9.1What do you understand Pareto efficient allocation to be?

9.2. Explain what a contract curve is in terms of economic efficiency.

9.3. With reference to the Edgeworth box theory, draw a typical contract curve between two

clothing for each.

Tip: In the diagram, you must show the points of tangency between each of their

indifference curves to derive the contract curve.
