The MegaTek Corporation’s vice president of marketing made the following statement to the company’s board of directors:
MegaTek has been losing market share to UltraCorp for three years straight. Customer surveys suggest that consumers perceive UltraCorp products to be of higher quality than those produced by MegaTek. MegaTek spends more annually on research and development than UltraCorp does, and it pays its employees a higher average salary, so we do not believe that our products are actually inferior; rather, the perception is due to the fact that UltraCorp charges higher prices and spends more money on advertising. In order to regain the lost market share from UltraCorp, MegaTek should raise its prices and devote more money to advertising.
