Unit elasticity, a critical concept in economics, measures the proportional change in quantity demanded or supplied in response to a proportional change in price. It is closely related to elasticity of demand, price elasticity of supply, inelastic demand, and elastic demand.
Unit Elasticity in Economics
Unit elasticity is a concept in economics that describes the relationship between the price of a good or service and the quantity demanded of that good or service. It measures the responsiveness of demand to changes in price.
Definition
Unit elasticity occurs when the percentage change in the quantity demanded is equal to the percentage change in the price. In other words, a 1% change in price leads to a 1% change in quantity demanded.
Elasticity Coefficient
The elasticity coefficient is a measure of elasticity. It is calculated as the percentage change in quantity demanded divided by the percentage change in price. A coefficient of 1 indicates unit elasticity.
Factors Affecting Elasticity
The elasticity of demand for a good or service can be affected by several factors:
- Availability of substitutes: If there are close substitutes for a product, demand will be more elastic.
- Necessity: Goods and services that are necessities tend to have inelastic demand.
- Time frame: Elasticity can vary depending on the time frame considered.
Types of Elasticity
- Elastic: Demand is elastic when a change in price leads to a larger percentage change in quantity demanded.
- Inelastic: Demand is inelastic when a change in price leads to a smaller percentage change in quantity demanded.
- Perfectly elastic: Demand is perfectly elastic when any increase in price results in zero quantity demanded.
- Perfectly inelastic: Demand is perfectly inelastic when any change in price has no effect on quantity demanded.

| Elasticity Coefficient | Description |
|---|---|
| >1 | Elastic |
| =1 | Unit elastic |
| <1 | Inelastic |
| =0 | Perfectly inelastic |
| =∞ | Perfectly elastic |
Question 1:
What is the precise definition of “unit elastic” in economics?
Answer:
Unit elasticity refers to a demand curve where the percentage change in quantity demanded is equal to the percentage change in price. In other words, when the price of a good or service changes by 1%, the quantity demanded also changes by 1%.
Question 2:
How is unit elasticity measured?
Answer:
Unit elasticity is measured using the elasticity coefficient, which is the ratio of the percentage change in quantity demanded to the percentage change in price. A coefficient value of 1 indicates unit elasticity.
Question 3:
What are the implications of unit elasticity for businesses?
Answer:
Unit elasticity implies that changes in price will have a proportionate effect on revenue. Businesses may increase revenue by raising or lowering prices, but the total change in revenue will be zero since the change in quantity demanded will offset the change in price.
Well, there you have it, folks! Unit elasticity is all about that sweet spot where a price change results in the exact same percentage change in quantity demanded.
