1. Few sellers.

You are watching: Which cannot be a characteristic of an oligopolistic industry

Tright here are simply numerous sellers that manage all or the majority of of the sales in the sector.

2. Barriers to enattempt.It is hard to enter an oligopoly industry and contend as a little start-up company. Oligopoly firms are huge and also benefit from economic situations of scale. It takes significant know-exactly how and also funding to compete in this sector.

3. Interdependence.Oligopoly firms are huge family member to the industry in which they run. If one oligopoly firm alters its price or its marketing strategy, it will certainly significantly impact the rival firm(s). For instance, if Pepsi lowers its price by 20 cents per bottle, Coke will be impacted. If Coke does not respond, it will shed substantial market share. As such, Coke will certainly the majority of likely reduced its price, as well.

4. Prevalent advertising.Oligopoly firms generally advertise on a nationwide range. Many Super Bowl, World Series, Wimbledon finals, World Cup finals, NBA finals, and NCAA March Madness advertisements are sponsored by oligopoly firms.

Instances of Oligopoly Industries

The following are examples of oligopoly industries:The vehicle industryThe steel industryThe photographic devices industryThe aircraft production industryThe beer (wholesale) industryThe cereal (breakfast) industryInfant formula makersThe oil market (wholesale)The airline industryThe beverage (consisting of soft drinks) industry



Profit Maximization in an Oligopoly Industry

Firms in oligopoly industries maximize earnings in the same means as firms in various other industries. They maximize profits at the amount wright here a climbing marginal price equals or ideologies marginal revenue, as long as the price is greater than the average variable cost (otherwise, shut down).

The Kinked Demand Curve

Some economists claim that because of the interdependence in between rival oligopoly firms, tbelow are two demand also curves to take into consideration.

Let’s intend that the present price of a product marketed by oligopoly firm X is $8, and also the firm sells 5 products at this price. What will certainly happen to the firm’s amount marketed if it changes its price? The answer relies on what rival firm Y will perform in response to the price readjust.

Let’s assume that firm Y does not copy the price adjust of firm X. Then if firm X lowers its price, it will certainly have actually a significant competitive advantage over firm Y, and also its amount sold will certainly boost substantially. If it raises its price, the opposite will certainly happen. Therefore, firm X’s price elasticity of demand is high, if firm Y does not copy its price readjust. This is presented in Table 1 below, and is shown by demand also curve D1 in the graph listed below.

Let’s now assume that firm Y does copy the price readjust of firm X. Then if firm X lowers its price, it will certainly not have actually a far-reaching competitive benefit over firm Y, and also its amount marketed will not rise substantially (there is no substitution effect, just an revenue effect). If it raises its price, and also firm Y duplicates the price adjust, then firm X will not lose a lot market share. In various other words, firm X’s price elasticity of demand also is low, if firm Y does copy its price adjust. This is shown in Table 2 listed below, and also is portrayed by demand also curve D2 in the graph listed below.

Some economists believe that rival firm Y will certainly copy a price readjust of firm X, just if firm X lowers its price. However, they believe that rival firm Y will certainly not copy a price adjust of firm X, if firm X raises its price. Hence, if firm X lowers its price listed below the present price of $8, demand D2 is relevant. This is shown by the green part of Table 2 and the green part of demand curve D2. If firm X raises its price above the present price of $8, demand also curve D1 is relevant. This is depicted by the green component of Table 1 and also the green component of demand curve D1. We end up through two demand also curves, relying on whether firm X lowers or raises its price. Because of this, the demand curve of firm X is kinked. This is depicted by the green kinked demand curve in the graph below.


Since the demand curve is kinked, tright here is a gap in firm X’s marginal revenue curve. As you can watch from the calculations in the tables over, marginal revenue at amount 5 is various relying on whether you usage demand 1 or demand also 2. The pertinent marginal revenue sections of the kinked demand curve are illustrated by the blue curve over.

Not eincredibly economist believes in the kinked demand also curve theory. Some financial experts think that oligopolies behave simply favor various other firms. In that case, the demand also and also revenue curves look comparable to the demand also and revenue curves of the monopoly and also monopolistically competitive firms disputed prior to.

Profits of Firms in an Oligopoly Industry

Regardless of the shape of the demand curve, we deserve to conclude that for oligopoly firms, economic (above-normal) earnings are feasible in the long run bereason of the more difficult enattempt into the sector. However, in the lengthy run, exceptionally high revenues are unmost likely. If the price of the product is too high, rivals will enter eventually, undercut the existing firms’ prices, and reduced sector earnings. Occasionally, gasoline prices increase, and also civilization are came to that oil providers are exploiting consumers. Not to say that this never before happens, however the higher gasoline prices are usually a result of higher demand (for example, during the summer) or lower supply (because of delibeprice cutbacks by OPEC, or a crisis in an oil-creating country). If oil prices are extreme for a substantial duration of time, then, despite barriers, new innovations will be arisen (as we have actually seen via fracking) and new rivals will enter the market. This will increase the supply and also reduced the price. If prices are high, consumers may likewise respond by reducing demand (purchasing even more hybrid or fuel-efficient cars, turning to different resources of power, living closer to work). These market pressures will certainly in the lengthy run, make prices come down.
