Key Concepts in Microeconomics: Consumer Theory and Market Welfare

Four Properties

1.
Higher indifference curves are preferred to lower ones.
2. Indifference curves cannot cross
3. Indifference curves are downward sloping.
4. Indifference curves are bowed inward –convexity-

Tangency Condition


MRS = P1 / P2 ​

Consumer’s Optimal Choice


MU1 / MU2 = P1 / P2 ​

Proportionality Rule


MU1 / P1 = MU2 / P2 ​

Perfect Substitutes:


Indifference curves are straight lines. Optimal choice is at one extreme (all of one good).

Perfect Complements:


Indifference curves are L-shaped.
