This dissertation consists of three essays on antitrust issues. In the first paper, I propose two models based on quantity setting game to analyze the profitability of merger, its welfare effect and price effect. In the second paper, I deal with the issue how uncertainty on other firms' discount rates affects the competitive behavior in oligopoly market. In the third paper, I analyze two antitrust policy issues for effective cartel deterrence: leniency program and crackdown policy.
