Incomes policies have often been resorted to during wartime. During the French Revolution, "The Law of the Maximum" imposed price controls (by penalty of death) in an unsuccessful attempt to curb inflation, and such measures were also attempted after World War II. Peacetime income policies were resorted to in the US in August 1971 as a response to inflation. The wage and price controls were effective initially but were made less restrictive in January 1973, and later removed when they seemed to be having no effect on curbing inflation. Incomes policies were successful in the United Kingdom during World War II but less successful in the post-war era.
