c. How does the contract curve change when Consumer 1 has the utility function as U (X,Y) = X²Y while the other consumer's preferences are as before? Derive the equation for the contract curve.

d. 有低概率會捐失(5%概率失10元)

a. What does a contract curve(契約曲線) on the Edgeworth Box represent?

b. Derive the equation for the contract curve when each consumer has Cobb-Douglas preferences given by U (X,Y) = XY.

d. Demonstrate the two contract curves on the Edgeworth Box and explain where does the difference between these two contract curves. marginal cost of providing golf service is constant and low, use a graph to demonstrate how this monopolist maximize its profit without any form of price discrimination. What if this monopolist can practice price discrimination using two-part tarif(两部定價法)?What is strategy chosen by this monopolist. Which scenario (with and without two-part tarift) generate a larger social surplus? Show your results on the graph.

3. Consider a scenario of a golf club which serves as a monopolist in the local market and it faces a downward sloping demand curve. Assume that the marginal cost of providing golf service is constant and low, use a graph to demonstrate how this monopolist maximize its profit without any form of price discrimination. What if this monopolist can practice price discrimination using two-part tarif(兩部定價法)?What is strategy chosen by this monopolist. Which scenario (with and without two-part tarift) generate a larger social surplus? Show your results on the graph.
