Arc Elasticity Formula:
| From: | To: |
Arc elasticity measures the responsiveness of quantity demanded to price changes between two points on a demand curve. It provides a more accurate measure than point elasticity when dealing with significant price or quantity changes.
The calculator uses the arc elasticity formula:
Where:
Explanation: The formula calculates the percentage change in quantity divided by the percentage change in price, using the initial values as the base for both calculations.
Details: Understanding price elasticity helps businesses set optimal prices, predict revenue changes, and understand consumer behavior. It's essential for pricing strategies and market analysis.
Tips: Enter initial and new quantities and prices in the appropriate fields. All values must be positive numbers. The calculator will compute the arc elasticity coefficient.
Q1: What does the elasticity value indicate?
A: Values greater than 1 indicate elastic demand (quantity changes more than price), values less than 1 indicate inelastic demand, and exactly 1 indicates unit elasticity.
Q2: How is arc elasticity different from point elasticity?
A: Arc elasticity measures elasticity between two points on a demand curve, while point elasticity measures at a specific point. Arc elasticity is better for larger price changes.
Q3: Can elasticity be negative?
A: Yes, but typically we use the absolute value when discussing price elasticity of demand since the relationship between price and quantity is usually inverse.
Q4: What factors influence price elasticity?
A: Availability of substitutes, necessity of the product, proportion of income spent, and time period considered all affect elasticity.
Q5: How is elasticity used in business decisions?
A: Businesses use elasticity to determine optimal pricing, predict revenue changes from price adjustments, and understand market competitiveness.
