In an effort to adapt the price control program to postwar reconversion and prepare for its eventual termination Congress in July 1946 extended the life of the Price Control Act of 1942 to June 30, 1947, admonishing the Office of Price Administration and other agencies to use their price powers to promote the earliest practicable balance between production and demand: Congress wanted the control of prices and the use of subsidy powers to be terminated as rapidly as possible.[394] The President was directed to recommend to the Congress legislation needed to establish monetary, fiscal, and other policies adequate to supplement the control of prices and wages during the balance of the fiscal year 1947. A Joint Resolution of March 1947 continued the price control program with regard to sugar until October 31, 1947.[395] Rent control as well as other war production controls continued in effect by the Defense Production Act of 1950 which authorized the President to establish a ceiling or ceilings on the price, rental, commission, rate, fee, charge or allowance paid or received on the sale or delivery, or the purchase or receipt, by or to any person, of any material or service. And the same Act required that the President issue regulations and orders stabilizing wages, salaries, and other compensation.[396] Once the Korean War ended, all controls, price, rent and credit were swept off the statute books. CONTROL OF COMMON CARRIERS Congressional enactments under this head generally fall into three major categories: control of domestic transportation, control of carriage by American ships, and control of foreign vessels in American ports. Our interest is confined exclusively to emergency controls exercisable by the Interstate Commerce Commission and similar federal regulatory agencies.
