Choose ONE of the following industries: (1) Wireless (e.g., Sprint); (2) Automobile (e.g., Ford); or (3) Airlines (e.g., United) that are in an oligopolistic market structure, and then:

a.Research each of the firms in the industry to determine their market shares (i.e., % sales) - list each in your paper.

b. Compute the concentration ratio (CR)and the HHI (show your work in your post) - the reference to do this is page 252 in the text. Note: To determine the four-firm CR, just add the % market share of the four largest firms. Also, when squaring market share for the HHI do not convert sales % to decimal but square the actual % sales number.

c. What do the CR and HHI indicate about the industry?
