1. What is Price Elasticity?

Price elasticity of demand (E_p) measures how responsive the quantity demanded of a good is to changes in its price. It quantifies the percentage change in quantity demanded relative to a percentage change in price.

2. How Does the Calculator Work?

The calculator uses the price elasticity formula:

\[ E_p = \frac{\Delta Q / Q}{\Delta P / P} \]

Where:

\( E_p \) — Price elasticity of demand (dimensionless)
\( \Delta Q \) — Change in quantity demanded
\( Q \) — Initial quantity demanded
\( \Delta P \) — Change in price
\( P \) — Initial price

Explanation: The formula calculates the ratio of percentage change in quantity to percentage change in price, indicating how sensitive demand is to price changes.

3. Importance of Price Elasticity

Details: Understanding price elasticity helps businesses set optimal prices, forecast revenue changes, and develop effective pricing strategies. It also aids in economic analysis and market research.

4. Using the Calculator

Tips: Enter the change in quantity, initial quantity, change in price, and initial price. Select between arc elasticity (for discrete changes) or point elasticity (for marginal analysis). All values must be valid (quantities and prices > 0).

5. Frequently Asked Questions (FAQ)

Q1: What do different elasticity values mean?
A: |E_p| > 1: elastic demand; |E_p| < 1: inelastic demand; |E_p| = 1: unit elastic; E_p = 0: perfectly inelastic.

Q2: What's the difference between arc and point elasticity?
A: Arc elasticity measures elasticity over a range, while point elasticity measures at a specific point on the demand curve.

Q3: What factors affect price elasticity?
A: Availability of substitutes, necessity vs luxury, time horizon, proportion of income spent, and brand loyalty.

Q4: How is elasticity related to total revenue?
A: For elastic demand, price increase reduces revenue; for inelastic demand, price increase increases revenue.

Q5: Can elasticity be negative?
A: Yes, for normal goods elasticity is negative (price and quantity move in opposite directions), but we often use absolute value.
