Homework Answers

Answer #1

1) Since income elasticity of demand is negative for good Z this represents that as income increases quantity demanded decreases or vice versa Hence, Good Z is Inferior, and as cross price elasticity is positive which means as price of one increases demand for other too increases and vice versa hence, good Z and Y are substitute Hence, second statement is correct

​​​​​​​​​​​2) Income elasticity of demand=% change in quantity demanded/% change in income gives % change in quantity demanded=Income elasticity of demand*% change in Consumer income=2.1*-3=-6.3% so demand decreases by 6.3% Hence, None of the option is correct

3) Since X is Inferior good, with increase in income demand will fall at the same time increase in supply both combined will definitely bring the equilibrium prices down Hence, statement 2 equilibrium price will definitely decrease is correct
