01
Front

What does price elasticity of supply measure?

Back

Price elasticity of supply measures how responsive the quantity sellers offer is to a change in price, with other conditions unchanged.

02
Front

What does elastic supply mean?

Back

Supply is elastic when quantity supplied changes by a larger percentage than price: Es>1E_s>1.

03
Front

How does the midpoint method find percentage changes?

Back

For each variable, divide its change by the average of its starting and ending values, then multiply by 100100: % ΔQs=Q2−Q1(Q1+Q2)/2×100\%\,\Delta Q_s=\frac{Q_2-Q_1}{(Q_1+Q_2)/2}\times100, and likewise for price.

04
Front

What does a calculated supply elasticity estimate describe?

Back

The estimate describes responsiveness between the measured observations; it does not guarantee the same response to every price change.

05
Front

How does more time to adjust affect supply elasticity?

Back

Supply is generally more elastic when sellers have more time to respond, because they can adjust production or new firms can enter.

06
Front

How is price elasticity of supply calculated?

Back

It is the percentage change in quantity supplied divided by the percentage change in price: Es=% ΔQs% ΔPE_s=\frac{\%\,\Delta Q_s}{\%\,\Delta P}.

07
Front

Why does supply elasticity have no units?

Back

It has no units because it is a ratio of percentage changes.

08
Front

When is supply unit elastic?

Back

Supply is unit elastic when quantity supplied and price change by the same percentage: Es=1E_s=1.

09
Front

What does inelastic supply mean?

Back

Supply is inelastic when quantity supplied changes by a smaller percentage than price: 0<Es<10<E_s<1.

10
Front

When is supply perfectly inelastic?

Back

Supply is perfectly inelastic when quantity supplied does not respond to price: Es=0E_s=0.

11
Front

Why use the midpoint method for two observations?

Back

It uses the average of the starting and ending values, so it gives the same elasticity whichever direction the comparison is made.

12
Front

How does available production capacity affect supply responsiveness?

Back

Unused machines, workers, storage, or floor space can help a firm increase output quickly. A firm near capacity may need costly investment to expand much.
