Oligopoly and marginal cost firms

If the cost of implementation is greater than the pay-off, clearly it will be rejected. For example, if an airline raises the price of its tickets from London to New York, rivals will not follow suit and the airline will lose revenue - the demand curve for the price increase is relatively elastic.

This is because competitors will generally ignore price increases, with the hope of gaining a larger market share as a result of now having comparatively lower prices. Bertrand model[edit] Main article: Bertrand competition The Bertrand model is essentially the Cournot-Nash model except the strategic variable is price rather than quantity.

Healthcare insurance in the United States consists of very few insurance companies controlling major market share in most states. Since price is above average total cost at that equilibrium output, all four firms will earn excess profits, although these profits are too small to permit entry of a fifth firm.

In other situations, competition between sellers in an oligopoly can be fierce, with relatively low prices and high production. Modeling[edit] There is no single model describing the operation of an oligopolistic market. At low prices, the firm faces the relatively inelastic market demand curve labeled MD 2.

Cost-plus pricing is also common in oligopoly markets because it is likely that the few firms that dominate may often share similar costs, as in the case of petrol retailers. Cournot competition The Cournot — Nash model is the simplest oligopoly model.

A price reduction may achieve strategic benefits, such as gaining market share, or deterring entry, but the danger is that rivals will simply reduce their prices in response. In a monopoly, there are no competitors to be concerned about.

Oligopolies tend to be both allocatively and productively inefficient. Strategic planning by oligopolists needs to take into account the likely responses of the other market participants. This situation is portrayed in Figure 2 below.

If one firm uses cost-plus pricing - perhaps the dominant firm with the greatest market share - others may follow-suit so that the strategy becomes a shared one, which acts as a pricing rule.

Market shares in an oligopoly are typically determined by product development and advertising. The reaction function shows how one firm reacts to the quantity choice of the other firm.

Additional sources of barriers to entry often result from government regulation favoring existing firms making it difficult for new firms to enter the market.

Revenue and Profit Maximization Under Oligopoly

Whether to compete with rivals, or collude with them. For example, an oligopoly considering a price reduction may wish to estimate the likelihood that competing firms would also lower their prices and possibly trigger a ruinous price war.

Another key feature of oligopolistic markets is that firms may attempt to collude, rather than compete. Corresponding to MD 1 is the marginal revenue curve labeled MR 1. Ability to set price Oligopolies are price setters rather than price takers.

The path to equilibrium is a series of actions and reactions. A primary example of such a cartel is OPEC which has a profound influence on the international price of oil. The two market demand curves intersect at point b. In a monopoly, there are no competitors to be concerned about.

Kinked-Demand Theory of Oligopoly

Oligopolists have to make critical strategic decisions, such as: All firms in a PC market are price takers, as current market selling price can be followed predictably to maximize short-term profits.Start studying Perfect completion, Monopoly, Oligopoly.

Oligopoly and Marginal Cost Firms

pressure from competing firms will force acceptance of the prevailing market price. what will the marginal cost equal for production at quantity (Q) level 4?

Topic 5: Oligopoly. The individual firms cost curves are also exactly the same as in the previous Topic. The socially efficient output occurs where the firm's marginal cost equals the price, at point e in the figure above.

costs: AC = MC = $1/unit. The two benchmarks are comeptitive price-taking and monopoly. We consider three oligopoly models below. 1.

Collusive Oligopoly in Economics (With Diagram)

They behave as competitive price takers, each setting price equal to marginal cost. Price PPC = $1/unit, total quantity Q = 9, and each produces y1 = y2 = units.

Since PPC = AC, their profits are zero:. OLIGOPOLY PROFIT The profit of firms in oligopoly is determined exactly in the same fashion as in other forms of markets: from optimum quantity where marginal revenue equals marginal cost, price is determined on the demand curve and unit cost on the average total cost curve.

However, this determination may be affected by the kinked. Classical economic theory assumes that a profit-maximizing producer with some market power (either due to oligopoly or monopolistic competition) will set marginal costs equal to marginal revenue. This idea can be envisioned graphically by the intersection of an upward-sloping marginal cost curve and a downward-sloping marginal revenue curve.
