PRICE CONTROLS: Government intervention in markets in which legal restrictions are placed on the prices charged. The two basic types of price controls are price ceilings and price floors. Price ceilings are maximum prices set below the equilibrium price. Price floors are minimum prices set above the equilibrium price. Price controls imposed on an otherwise efficient and competitive market create imbalances (shortages or surpluses) which cause inefficiency. However, imposing price controls on a market that fails to achieve efficiency (due to market control, externalities, or imperfect information) can actual improve efficiency. Price controls have also be used economy-wide in an attempt to reduce inflation.

                           ELASTIC SUPPLY: The general supply relation in which relatively small changes in price cause relatively large changes in quantity supplied. Small changes in price cause relatively large changes in quantity supplied or the percentage change in quantity supplied is larger than the percentage change in price. This characterization of elasticity is most important for the price elasticity of supply. Elastic supply is one of two general elasticity relations for supply. The other is inelastic supply. An elastic supply relation is a very responsive, or stretchable, relation. The elastic relation is most often directed toward supply in terms of the price elasticity of supply. In this context, supply is said to be elastic if the percentage change in quantity is larger than the percentage change in price. This means that sellers are responsive to price changes.An elastic supply relation can fall into one of two categories--perfectly elastic and relatively elastic. - Perfectly Elastic: Perfectly elastic means an infinitesimally small change in price results in an infinitely large change in quantity supplied. This elasticity alternative exists when the price is fixed, that is, an infinite range of quantities is associated with the same price. This is the extreme, limiting case of elastic. Perfectly elastic supply can occur, in theory, when producers are able to switch resources among a large number of perfect substitutes-in-production.
- Relatively Elastic: Relatively elastic means that relatively small changes in price cause relatively large changes in quantity. Quantity is very responsive to price, but not infinitely so. The percentage change in quantity supplied is greater than the percentage change in price. Relatively elastic supply occurs when producers are able to switch resources among a large number of close but not perfect substitutes-in-production.

GRAY SKITTERY
[What's This?]
Today, you are likely to spend a great deal of time at a garage sale trying to buy either a coffee cup commemorating the 2000 Olympics or a birthday gift for your grandmother. Be on the lookout for strangers with large satchels of used undergarments.
