Why perfectly competitive firm is a price taker

Depending upon the competition and prices offered, a wheat farmer may choose to grow a different crop. Credit: modification of work by Daniel X. Growing a crop may be more difficult to start than a babysitting or lawn mowing service, but growers face the same fierce competition.

In the grand scale of world agriculture, farmers face competition from thousands of others because they sell an identical product. After all, winter wheat is winter wheat. But it is relatively easy for farmers to leave the marketplace for another crop.

In this case, they do not sell the family farm, they switch crops. In the intervening 15 or so years has the mix of crops changed? Since it is relatively easy to switch crops, did farmers change what was planted as the relative crop prices changed? All businesses face two realities: no one is required to buy their products, and even customers who might want those products may buy from other businesses instead.

Firms that operate in perfectly competitive markets face this reality. In this module you will learn how such firms make decisions about how much to produce, what price to charge, whether to stay in business or not, and many others. Industries differ from one another in terms of how many firms there are, how easy or difficult it is for a new firm to enter, and the type of products that are sold. This is referred to as the market structure of the industry.

In this module we focus on perfect competition. However, in other modules we will examine other market structures, including monopoly, oligopoly and monopolistic competition. Firms are said to be in perfect competition when the following conditions occur: 1 the industry has many firms and many customers; 2 all firms produce identical products; 3 sellers and buyers have all relevant information to make rational decisions about the product being bought and sold; and 4 firms can enter and leave the market without any restrictions—in other words, there is free entry and exit into and out of the market.

A perfectly competitive firm is called a price taker , because the pressure of competing firms forces them to accept the prevailing equilibrium price in the market. When a wheat grower wants to know what the going price of wheat is, he or she has to go to the computer or listen to the radio to check. The market price is determined solely by supply and demand in the entire market and not the individual farmer. If a firm in a perfectly competitive market raises the price of its product by so much as a penny, it will lose all of its sales to competitors, since no rational consumer would pay a higher price for an identical product.

In the real world, firms can have many fixed inputs. In the long run, perfectly competitive firms will react to profits by increasing production. They will respond to losses by reducing production or exiting the market. Ultimately, a long-run equilibrium will be attained when no new firms want to enter the market and existing firms do not want to leave the market, as economic profits have been driven down to zero.

A perfectly competitive firm is a price taker, which means that it must accept the equilibrium price at which it sells goods. If a perfectly competitive firm attempts to charge even a tiny amount more than the market price, it will be unable to make any sales. In a perfectly competitive market there are thousands of sellers, easy entry, and identical products. A short-run production period is when firms are producing with some fixed inputs.

Long-run equilibrium in a perfectly competitive industry occurs after all firms have entered and exited the industry and seller profits are driven to zero. Perfect competition means that there are many sellers, there is easy entry and exiting of firms, products are identical from one seller to another, and sellers are price takers.

If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent? Would independent trucking fit the characteristics of a perfectly competitive industry? Review Questions A single firm in a perfectly competitive market is relatively small compared to the rest of the market.

This means that if any individual firm charged a price slightly above market price, it would not sell any products.

In a perfectly competitive market, firms cannot decrease their product price without making a negative profit. Instead, assuming that the firm is a profit-maximizer, it will sell its goods at the market price.

Learning Objectives Describe degrees of competition in different market structures. Key Takeaways Key Points The major types of market structure include monopoly, monopolistic competition, oligopoly, and perfect competition.

Perfect competition is an industry structure in which there are many firms producing homogeneous products. None of the firms are large enough to influence the industry. The characteristics of a perfectly competitive market include insignificant contributions from the producers, homogenous products, perfect information about products, no transaction costs, and no long-term economic profits.

In practice, very few industries can be described as perfectly competitive, though agriculture comes close. Key Terms monopoly : A situation, by legal privilege or other agreement, in which solely one party company, cartel etc. Monopolistic competition : A market structure in which there is a large number of firms, each having a small proportion of the market share and slightly differentiated products.

Conditions of Perfect Competition A firm in a perfectly competitive market may generate a profit in the short-run, but in the long-run it will have economic profits of zero. Learning Objectives Calculate total revenue, average revenue, and marginal revenue for a firm in a perfectly competitive market. Key Takeaways Key Points A perfectly competitive market is characterized by many buyers and sellers, undifferentiated products, no transaction costs, no barriers to entry and exit, and perfect information about the price of a good.

The average revenue is calculated by dividing total revenue by quantity. Marginal revenue is calculated by dividing the change in total revenue by change in quantity. A firm in a competitive market tries to maximize profits. Economic profits will be zero in the long-run. In the short-run, if a firm has a negative economic profit, it should continue to operate if its price exceeds its average variable cost.

It should shut down if its price is below its average variable cost. Key Terms economic profit : The difference between the total revenue received by the firm from its sales and the total opportunity costs of all the resources used by the firm.
