1. True, false, or uncertain: If some firms in an industry have high marginal costs, c_H, and others have low marginal costs, c_L < c_H , then a merger between two low-cost firms is always more profitable than the merger between a low-cost and a high-cost firm.

2. A monopoly sells to consumers with inverse demand given by p(Q) = 100 - Q and technology T C(Q) = 5Q. Characterize the firm's profit-maximing behaviour when they are permitted to set a two-part tariff.
