Good A
At point a, IC1 and IC2 have the same total utility, whereas at b and c, IC2 (point b)
has a higher utility than IC1 (point c) because more of B can be consumed. However,
an indifference curve shows combinations of goods with the same total utility.

03 Indifference curve 2
Good B

Indifference
curve?

possible not possible


Good A
No, an indifference curve cannot rise because more of A and more of B would be
consumed. This would imply a higher total utility level and, hence, a higher utility
curve.

a IC2 is the highest indifference curve where the whole income is spent.
b lC1 is a lower indifference curve than IC2 even if the whole income is spent.

05 Complements and substitutes

Budget line (Bl) 1
Bl 2
Good A
A and B are substitutes because the cross-price elasticity of demand
%change quantity demanded B
( %change price A ) is positive: Both numerator and denominator are
positive and - consequently - the result, too.

06 Normal and inferior goods

A is a normal good, B an inferior good. Good A has a positive income elasticity of


%change in quantity demanded
