Definition
Inelastic Supply
Inelastic supply occurs when the quantity of a good or service that producers are willing to sell changes minimally in response to price changes. In other words, the price elasticity of supply is less than one. This scenario is common for goods that have limited production capacity or involve long-term investments, such as rental housing or nuclear energy facilities.
Inelastic Demand
Inelastic demand refers to a situation where the quantity of a good or service demanded by consumers changes very little as its price changes. This implies that the price elasticity of demand is less than one. Goods or services considered essential or with few substitutes, such as basic food items, gasoline, and vital prescription medications, often exhibit inelastic demand.
Examples
- Inelastic Supply Example: A pharmaceutical company producing a specific life-saving drug may have inelastic supply due to production limitations or regulatory constraints. Even if the price increases significantly, the company cannot quickly scale up production.
- Inelastic Demand Example: For a life-saving medication, consumers will continue to purchase it irrespective of price increases, given its necessity and lack of substitutes.
Frequently Asked Questions (FAQs)
What factors contribute to inelastic supply?
- Limited production capacity: If it’s impossible or difficult to increase supply.
- Long-term investments: Items requiring substantial time and capital to produce.
- Regulatory constraints: Restrictions that prevent immediate changes in supply.
What makes demand for a product inelastic?
- Necessity: Essential items with no close substitutes.
- Lack of substitutes: Few or no alternatives available.
- Small proportion of income: Goods that take up a minor part of the consumer’s budget.
How does inelastic supply affect producers?
Producers might not significantly increase production even with price hikes, potentially leading to higher profits during demand surges but also limiting revenue avenues in scalable situations.
How does inelastic demand affect pricing strategy?
With inelastic demand, companies can raise prices without substantially reducing sold quantities, often leading to higher total revenues.
Elasticity of Supply and Demand
The responsiveness of the quantity supplied or demanded of a good to changes in its price.
Price Elasticity of Demand (PED)
The percentage change in quantity demanded resulting from a percentage change in price.
Price Elasticity of Supply (PES)
The percentage change in the quantity supplied resulting from a percentage change in price.
Perfectly Inelastic Supply
A scenario where the quantity supplied does not change no matter the price change (PES = 0).
Perfectly Inelastic Demand
A situation where the quantity demanded remains constant regardless of price changes (PED = 0).

Fundamentals of Inelastic Supply and Demand: Economics Basics Quiz
### Which of the following best describes inelastic demand?
- [ ] A large change in quantity demanded for a small price change.
- [ ] Demand decreases sharply with price increases.
- [ ] Quantity demanded changes very little with price increases.
- [ ] Price changes have no effect on quantity demanded.
> **Explanation:** Inelastic demand describes a situation where the quantity demanded changes very little when the price changes, suggesting that consumers continue to buy nearly the same amount despite price fluctuations.
### Goods with inelastic demand are typically considered?
- [ ] Luxuries
- [x] Necessities
- [ ] Inferior goods
- [ ] Giffen goods
> **Explanation:** Goods with inelastic demand are typically necessities because consumers need them regardless of price changes, such as essential medications or basic food items.
### What happens to total revenue when the price increases for a product with inelastic demand?
- [x] Total revenue increases.
- [ ] Total revenue decreases.
- [ ] Total revenue remains constant.
- [ ] Total revenue fluctuates randomly.
> **Explanation:** For products with inelastic demand, total revenue increases when the price rises since consumers will still purchase nearly the same quantity.
### Which factor is least likely to contribute to inelastic supply?
- [ ] Long production time.
- [ ] Limited production capacity.
- [ ] High regulatory barriers.
- [x] Abundance of substitute goods.
> **Explanation:** Abundance of substitute goods typically affects demand rather than supply. Long production times, limited production capacity, and regulatory barriers are factors that contribute to inelastic supply.
### Price elasticity of demand (PED) and supply (PES) for inelastic goods and services is generally?
- [ ] Greater than 1
- [ ] Exactly 1
- [x] Less than 1
- [ ] Zero
> **Explanation:** For inelastic goods and services, both the price elasticity of demand (PED) and supply (PES) are less than 1, indicating a relatively small response in quantity to price changes.
### Which of these scenarios is typical for a product with perfectly inelastic supply?
- [ ] The quantity supplied changes proportionally with price changes.
- [x] The quantity supplied remains the same regardless of price changes.
- [ ] The quantity supplied decreases as the price increases.
- [ ] The quantity supplied increases only slightly as price increases.
> **Explanation:** In a perfectly inelastic supply situation, the quantity supplied does not change at all in response to price changes (PES = 0).
### What is a real-world example of a product likely to exhibit perfectly inelastic demand?
- [ ] Electronic gadgets
- [ ] Luxury cars
- [x] Life-saving medications
- [ ] Designer clothing
> **Explanation:** Life-saving medications are a real-world example of products with perfectly inelastic demand because their necessity compels consumers to buy them regardless of higher prices.
### In the context of inelastic supply, why might a company struggle to increase production even when prices rise sharply?
- [x] Due to production capacity limitations.
- [ ] Because of high consumer demand elasticity.
- [ ] Due to the competitive market setting.
- [ ] Because of low demand.
> **Explanation:** Companies with inelastic supply often face production capacity limitations that prevent them from increasing output even when prices rise sharply.
### If a government's tax on an inelastically demanded product increases, what is the likely outcome?
- [x] Consumers bear most of the tax burden.
- [ ] Producers bear most of the tax burden.
- [ ] Both consumers and producers share the tax burden equally.
- [ ] The quantity demanded dramatically decreases.
> **Explanation:** When a product has inelastic demand, consumers typically bear most of the tax burden because they will continue to purchase almost the same quantity despite the higher price.
### When analyzing market equilibrium, what is the impact of inelastic demand on equilibrium price and quantity?
- [x] Price changes significantly with little change in quantity.
- [ ] Quantity changes significantly with little change in price.
- [ ] Both price and quantity change proportionally.
- [ ] Neither price nor quantity changes significantly.
> **Explanation:** In markets with inelastic demand, price typically changes significantly with only a small change in the quantity demanded, affecting the equilibrium price and quantity minimally influencing the latter.
