| Term | Definition |
|---|---|
| cross-price elasticity | of demand the percentage change in the quantity of good A that is demanded as a result of a percentage change in the price of good B |
| elastic demand | when the elasticity of demand is greater than one, indicating a high responsiveness of quantity demanded or supplied to changes in price |
| elastic supply | when the elasticity of either supply is greater than one, indicating a high responsiveness of quantity demanded or supplied to changes in price |
| elasticity | an economics concept that measures responsiveness of one variable to changes in another variable |
| inelastic demand | when the elasticity of demand is less than one, indicating that a 1 percent increase in price paid by the consumer leads to less than a 1 percent change in purchases (and vice versa); this indicates a low responsiveness by consumers to price changes |
| inelastic supply | when the elasticity of supply is less than one, indicating that a 1 percent increase in price paid to the firm will result in a less than 1 percent increase in production by the firm; this indicates a low responsiveness of the firm to price increases |
| infinite elasticity | the extremely elastic situation of demand or supply where quantity changes by an infinite amount in response to any change in price; horizontal in appearance |
| price elasticity of demand | percentage change in the quantity demanded of a good or service divided the percentage change in price |
| price elasticity of supply | percentage change in the quantity supplied divided by the percentage change in price |
| unitary elasticity | when the calculated elasticity is equal to one indicating that a change in the price of the good or service results in a proportional change in the quantity demanded or supplied |
| zero inelasticity | the highly inelastic case of demand or supply in which a percentage change in price, no matter how large, results in zero change in the quantity; vertical in appearance |
