What does the price elasticity of supply mean? How do we measure it?

#### Solution

Price elasticity of supply (es) is defined as the degree of the responsiveness of quantity supplied, to the change in the price of a good.

It is expressed as:-

e_s="Percentage change in quality supplied"/"Percentage change in price"

=((DeltaQ)/Qxx100)/((DeltaP)/Pxx100)

=(DeltaQ)/QxxP/(DeltaP)

=(DeltaQ)/(DeltaP)xxP/Q

Where

ΔQ = change in quantity supplied

ΔP = change in price

P = initial price

Q = initial supply
