Oogle or Comcast Antitrust Investigation (See Instructions Below)

I need an essay that addresses a recent case of an antitrust investigation. You can use the Google or Comcast antitrust investigation. These questions must be answered in the paper and key terms listed below must be used in the paper:

1. Why was/were the firm(s) investigated for antitrust behavior?
2. Identify some of the costs (pecuniary and nonpecuniary) associated with the antitrust behavior (firms having power in the market). Additionally, note the specific antitrust act (Sherman Act, Clayton Act, etc.) under which the violation was investigated.
3. Given your research and findings, are monopolies and oligopolies (firms demonstrating power) always bad for society? Be sure to provide real world examples of where this may be the case to strengthen your position.
4. Provide at least one example of a case where having a monopoly or oligopoly may actually benefit the society.

Key concepts to include in your paper include the following.

i??Monopoly Market Structure
i??Oligopoly Market Structure
i??Barriers to Entry Into the Market
i??Natural Monopoly
i??Government Monopoly
i??Downward Sloping Demand Curve
i??Economies of Scale
