When companies in the oligopolistic industries announce a proposed merger, it is often met with resistance from antitrust authorities (such as Federal Trade Commission (FTC) and Department of Justice (DOJ) in U.S.). In U.S., we have seen recent examples in the cell phone service provider industry, airline industry, and beer industry. Identify and share an example of a recent merger that was investigated by antitrust authorities. Provide an overview of the merger and discuss why the merger was either allowed to proceed or was blocked. Discuss what were the deciding factors? If the merger review is still pending, explain what you think the major decision factors will be and whether you expect the merger to be approved or blocked.
