Document Summary

The market system, also called the price system, performs two important and closely related functions: The adjustment of price is the rationing mechanism in free markets. If a product is in strictly scarce supply, as a single painting is, its price is said to be demand- determined. Its price is determined solely and exclusively by the amount that the highest bidder or highest bidders are willing to pay. On occasion, both governments and private firms decide to use some mechanism other than the market system to ration an item for which there is excess demand at the current price. Preventing price from rising to equilibrium is justified on several grounds: price-gouging is bad, some items are necessities and everyone should be able to buy them at a. In 1973 and 1974, opec imposed an embargo on shipments of crude oil to the united. States, which led to a drastic reduction in the quantity of gasoline available at local gas pumps.
