamed for U.S. energy woes", Los Angeles Times, February 13, 1977, Milton Friedman press conference in Los Angeles.
U.S. President Richard Nixon's Secretary of the Treasury, George Shultz, enacting Nixon's "New Economic Policy", lifted price controls that had begun in 1971 (part of the "Nixon Shock"). This lifting of price controls resulted in a rapid increase in prices. Price freezes were re-established five months later. Stagflation was eventually ended in the United States when the Federal Reserve under chairman Paul Volcker raised interest rates to unusually high levels. This successfully ended high inflation but caused a recession that ended in the early 1980s.
