Oligopolistic product mode

You are asked to identify a real world industry that conforms to either the Oligopolistic product model or the Monopolistically Competitive product model. Because these models are similar, you must provide detailed reasons why your real world industry conforms to the characteristics of the Oligopoly or Monopolistic Competition model. Additionally, you must provide a brief summary of implications for efficiency, equity, and public policy. As always, you will benefit and learn much from your fellow scholars' postings, so read and respond.
