If the price of Good Y falls from $10 to $8, and the quantity supplied of it falls from 1,000 units to 600 units, the price elasticity of supply is:

Price elasticity of supply = 2.25

Explanation:

Price elasticity of supply is defined as the degree to which quantity of a product supplied is sensitive to changes in price.

In a competitive market when the price of a good increases its supply also increases. This is because suppliers want to make more profit from the higher product price.

Price elasticity of supply = %∆ Quantity ÷ %∆ price

Price elasticity of supply = {(600 - 1000) ÷ (1000 + 600)/2}/ {(8 - 10) ÷ (10+8)/2}

Price elasticity of supply = -0.5 ÷ -0.2222

Price elasticity of supply = 2.25
