ZERO-BASE BUDGET: A method of budgeting expenditures in which each expenditure is justified on its overall merits rather than being based on the budget for the previous year. A zero-base budget is most often proposed (but seldom implemented) for governments. Governments generally establish budget expenditures based on expenditures for the previous year. If, for example, budget expenditures last year were $100 billion, the requested budget for this year might be set at $110 billion. The existing $100 billion is a "given" and only the extra $10 billion is justified. With a zero-base budget, the entire $110 billion is justified.

                           ELASTIC DEMAND: The general demand relation in which relatively small changes in price cause relatively large changes in quantity demanded. Small changes in price cause relatively large changes in quantity demanded or the percentage change in quantity demanded is larger than the percentage change in price. This characterization of elasticity is most important for the price elasticity of demand. Elastic demand is one of two general elasticity relations for demand. The other is inelastic demand. An elastic demand relation is a very responsive, or stretchable, relation. The elastic demand relation is most often directed toward demand in terms of the price elasticity of demand. In this context, demand is said to be elastic if the percentage change in quantity is larger than the percentage change in price. This means that buyers are responsive to price changes.An elastic demand 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 demanded. 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 demand can occur, in theory, when buyers have the choice among a large number of perfect substitutes-in-consumption.
- 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 demanded is greater than the percentage change in price. Relatively elastic demand occurs when buyers have the choice among a large number of close but not perfect substitutes-in-consumption.

[What's This?]
Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway looking to buy either a birthday gift for your aunt or a pair of leather sandals that won't cause blisters. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
