An industry is composed of five firms. The sales in this market, from largest to smallest firm are $10, $5, $2, $2,$1. What is the industry's four-firm concentration ratio?
a) C4=1.00
b) C4=0.90
c) C4=0.85
d) C4=0.95
What is the industry's four-firm concentration ratio
=(10+5+2+2)/(10+5+2+2+1)
=0.95
the above will be answer

An industry is comprised of five firms. Sales of the four largest firms are $1,000,000, $500,000, $400,000, and $200,000. If the C4 ratio is 96 percent, then what is the HHI? 2,755. 3,046. None of the options. 1,810. 5,017.
An industry has five firms. Each of the four firms in the industry has a market share of 22 percent, and the last firm has a market share of 12 percent. Calculate the Herfindahl index and four-firm concentration ratio for the industry.
Industry A has four firms. The largest firm in Industry A has more than 90 percent of the market share. Industry B also has four firms, but each of those four firms in Industry B has 25 percent of the market share. The Herfindahl-Hirschman index will be A. larger for Industry B than Industry A, but the four-firm concentration will be the same. В. tte same for both industries, but the four-firm concentration will be larger for industry Y than Industry A C....
