The Characteristics Of Oligopolies

An oligopolistic market is one that has several dominant firms with the power to influence the market they are in; an example of this could be the supermarket industry which is dominated by several firms such as Tesco, Sainsbury’s, and Waitrose etc... Furthermore an oligopolistic market can be defined in terms of its structure and its conduct, which involve various different aspects of economics.

The definition of an oligopoly is the market condition in which the production of identical or similar products is done by a small number of big firms. Oligopolies can be categorized in to two types: homogenous oligopolies where the product is exactly the same (e.g.: steel production)

A monopoly is distinguished from a monopsony, in which there is only one buyer of a product or service; a monopoly may also have monopsony control of a sector of a market. Likewise, a monopoly should be distinguished from a cartel (a form of oligopoly), in which several providers act together to coordinate services, prices or sale of goods. Monopolies, monopsonies and oligopolies are all situations such that one or a few of the entities have market power and therefore interact with their customers (monopoly), suppliers (monopsony) and

An oligopoly is “a market situation in which relatively few sellers [like Burger King, McDonald’s] compete and high start-up costs form barriers to keep out new competitors [like Five Guys Burgers and Fries]” (Boone and Kurtz, 2012, p. 80). Within this competitive fast food burger industry, the main product being offered is a hamburger.

Oligopolies are a type of market structure evident in Australia, which is comprised of 2 or more firms having a significant share of the market. In an oligopoly the few firms sell similar but differentiated or homogenous products and is characterised by a large number of buyers making it a form of imperfect competition. This market structure is evident through the Big Four Banks, Phone Industry - Vodafone, Optus and Telstra.

· The knowledge of the nature of the elasticity of demand for products will help a business to decide whether to cut prices in a particular case.

Oligopolies have been around ever since there is trade. However, it has only recently gained grounds in this age of globalisation. Never before has oligopolistic competition been so fiercely contested across so many industries.

There are many models of market structure in the field of economics. They include perfect competition on one end, monopoly on the other end, and competitive monopoly and oligopoly somewhere in the middle. In this paper, we will focus on the oligopoly structure because it is one of the strongest influences in the United States market. Although oligopolies can also be global, we will focus strictly on the United States here. We will define oligopoly, give key characteristics important to the oligopoly structure, explain why oligopolies form, then give an example of an oligopoly in today’s economy. Finally, we will discuss the benefits and costs in this type of market structure.

Monopolistic competition and Oligopoly are considered imperfectly competitive markets that are a result of few to many firms offering differentiated products. Differentiation of products impede substitution, which allow producers to earn higher than normal profits and thereby enhance shareholder wealth (Byrd, J., Hickman, K., & McPherson, M., 2013). Oligopolies are highly interdependent, with actions of one firm will resulting in a reaction from another. The interdependence results in higher efficiency as a necessity to compete with rivals. According to Claessens "greater development, lower costs, enhanced efficiency and a greater and wider supply resulting from competition will lead to greater [financial] access (2009).

Elasticity of demand is a measure of responsiveness to a price change of a good or service. When demand is elastic, the percentage of a price change of a product will result in a larger percentage of quantity demanded (McConnell, p 77). It basically means reducing the price of a good service will result in a greater quantity demanded and an increase in revenue for the seller. When demand is inelastic, a change in price will result in a reduction of quantity demanded, which will then lead to a revenue decrease (McConnell, p 77). To demonstrate elastic and inelastic demand results, Company A sells 100 pens at $1.00 a piece each day, making their revenue $100.00. Company A

Cartel - firms ,especially dominant players, gather together to set up a price according to the profit maximisation in the whole market. In this case, firms act like a monopoly. The price of products of each firms is fixed, thus reduction of price competition will be achieved. Instead of pricing strategy, firms will compete each other over non-price competition, for example, advertising. Like monopoly, customers’ interest might be sacrificed because price is constructed according to the market’s profit maximisation point, whole industry can gain abnormal profit, which means customers pay more than they actually need to. According to the figure 1, price of products under cartel is set up at P because of profit maximisation E (MC=MR), and abnormal profit is PP2FG. However, cartel is illegal in many countries, including UK.

When facing an inelastic demand curve, a profit maximizing businessman would always raise price because increase in price will bring about increase in total revenue. On the other hand, when facing an elastic demand curve, he might or might not raise price because increase in price will bring about decrease in total revenue.

The oligopoly theory is based on the importance of the number of firms in an industry as well as on the nature of a product. In oligopoly, the more similar or homogenous product of different firms is, the greater is awareness of the competitors. In all oligopolistic markets several sellers represent a substantial proportion of total sales. The fewness of the firms is a key characteristic of oligopoly. As a result of the limited amount of companies in the oligopoly industry, the main problem is hidden in the recognition of mutual dependence or interdependence of companies (Lipczynski et al.,

“An observation made of oligopolistic business behaviour in which one company, usually the dominant competitor among

If the demand for the good or services of the company is elastic then the change in quantity demanded would be greater than a change in price. Let’s say the 10 percent decrease in price will cause increase in demand for 20 percent. The effect of this changes is that customers buying more products of this company. They are buying it for lower price but the price decrease outweigh by increasing quantity of the products or services. In this case the company benefits from these changes by raising profits. On the other hand, if company would raise the prices for the product the quantity will decrease so does the profit.
