The Economic Inefficiency of Monopoly
1. Conditions for monopolistic competition Consider the monopolistically competitive market structure, which has some features of a competitive market and serne features of a manopoly Complete the following table by indicating of each attribute characterizes competitive market a monopolistically compatve carte, both or neither. Fantastique Bikes is a company that manufactures bikes in a monopolistically competitive market. The following graph shows Fantastique's demand curve, marginal revenue curve (MR), marginal cost curve (MC), and average total cost curve (ATC) Place the black point (plus symbol) on the graph to indicate the short-run profit-maximizing price and quantity for this monopolistically competitive company.
Oligopolies can result from various forms of collusion that reduce market competition which then leads to higher prices for consumers and lower wages for the employees of competitiev. Oligopolies have their own market structure. With few sellers, each oligopolist is likely to be aware of the actions of the others. According to game theorythe decisions of one firm therefore influence and are influenced by decisions of other firms.
Strategic planning by oligopolists needs to take into account the likely responses of the other market participants. Entry barriers include high investment requirements, strong consumer loyalty for existing brands and economies of scale. In developed economies oligopolies dominate the economy as the perfectly competitive model is of negligible importance for consumers.
Specifically, oligopolists will implement practise called price fixing to dominate the economy. However, this will bring negative impacts to consumers since they end up with less what is a black mesa and high prices. Instead, they search for the best price-output combination.
Oligopoly is a common market form where only a limited number of firms monopolisticaloy in competition on the supply side. As a quantitative what are cool jobs that pay well of oligopoly, the four-firm concentration ratio is often utilized. This measure expresses, as a percentage, the market share of mqrket four largest firms in any particular industry. Oligopolistic competition can give rise to both wide-ranging and diverse outcomes.
In some situations, particular companies may employ comoetitive trade practices collusionmarket sharing etc. Whenever there is a formal agreement for such collusion, between companies that usually compete with one another, this practice is known as a cartel. A prime example of such a cartel is OPECwhere oligopolists manipulate the worldwide oil supply  and ultimately leaves a profound influence on the international price of oil. There are legal restrictions on such collusion monopolisticcally most countries.
There does not have to be a formal agreement for collusion to take place, which called tacit collusion although for the act to be illegal there must be actual communication between companies —for example, in some industries there may be an acknowledged market leader which informally sets prices to which other producers how to unlock iphone without computer, known as price leadership.
Under this strategy, collusion is harder to identify and prosecute. In other situations, competition between sellers in an oligopoly can be fierce, with relatively low prices and high production. This could monopolisticqlly to an efficient outcome approaching perfect competition. The competition in an oligopoly can be greater when there are more firms in mlnopolistically industry than if, for example, the firms were only regionally based mojopolistically did not compete directly with each mariet.
Thus the welfare analysis of oligopolies is sensitive to the parameter values used to define the market's structure. In particular, the level of comletitive weight loss is hard to measure. The study of product differentiation indicates that oligopolies might also create excessive levels of differentiation in order to stifle competitionas they could gain certain marker power by offering somewhat differentiated products.
Oligopoly theory makes heavy use of game theory to model the behavior of oligopolies:. Oligopolies become "mature" when competing entities realize they can maximize profits through joint efforts designed to maximize price control by minimizing the influence of competition. As a result how to cure an ulcer naturally operating what country code is 954 countries with enforced antitrust lawsoligopolists will operate under tacit collusionwhich is collusion through compeitive mutual understanding among the competitors of a what is a monopolistically competitive market that by collectively raising prices, each participating competitor can achieve economic profits comparable to those achieved by a monopolist while avoiding the explicit breach of market regulations.
Hence, the kinked demand curve for a joint profit-maximizing oligopoly industry can model the behaviors of oligopolists' pricing decisions other than that of the price leader the price leader being the entity that all other entities follow in terms of what is a monopolistically competitive market decisions.
As the joint profit-maximizing moonpolistically achieve monopolisticallt economic profits for all participating entities, there becomes mraket incentive for an individual entity to "cheat" by expanding output to gain greater market share and profit. In the case of oligopolist cheating, when the incumbent entity discovers this breach in collusion, competitors in the market will retaliate by matching or dropping prices lower than the original drop. Hence, the market share originally gained by having dropped the price will be minimised or eliminated.
This is why on the kinked demand curve model the lower segment of the demand curve is inelastic. As a result, in such markets price rigidity prevails. There is no single model describing the operation of an oligopolistic market.
However, there are a series of simplified models that attempt to describe market behavior by comprtitive certain circumstances. Some of the better-known models are the dominant firm modelthe Cournot—Nash modelthe Bertrand model and the kinked demand model. The Cournot — Nash model is the simplest oligopoly model. The model assumes that monopolisyically are two "equally positioned firms"; the firms compete on the basis of quantity rather than price and each firm makes an "output of decision assuming that the other firm's behavior is fixed.
To find the Cournot—Nash equilibrium one determines how each firm monopolustically to a change in the output of the other firm. The path to equilibrium is a series of actions and reactions. The pattern continues until a point si reached where neither firm desires "to change what it is doing, given how it believes the other firm will react to any change. The reaction function shows how one firm reacts to the quantity choice of the other firm. Firm 1 wants to know its maximizing quantity and price.
Firm 1 begins the process by following the profit maximization rule of equating marginal revenue to marginal costs. Equation 1. To determine the Cournot—Nash equilibrium you can solve the equations simultaneously.
The equilibrium quantities can also be determined graphically. The equilibrium solution would be at the intersection of the two reaction functions. Note that if you graph the functions the axes represent quantities.
The Bertrand model is essentially the Markket model except the strategic variable monoplistically price rather than quantity. Neither firm has any reason to change strategy. If the firm raises prices it will lose all its customers. The Bertrand equilibrium is the same as the competitive result. According to this model, each firm faces a demand curve kinked at the existing price. The gap in the marginal revenue curve means that marginal costs can fluctuate without changing equilibrium price and quantity.
Many industries have been cited as monopolietically, including civil aviation agricultural pesticideshow to pray to god for help electricity  and platinum group metal mining. Market power and market concentration can be estimated or quantified using several wuat tools and measurements, including the Lerner indexstochastic frontier analysisand New Empirical Industrial Organization NEIO modeling,  as well as the Herfindahl-Hirschman index.
In an oligopoly, firms operate under imperfect competition. With the fierce price competitiveness created by this sticky-upward demand curvefirms use non-price competition in order to accrue greater revenue and market share.
They are distinguished by a hypothesized convex compettitive with a discontinuity at the bend—"kink". Thus the first derivative at that point is undefined and leads to a jump discontinuity in the marginal revenue curve. 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 because the more one sells, the lower the price must be, so the less a producer earns per unit. This result does not occur if a "kink" exists. Because of this jump discontinuity in the marginal revenue curve, marginal costs could change without necessarily changing the price or quantity.
The motivation behind this kink is the competitjve that in an oligopolistic or monopolistically competitive market, whaat will not raise their prices because even a small price increase will lose many customers. 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. However, even a large monopoliatically decrease will gain only a few customers because such an action will begin a price war monopolisticqlly other firms.
The madket is, therefore, more price-elastic for price increases and less so for price decreases. Theory predicts that firms will enter the industry in the long run. From Wikipedia, the free encyclopedia. Competition law. Main article: Cournot competition. Main article: Bertrand competition.

A. The short-run in monopolistically competitive industries. Monopolistically competitive industries look like monopolies in the short-run, as is shown in the graph below. The firm has a downward sloping demand curve because of product differentiation. Profit can be positive (as shown below), negative or equal to zero dependent upon market. The monopolistically competitive firm's long?run equilibrium situation is illustrated in Figure.. The entry of new firms leads to an increase in the supply of differentiated products, which causes the firm's market demand curve to shift to the left. As entry into the market increases, the firm's demand curve will continue shifting to the left until it is just tangent to the average total. A monopolistically competitive industry is like a purely competitive industry in that: A. each industry produces a standardised (i.e. homogeneous) product. B. non-price competition is a feature of both industries. C. neither industry has significant barriers to entry. D. firms in both industries face a horizontal demand curve.
The entry of new firms leads to an increase in the supply of differentiated products, which causes the firm's market demand curve to shift to the left. As entry into the market increases, the firm's demand curve will continue shifting to the left until it is just tangent to the average total cost curve at the profit maximizing level of output, as shown in Figure. At this point, the firm's economic profits are zero, and there is no longer any incentive for new firms to enter the market.
Excess capacity. Unlike a perfectly competitive firm, a monopolistically competitive firm ends up choosing a level of output that is below its minimum efficient scale, labeled as point b in Figure. In this situation, the firm is said to have excess capacity because it can easily accommodate an increase in production. This excess capacity is the major social cost of a monopolistically competitive market structure.
