A competitive firm is small, relative to the market in which it operates. Therefore, it has no power to influence the price of its output. It takes the price as given by market conditions. Competitive firms are price-takers. They can sell as much or as little as they want at this price. Thus, the competitive firm faces a horizontal demand curve. Because a competitive firm sells a product with many perfect substitutes (the product of all the other firms in its market), the demand curve that any one firm faces is perfectly elastic.
