Suppose that it costs $5 to produce a low-quality electric stapler and $30 to produce a high-quality stapler. Consumers cannot distinguish between good staplers and poor staplers when they make their purchases. There are four firms producing staplers. Consumers value staplers at their cost of production and are risk neutral. Will any of the four firms be able to produce high quality staplers without making losses? Suppose each firm produces 50 staplers. If one firm makes high-quality staplers, then each firm that produces low-quality staplers will earn profit of $ nothing and the firm that makes the high-quality staplers will earn $ nothing.
