Suppose that the most popular car dealer in your area sells 10 percent of all vehicles. If all other car dealers sell either the same number of vehicles or fewer, what is the largest value that the Herfindahl index could possibly take for car dealers in your area? In that same situation, what would the four-firm concentration ratio be?
Suppose that the top six firms in an industry have total annual sales of $250 billion, $210 billion, $150 billion, $120 billion, $80 billion,
and $60 billion, respectively.
Instructions: Round your answers to the nearest whole number.
a. What is the four-firm concentration ratio for this industry?
percent
b. What is the Herfindahl index for this industry? (Hint: To find the Herfindahl index, you will need to compute the percentage market
share for each firm in the industry. When calculating market share, do not round your intermediate calculations.)
