Economists are trained in theory, statistics, modeling, and other skills. Historians are trained in the careful scrutiny and interpretation of historical sources. Neither economists nor historians, unfortunately, are trained to use common sense in their work. Postwar proponents of the reimposition of price controls have often pointed to the success of such controls during the war. Yet, despite thousands of employees and an army of volunteer monitors associated with the Office of Price Administration and despite the U.S. Attorney General’s prosecutory zeal in hauling alleged violators into court, the government’s price-control efforts during World War II failed to stem the tide of rising prices set in motion by the huge contemporary increases in the money stock.Price controls, at most, only create a population of liars. True prices continue to do what the existing economic conditions cause them to do. No one can control the amount of precipitation by passing a law against reporting more than a stipulated amount of rain and snow.
This is from Austrian economist Robert Higgs at the Independent Institute on the evils of Price Controls
