Elasticity (Supply) Flashcards
What is the price elasticity of supply ?
Responsiveness of a change in supply to a change in price
What is the Formula for PES?
PES=%(change)QS/%(change)P
If price is elastic ..
PES>1, firms can increase supply at little cost
If supply is inelastic…
PES<1, an increase in supply will be expensive
A perfectly inelastic supply has …
PES=0
Supply is perfectly elastic when …
PES=Infinity
Factors influencing PES:

-Spare capacity
-Barriers to entry
-How substitute able factors are
