Suppose that over the past ten years price of Kona coffee increased by 20% and the total number of pounds of Kona coffee sold on the market increased by 5%.
1. Calculate price elasticity of demand for Kona coffee using this information.
2. Calculate price elasticity of supply.
1.Price elasticity of demand
Percentage change in price=20℅
Percentage change in quantity demanded=5℅
Price elasticity of demand=percentage change in quantity demanded ÷ percentage change in price
=5÷20
=0.25
2.Price elasticity of supply
Percentage change in price=20%
Percentage change in quantity supplied=5%
Price elasticity of supply= percentage change in quantity supplied ÷ percentage change in price
=5÷20
=0.25
While calculating I have taken percentage change in quantity demand to be equal to percentage change in quantity supplied.
