An elastic demand or elastic supply is one in which the elasticity is greater than one, indicating a high responsiveness to changes in price. An inelastic demand or inelastic supply is one in which elasticity is less than one, indicating low responsiveness to price changes.
Demand is price elastic in the upper half of any linear demand curve and price inelastic in the lower half. It is unit price elastic at the midpoint. When demand is price inelastic, total revenue moves in the direction of a price change.
If supply is elastic, an increase in demand will cause only a small rise in price, but a significant increase in demand. If supply is inelastic, an increase in demand will cause a large rise in price but only a small increase in demand.
Elasticity of demand occurs when demand responds to changes in price or other economic factors. Inelasticity of demand means that demand remains relatively constant even with changes in...
An elastic demand or elastic supply is one in which the elasticity is greater than one, indicating a high responsiveness to changes in price. Elasticities that are less than one indicate low responsiveness to price changes and correspond to inelastic demand or inelastic supply.
We can understand these changes by graphing supply and demand curves and analyzing their properties. Toilet paper is an example of an elastic good. Image courtesy of Nic Stage on Flickr. Keywords: Elasticity; revenue; empirical economics; demand elasticity; supply elasticity.
Elasticity of demand is usually just comparing what happens to demand when a goods price is changed. For example, with a can of soda, you can use elasticity to measure what would happen to demand if you raised the price (say you charged $1.25 instead of $1.00 for instance).
In microeconomics, whether demand is elastic or inelastic depends on factors like changes in price, substitute availability, and income level. Learn about elasticity of demand, inelasticity of demand, and the differences between the two terms.
1. Price Elasticity of Demand. Price elasticity of demand measures the percentage change in quantity demanded of a good relative to a percentage change in its price. It is also called own-price elasticity of demand, E _ {D} D or PED. Price elasticity of demand is measured as the absolute value of the ratio of these two changes.
An inelastic supplier (one with a steeper supply curve) will always supply the same amount of goods, regardless of the price, and an elastic supplier (one with a flatter supply curve) will change quantity supplied in response to changes in price. How Is Elasticity Measured?
