Question 1

What is perfectly elastic supply and how does it appear on a supply curve?

Accepted Answer

Perfectly elastic supply occurs when even a small price increase leads to an infinite quantity supplied, while any price decrease drops it to zero. The supply curve is horizontal, and producers will supply any quantity at the prevailing price. The elasticity value is infinity, indicating complete responsiveness to price changes.

Question 2

How does relatively elastic supply differ from unitary elastic supply?

Accepted Answer

Relatively elastic supply has a percentage change in quantity supplied that exceeds the percentage change in price, with elasticity greater than one and a flatter supply curve. Unitary elastic supply shows equal percentage changes in both quantity and price, with elasticity equal to one. The unitary elastic curve's slope depends on the relative scale of axes, but the ratio of changes must be exactly the same.

Question 3

What characterizes perfectly inelastic supply in the market?

Accepted Answer

Perfectly inelastic supply means the quantity supplied remains constant regardless of price changes. The supply curve is vertical, and the elasticity is zero. Producers cannot or will not adjust output in response to price fluctuations, making supply completely unresponsive to market price movements.

Question 4

Why is understanding elasticity of supply important for business decision-making?

Accepted Answer

Understanding elasticity of supply helps businesses predict market responses to price changes and make informed production and pricing decisions. By knowing whether supply is elastic or inelastic, companies can anticipate how quantity supplied will react to price adjustments and plan inventory, production capacity, and pricing strategies accordingly.

Question 5

How does relatively inelastic supply behave compared to elastic supply?

Accepted Answer

Relatively inelastic supply has a percentage change in quantity supplied that is less than the percentage change in price, with elasticity between zero and one. The supply curve is steeper than elastic supply. This indicates producers are less responsive to price changes, adjusting output minimally when prices fluctuate.

Question 6

What does the slope of a supply curve indicate about price responsiveness?

Accepted Answer

A flatter supply curve indicates greater price responsiveness, characteristic of elastic supply where quantity supplied changes more than proportionately to price changes. A steeper supply curve indicates lower price responsiveness, characteristic of inelastic supply where quantity supplied changes less than proportionately. The elasticity of supply through percentage method quantifies this responsiveness precisely.

Question 7

How do the five degrees of elasticity relate to supply curve shapes?

Accepted Answer

The five degrees of elasticity produce distinct supply curve shapes: perfectly elastic is horizontal, relatively elastic is flatter, unitary elastic is diagonal, relatively inelastic is steeper, and perfectly inelastic is vertical. Each shape visually represents how quantity supplied responds to price changes, with elasticity values ranging from infinity to zero across these categories.
