These data imply Multiple Choice that market power is greatest in industry C. nothing about the degree of concentration across the three industries. that market power is greatest in industry A. that market power is greatest in industry B. Industries X and Y both have four-firm concentration ratios of 60 percent, but the Herfindahl index for X is 3,369, while that for Y is 2,412. These data suggest Multiple Choice that price competition is stronger in X than in Y. greater market power in X than in Y. that X is more technologically progressive than Y. greater market power in Y than in X.
