In January, the biggest names in the business rolled out heavily discounted menus across the US making their fast food even cheaper — less expensive than a loaf of bread or a carton of juice. Rivals were quick to follow suit. The answer is scale; sales of burgers or chicken dippers or fries — in huge numbers.
Oligopolies are price setters rather than price takers. Additional sources of barriers to entry often result from government regulation favoring existing firms making it difficult for new firms to enter the market. High barriers of entry prevent sideline firms from entering market to capture excess profits.
Product differentiation Product may be homogeneous steel or differentiated automobiles. Oligopolies have perfect knowledge of their own cost and demand functions but their inter-firm information may be incomplete.
Buyers have only imperfect knowledge as to price,  cost and product quality. Interdependence The distinctive feature of an oligopoly is interdependence. Each firm is so large that its actions affect market conditions.
Therefore, the competing firms will be aware of a firm's market actions and will respond appropriately. This means that in contemplating a market action, a firm must take into consideration the possible reactions of all competing firms and the firm's countermoves.
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. Or if the firm is considering a price increase, it may want to know whether other firms will also increase prices or hold existing prices constant.
This anticipation leads to price rigidity as firms will be only be willing to adjust their prices and quantity of output in accordance with a Tesco price elasticity of demand leader" in the market.
This high degree of interdependence and need to be aware of what other firms are doing or might do is to be contrasted with lack of interdependence in other market structures.
In a perfectly competitive PC market there is zero interdependence because no firm is large enough to affect market price.
All firms in a PC market are price takers, as current market selling price can be followed predictably to maximize short-term profits. In a monopoly, there are no competitors to be concerned about.
In a monopolistically-competitive market, each firm's effects on market conditions is so negligible as to be safely ignored by competitors. Non-Price Competition Oligopolies tend to compete on terms other than price.
Loyalty schemes, advertisement, and product differentiation are all examples of non-price competition. Oligopolies in countries with competition laws[ edit ] Oligopolies become "mature" when they realise they can profit maximise through joint profit maximising.
As a result of operating in countries with enforced competition laws, the Oligopolists will operate under tacit collusion, which is collusion through an understanding that if all the competitors in the market raise their prices, then collectively all the competitors can achieve economic profits close to a monopolist, without evidence of breaching government market regulations.
Hence, the kinked demand curve for a joint profit maximising Oligopoly industry can model the behaviours of oligopolists pricing decisions other than that of the price leader the price leader being the firm that all other firms follow in terms of pricing decisions. As the joint profit maximising achieves greater economic profits for all the firms, there is an incentive for an individual firm to "cheat" by expanding output to gain greater market share and profit.
In Oligopolist cheating, and the incumbent firm discovering this breach in collusion, the other firms in the market will retaliate by matching or dropping prices lower than the original drop. Hence, the market share that the firm that dropped the price gained, will have that gain minimised or eliminated.
This is why on the kinked demand curve model the lower segment of the demand curve is inelastic. As a result, price rigidity prevails in such markets. Modeling[ edit ] 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 considering certain circumstances. Some of the better-known models are the dominant firm modelthe Cournot—Nash modelthe Bertrand model and the kinked demand model.
Cournot competition The Cournot — Nash model is the simplest oligopoly model. The model assumes that there 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 reacts 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 is 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. The marginal revenue function is R.Oligopoly Defining and measuring oligopoly. An oligopoly is a market structure in which a few firms dominate.
When a market is shared between a few firms, it is said to be highly concentrated. What are the main conditions necessary for price discrimination to work?
Here are the main conditions required for discriminatory pricing: Differences in price elasticity of demand: There must be a different price elasticity of demand for each group of alphabetnyc.com firm is then able to charge a higher price to the group with a more price inelastic demand and a lower price to the group with a.
Tesco Group Business 3 rd Largest grocery retailer in the World. group sales in excess of £62 billion 14 countries Over stores Worldwide. In an oligopoly, firms operate under imperfect alphabetnyc.com the fierce price competitiveness created by this sticky-upward demand curve, firms use non-price competition in order to accrue greater revenue and market share.
"Kinked" demand curves are similar to traditional demand curves, as they are downward-sloping. In the case of McDonald’s, Credit Suisse estimates that the company’s foot traffic in the US fell around 11% from to so the January drop in prices could be a further attempt to.
This will depend on the price elasticity of demand. Videos and podcasts. Scotland first country to introduce minimum alcohol price Channel 4 News, Fatima Manji (15/11/17) made Tesco particularly keen to prevent price rises.
