One of the characteristics of competitive market is that the firm is a price taker

Sellers in perfectly competitive markets are price takers. A price taker is a seller who does not have the power to determine the price to charge his or her prices but he or she takes the price to provide by the market forces. These happen where the commodities sold in the market are homogenous or similar thus there is uniformity in prices and any seller who attempts to sell a different price, he or she makes losses since buyers shift to other commodities. A price maker, on the other hand, refers to a seller who has the market power to determine the amount to charge his or her commodity. A price maker mostly exists in monopoly markets since he or she is the only person who sells the commodity thus he or she determines the amount of revenue he or she wants to make.

A Price maker makes more revenue since he determines the amount to charge for his commodities, unlike a price taker who earns normal profits since prices for his commodities are determined by market forces.
