Perfectly inelastic demand/supply

Definition

Perfectly inelastic demand or supply refers to a situation where the quantity demanded or supplied remains constant regardless of changes in price. This means that consumers will purchase the same amount of a good or service no matter how much the price increases or decreases, while suppliers will provide the same amount regardless of price fluctuations. Such conditions are usually associated with essential goods or services that have no close substitutes.

5 Must Know Facts For Your Next Test

1. Perfectly inelastic demand or supply is represented graphically by a vertical line on a price-quantity graph.
2. Examples of perfectly inelastic demand include life-saving medications or basic necessities where consumers have no alternatives.
3. In perfectly inelastic supply, producers may be limited by factors like production capacity or resource availability that do not change with price.
4. The concept is theoretical; real-world examples are rare, but certain goods can exhibit close to perfectly inelastic characteristics.
5. Understanding perfectly inelastic demand and supply helps economists analyze market behaviors and make predictions about pricing strategies.

Review Questions

• How does perfectly inelastic demand impact consumer behavior when prices change?
  • When demand is perfectly inelastic, consumer behavior remains unchanged despite fluctuations in price. This means that regardless of whether prices rise or fall, consumers will continue to purchase the same quantity of the good. This behavior typically occurs with essential products where consumers have no substitutes available, illustrating that their need for these goods outweighs any consideration of cost.
• Discuss how perfectly inelastic supply can affect market equilibrium and pricing strategies.
  • Perfectly inelastic supply can lead to significant impacts on market equilibrium, especially when demand increases. Since the quantity supplied remains constant regardless of price changes, any upward shift in demand will result in higher prices without an increase in quantity. This creates a scenario where suppliers may benefit from increased revenue per unit sold but must consider long-term strategies to manage their fixed production capacities and potential consumer backlash if prices rise excessively.
• Evaluate the implications of perfectly inelastic demand/supply on public policy and regulation in markets for essential goods.
  • Perfectly inelastic demand and supply have crucial implications for public policy, particularly concerning essential goods like medications and utilities. Policymakers may need to implement regulations like price controls to prevent exploitation during shortages or crises since consumers cannot reduce their consumption regardless of price hikes. This regulatory approach ensures access to essential goods and protects vulnerable populations, highlighting the balance between market forces and social responsibility within economic systems.

A measure of how much the quantity demanded of a good responds to a change in its price, indicating whether demand is elastic, inelastic, or unitary.

Perfectly Elastic Demand: A situation where the quantity demanded changes infinitely with any change in price, resulting in a horizontal demand curve.

Inelastic Supply: A situation where the quantity supplied is not very responsive to changes in price, often depicted as a steep supply curve.
