3.4 Elasticity of Supply Lecture

What does supply elasticity measure in economics?

It measures how the quantity supplied responds to a change in price.

How is elasticity of supply quantified?

It is quantified by the percent change in quantity supplied divided by the percent change in price.

If a supply curve has an elasticity of 0.5, what does this indicate about price changes?

A 10% increase in price results in a 5% increase in quantity supplied.

What does an elasticity of 2 signify?

A 10% price increase leads to a 20% increase in quantity supplied.

What can be said about the relationship between elasticity and responsiveness of supply to price changes?

Greater elasticity indicates a larger responsiveness of quantity supplied to price changes.

What is the implication of a perfectly inelastic supply (elasticity = 0)?

The quantity supplied remains constant regardless of price changes.

What is a characteristic of inelastic supply (elasticity between 0 and 1)?

A significant price change results in a minor change in quantity supplied.

What happens in elastic supply (elasticity greater than 1)?

A small price change leads to a large change in quantity supplied.

What is a theoretical situation where supply elasticity is infinite?

Perfectly elastic supply, where even tiny changes in price yield extreme changes in quantity supplied.

How do inventories and storability affect price elasticity of supply?

Storable products typically have more elastic supply as suppliers can adjust more easily to price changes.

What is a factor that influences the elasticity related to available inputs?

The ease of accessing inputs and scaling production influences elasticity.

How does easy entry and exit in a market impact elasticity?

It tends to make supply more elastic.

What is the trend in price elasticity of supply over time?

It is generally higher over longer timeframes as businesses can adjust their supply strategies.
