The president is able to set price controls. When this is done however it sets an artificial ceiling on the price of goods. When the price set is too high it causes too many of the product to be produced because people can't afford to buy it. When the price being set it too low it causes shortages. in the market place. One example of this is when back in the 1970's the price of gasoline was set at too low of a price. Long lines formed a gas stations and only those who were patient enough to wait in line actually got the gas the needed.
