1. Find the price elasticity of supply at price of Birr 8 if the supply function is:
Q = 25 – 4P + P2
What is elasticity at Birr 4 and at Birr 5? Interpret the result.
Elasticity of supply:
At P= Birr 8,
Price elasticity of supply being 1.88 implies that supply is elastic.
At P=Birr 4,
Elasticity of supply:
Elasticity of supply being 0.64 implies that supply is inelastic.
At P=Birr 5,
Elasticity of supply:
Elasticity of supply being 1 implies that supply is unit elastic.
