In perfect market conditions (also called perfect competition) a firm is a price taker because other firms can enter the market easily and produce a product that is indistinguishable from every other firm’s product. This makes it impossible for any firm to set its own prices.
A price taker is a firm that cannot have any say in setting its own prices. A price taker simply has to accept the market price. This is in contrast to a price maker, which can have an influence over the price at which it sells its goods.
In perfect competition, there are two main reasons why a firm cannot get away with setting its prices above the market price. First, there is no difference between its product and that of every other firm in the market. Therefore, no one will pay extra for a firm’s product the way that they might pay extra for something like Nike shoes. Second, if a firm were to succeed in setting a higher price, more firms would enter the market, attracted by the higher profits that were available. This would increase supply and drive down the price of the firm’s product.
In perfect competition, firms sell homogeneous products and it is easy for a firm to enter the market. These two factors make it impossible for firms to set their prices above the market price. This makes them into price takers.
A Perfectly Competitive Market is one in which the number of sellers is large and all of them are producing homogeneous goods, and there is no price competition.
A price is set by the industry and each firm acts as a price taker, this happens because all firms are producing homogeneous goods due to which they cannot set different prices, because if a firm sets different prices the consumer will shift towards another firm.
