Definition
Price inelasticity refers to the characteristic of a product or service where the quantity demanded remains relatively constant despite changes in its price. This concept is especially important in market analysis, pricing strategies, and understanding consumer behavior.
Detailed Explanation
Price inelasticity of demand implies that a change in price leads to a proportionately weaker response in the quantity demanded. This phenomenon is typically quantified using the price elasticity of demand (PED), which is calculated using the following formula:
\[ \text{Price Elasticity of Demand} (PED) = \frac{% \text{ Change in Quantity Demanded}}{% \text{ Change in Price}} \]
When the absolute value of PED is less than 1, the demand is considered price inelastic, meaning changes in price have a minimal impact on the quantity demanded.
Examples
-
Necessities: Goods such as gasoline, prescription medications, and basic food items are often price inelastic. Even if prices increase significantly, consumers will continue to purchase nearly the same quantity because these goods are essential for daily life.
-
Addictive Products: Tobacco products and alcohol can exhibit price inelasticity because consumers, particularly those with addictions, are less sensitive to price changes.
-
Unique Services or Goods: Certain luxury items or services with no close substitutes, like exclusive concert tickets or rare antiques, may be price inelastic because their unique value to buyers outweighs cost considerations.
Frequently Asked Questions (FAQs)
What causes price inelasticity?
Various factors can cause price inelasticity, including the necessity of the product, lack of substitutes, addictiveness, and the proportion of a consumer’s budget spent on the good.
How does price inelasticity affect pricing strategy?
Firms facing inelastic demand curves can increase prices without a substantial loss in sales volume, potentially increasing overall revenue. Conversely, reducing prices might not significantly boost sales volume when demand is inelastic.
Can price inelasticity change over time?
Yes, factors such as the introduction of substitutes, changes in consumer preferences, or shifts in consumer income can alter the price elasticity of a product over time.
Is price inelasticity common in all markets?
No, price inelasticity is more prevalent in markets for essential goods and services, unique products, and items with addictive attributes. Other markets, especially those with many substitutes, tend to exhibit more price elastic demand.
-
Price Elasticity of Demand (PED): Measures the responsiveness of the quantity demanded to a change in price.
-
Income Elasticity of Demand: Measures the responsiveness of the quantity demanded to a change in consumer income.
-
Cross Elasticity of Demand: Measures the responsiveness of the quantity demanded of one good to a change in the price of another good.

Fundamentals of Price Inelasticity: Economics Basics Quiz
### What is an indicator of price inelasticity?
- [ ] Large change in quantity demanded due to price change.
- [x] Small change in quantity demanded despite price change.
- [ ] Quantity demanded remains perfectly constant.
- [ ] Revenue remains constant with price changes.
> **Explanation:** Price inelasticity is characterized by only a small change in quantity demanded in response to a change in price.
### Which factor does NOT typically lead to price inelasticity?
- [ ] Necessity of the product
- [ ] Lack of substitutes
- [ ] Addictive nature of the product
- [x] High number of substitutes
> **Explanation:** A high number of substitutes typically leads to price elasticity, not inelasticity.
### What is a key characteristic of a good with inelastic demand?
- [x] It is essential for daily life.
- [ ] It is a luxury item.
- [ ] It has many substitutes.
- [ ] It has elastic supply.
> **Explanation:** Goods essential for daily life often have inelastic demand because consumers will continue to buy nearly the same amount regardless of price changes.
### How might a company respond to inelastic demand in terms of pricing strategy?
- [ ] Decrease prices to increase sales volume.
- [x] Increase prices to maximize revenue.
- [ ] Keep prices constant.
- [ ] Focus on advertising to compete with substitutes.
> **Explanation:** For goods with inelastic demand, companies might increase prices without losing significant sales volume, thus maximizing revenue.
### Why is gasoline often considered price inelastic?
- [ ] It is a luxury item.
- [x] It lacks close substitutes and is essential for many consumers.
- [ ] It has many substitutes.
- [ ] It is a seasonal good.
> **Explanation:** Gasoline is considered price inelastic because it is essential for many people and lacks close substitutes.
### The price elasticity of demand formula yields an absolute value less than 1. What does this signify?
- [x] The demand is inelastic.
- [ ] The demand is elastic.
- [ ] The demand is perfectly elastic.
- [ ] The demand is unitary elastic.
> **Explanation:** An absolute value of PED less than 1 indicates that the demand is inelastic.
### If a product has inelastic demand, what typically happens to total revenue when the price increases?
- [x] Total revenue increases.
- [ ] Total revenue decreases.
- [ ] Total revenue remains the same.
- [ ] Total revenue fluctuates unpredictably.
> **Explanation:** When demand is inelastic, increasing the price often leads to an increase in total revenue because the decrease in quantity demanded is proportionately smaller.
### What might change a product’s demand from inelastic to elastic over time?
- [ ] Decreased consumer income.
- [ ] Increase in addiction to the product.
- [x] Introduction of close substitutes.
- [ ] The product becoming a greater necessity.
> **Explanation:** The introduction of close substitutes can make the demand for a product more elastic over time.
### Which of the following would likely have the most inelastic demand?
- [ ] Luxury watches
- [ ] Designer clothes
- [x] Water utilities
- [ ] Movie tickets
> **Explanation:** Water utilities typically have the most inelastic demand since they are essential and lack substitutes.
### In which scenario might demand become more inelastic?
- [ ] When consumer preferences shift away from the product.
- [ ] When a product becomes obsolete.
- [x] When a product becomes a legal requirement.
- [ ] Introduction of generic brands for the product.
> **Explanation:** When a product becomes a legal requirement, consumers must purchase it regardless of price changes, making the demand more inelastic.
