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.
