Price
Prices tend to be regulated by the law of supply and demand; that is, a price of a good or service increases with smaller supply and/or greater demand. A corollary to this is the idea that commoditization drives prices down because it increases supply (sometimes vastly) while leaving demand the same. Prices likewise rise when the value of money declines. Governments can and have controlled the prices of certain goods and services by subsidy or decree. This is usually an anti-inflationary measure and tends to distort, rather than eliminate, the law of supply and demand. It is thus not generally sustainable as a mechanism for controlling price.
