Chapter (14)
Firms in Competitive Markets
In this chapter, we will discuss the general characteristics of a perfectly competitive
market, and the operations of a perfectly competitive firm.
In any economy, there exists a number of market structures, these are:
1. Perfectly competitive market.
2. Monopoly
3. Oligopoly
4. Monopolistic competitive market.
In the chapter, we will discuss the perfectly competitive market, whereas the following 3
chapters will introduce to us the other market structures.
One major difference between perfectly competitive market and all other markets is that
all these markets (other than the perfectly competitive market) are considered imperfectly
competitive markets.
What do perfectly and imperfectly competitive markets mean?
We will start first by listing the major characteristics of a perfectly competitive market.
Characteristics of a perfectly competitive market:
1. Many small sellers that no producer can affect the market price of the product.
2. Many small consumers that no consumer can affect the market price of the product.
3. Homogeneous or standard product supplied by all producers.
4. Any firm operating in this market is a price taker, where firms in this market produce
and sell at the given market price.
5. Barriers to entry to this market are very low and even nonexistent. Hence firms can
enter and leave the industry freely.
From the above characteristics, we can conclude the following definition of a perfectly
competitive market:
A perfectly competitive market is a market where any firm has no control on
determining the price of its product. In other words, it is the market forces (that is
forces of DD and SS) that determines the price of perfectly competitive firms’ products,
and the firms operating in this market accept these market ‘prices; hence we call perfectly
competitive firms as price-takers that is taking the price of their products from the market
and having no control on setting or determining the price of their products.
When a firm has no control on setting the price of its product, its DD curve is a
completely horizontal curve.
On the other side, imperfectly competitive market is a market where the operating firms
have some degree of control on setting the price of their products. The degree of control
determines the degree of imperfection existing in this market. Sine an imperfectly
competitive firm controls the price of its product, then its DD curve is a downward-
sloping curve.
In economics, we identify 3 major imperfectly competitive markets:
1. Monopoly
2. Oligopoly
3. Monopolistic Competitive Market
Objectives, Important Decisions: and Operations of a Perfectly Competitive Firm
To understand the operations of a perfectly competitive firm, we need to recall some
algebraic theorems to understand the below analysis.

Conditions for Company Equilibrium
To achieve Equilibrium, a Company must meet two conditions:
You need to make sure that the marginal revenue is equal to the marginal cost (MR = MC).
If MR> MC, the Company has an incentive to expand production and sell additional units.
If MR<MC, the Company needs to reduce production because additional units generate more costs than revenue.
Only when MR = MC does the Company achieve maximum profit.
Chapter 13A monopolistically competitive market is characterized.docxketurahhazelhurst
Chapter 13
A monopolistically competitive market is characterized by:
· many buyers and sellers,
· differentiated products, and
· easy entry and exit.
The monopolistically competitive market is similar to perfect competition in that there are many buyers and sellers who can enter or leave the market easily in response to economic profits or losses. A monopolistically competitive firm, though, is similar to a monopoly in that it produces a product that is different from that produced by all other firms in the market. The restaurant market in New York City provides a good example of a monopolistically competitive market. Each restaurant has its own recipes, decor, ambiance, etc. but also must compete with many other similar restaurants.
Because each firm produces a differentiated product, it won't lose all of its customers if it raises its prices. Thus, a monopolistically competitive firm faces a downward sloping demand curve for its product. As noted in Chapters 8 and 10, whenever a firm faces a downward sloping demand curve, its marginal revenue curve lies below its demand curve. The diagram below illustrates the relationship that exists between a monopolistically competitive firm's demand and marginal revenue curves.
While the diagram above seems similar to the demand and marginal revenue curves facing a monopolist, there is a critical difference. In a monopolistically competitive market, the number of firms changes as firms enter or leave the industry. When new firms enter the market, the customers are spread over a larger number of firms and the demand for each firm's product declines. An increase in the number of firms also tends to result in an increase in the elasticity of demand for each firm's products (since demand is more elastic when more substitutes are available). The diagram below illustrates the shift in a typical firm's demand curve that occurs when additional firms enter a monopolistically competitive market.
Short-run and long-run equilibrium in monopolistically competitive markets
Let's examine the determination of short-run equilibrium in a monopolistically competitive output market.
The diagram below illustrates a possible short-run equilibrium for a typical firm in a monopolistically competitive market. As with any profit-maximizing firm, a monopolistically competitive firm maximizes its profits by producing at a level of output at which MR = MC. In the diagram below, this occurs at an output level of Qo. The price is determined by the amount that customers are willing to pay to buy Qo units of output. In the example below, the demand curve indicates that a price of Po will be charged when Qo units of output are sold.
In a monopoly industry, economics profits could persist indefinitely due to the existence of barriers to entry. In a monopolistically competitive industry, however, the existence of economic profits results in the entry of additional firms into the industry. As additional firms enter, the demand for each ...

1. Firms in Perfect Competition A Simplified Market Mankiw Chapter 14
2. Basic Characteristics There are many buyers and many sellers in the market. The goods offered by the various sellers are largely the same. Firms can freely enter and exit the market. Definition: a market with many buyers and sellers trading identical products so that each buyer and seller is a price taker.
3. Competitive Firm The Competitive Firm has an internal supply curve (MC), to determine what quantity to produce at a specific price. The supply and demand of the overall market determine the price.
4. Competitive Market + + + + = All of the individual firms’ supply curves add to form the Market Supply The Market Demand is determined by consumers.
5. Firm Supply & Demand Within the firm, the MC curve acts as supply and MR acts as demand. We can get the MR curve from MR = AR = P MR = (∆ Q x P)/∆ Q = P AR = (Q x P)/Q = P
6. Profit Maximization (Graphically) Profit Max Each firm reflects the competitive market it is part of: Focuses on MC (firm supply) and MR (firm demand) Profit Max occurs at MR = MC; “equilibrium point” At this point, the cost of an additional item exceeds the revenue for producing it. Firm Demand (MR) is perfectly inelastic.
7. Finding Profit (Graphically) Profit Max Total Profit Total Profit = Total Revenue – Total Costs Total Costs = ATC x Q Total Revenue = Price x Q Total Profit = (P – ATC) x Q
9. Long Run v. Short Run Short Run – Firms make decisions at the current time. Variable Costs can be changed. (ie. more staff, more field hands, using more energy for machinery) Fixed Costs are fixed. (ie. planting more seeds, factory building rent) Long Run – Firms make decisions over time. Variable Costs are still variable. Fixed Costs can also change. (ie. rent a 2nd factory building)
10. The Decision to Shut Down or Exit Shut Down – Closing down for the day. Occurs in the short run. When a firm determines that it cannot cover its variable costs, it decides to not ‘produce’ until conditions change. Even if a firm is not making a profit (P is below the ATC), it can defer the fixed costs. However, if it cannot cover the variable costs, the total deficit is greater when producing.
11. The Decision to Shut Down or Exit Exit – Leaving the market for and indefinite time. Occurs in the long run. When a firm takes losses in the long run, it decides to leave the market – no incentive to stay. This results in other firms taking less losses – 0 long run profit.
12. Long Run Profit Because firms can enter and exit, they will enter until the total market profit is 0. If firms are making a profit, other firms will also want to make profit; however, this will shift supply right and lower price. If firms have a consistent loss, some will leave the market until all other firms make 0 profit.
