Elasticity Of Demand
Definition: The degree of buyers' responsiveness to price changes. Elasticity is measured as the percent change in quantity divided by the percent change in price.

Goods with a small value of elasticity (less than 1) have a demand that is insensitive to price, e.g., food, where a rise in price has little or no effect on the quantity demanded by buyers.

Definition: The degree of producers' responsiveness to price changes. Elasticity is measured as the percent change in quantity divided by the percent change in price.

Goods with a small value of elasticity (less than 1) have a supply that is insensitive to price, e.g., food, where a rise in price has little or no effect on the amount that producers supply.
