Elasticity of Demand
The relative stability of a security's or product's price in the face of increased or decreased demand. Elastic securities or products have prices that move as independently as possible from changes in demand. In securities, elasticity is strongly influenced by the number of shares outstanding; if a company has many shares outstanding, a large order to buy or sell them is less likely to affect the price as strongly as a similar order for a company with comparatively few shares outstanding. In other products, elasticity largely comes from whether a given product is considered a necessity or a luxury. A "necessary" product is likely to be more elastic. See also: Income Elasticity of Demand.
The responsiveness of the quantity purchased of an item to changes in the item's price. If the quantity purchased changes proportionately more than the price, the demand is elastic. If the quantity purchased changes proportionately less than the price, the demand is inelastic. For example, price increases by cigarette manufacturers have a relatively small effect on cigarette consumption, thus, the demand for cigarettes is inelastic.
The ability of the real estate market to respond to price increases over a fairly short period of time.
