Do some research and write a Topic Paper that describes the market structure in which a typical professional sports team in or outside the United States (e.g. New York Yankees, Kansas City Wizards, New Jersey Nets, Manchester United, etc.) operates. Do they cleanly fit into one of the four structures discussed in our book? If yes, describe which one and support the conclusion you reached? If you believe they do not fit neatly into a structure, describe why not?
