Quizplus · Accepted Answer

In a perfectly competitive industry, there are numerous competitors producing the same product and charging the market price. If one firm were to charge a higher price than the market-clearing price, no consumers would buy from that firm and instead buy from the other firms offering the same product at the market price. Therefore, firms cannot charge a price above the market-clearing price without losing all their customers.
