Interdependence, Conjectural Variation, Independent Action And Collusion To Our Understanding Of Oligopoly Theory

Oligopolistic markets, such as supermarkets or car manufacturing, can be defined in terms of market structure or in terms of market conduct.

The Aerospace and Defense (A&D) is a highly concentrated industry (Global Edge, n. d.). The market is largely dominated by a small number of large companies in the industry, which is a characteristic of an oligopolistic competition. The major players in the industry include Boeing, Lockheed Martin, General Dynamics, Northrop Grumman, and Raytheon, (Choi, 2016). In oligopolistic market, companies make decisions based on their own actions as well as of others’ in mind (Johnson, 2014; Boundless, 2017). According Pettinger (2016), the key characteristics of oligopoly are

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.

2. (Price Leadership) why might a price–leadership model of oligopoly not be an effective means of collusion in an oligopoly?

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).

An Oligopoly refers to a market structure where-by the suppliers have formed some form of cartel and are acting in unison. In such a case the suppliers have the power to determine the price of the commodity and may set any price.

When companies are making decisions, the companies do not worry about how the rivals will react, in part to each company’s actions are unlikely to affect its rivals to a great extent hence they are independent. In addition, there is perfect knowledge in the market hence new companies have the freedom to enter into the industry. The companies are also profit maximizers, producing output where marginal revenue equals marginal cost; the profit maximising condition. Companies in a

What is a monopoly? According to Webster's dictionary, a monopoly is "the exclusive control of a commodity or service in a given market.” Such power in the hands of a few is harmful to the public and individuals because it minimizes, if not eliminates normal competition in a given market and creates undesirable price controls. This, in turn, undermines individual enterprise and causes markets to crumble. In this paper, we will present several aspects of monopolies, including unfair competition, price control, and horizontal, vertical, and conglomerate mergers.

•Monopolistic competition- When an industry contains many rival firms, each of which has a comparable but at least slightly different product. Restaurants, are an example, all serve food but of different types of food and in different sites. Manufacture costs are above what could be attained if firms sold equal products, but consumers have an advantage from the variety.

Has the economy ever thought about direct impact from monopoly and oligopoly industries? The structure of a monopoly based industry exemplifies one seller in the entire market. On the other hand, the concept of an oligopoly industry illustrates few sellers that have the potential of making a direct impact in one single industry idea. The economy has depended on the market share of a monopoly and an oligopoly trade. However, a monopoly industry differs from an oligopoly industry due to a monopoly competitor dominates a majority of the market share of many industries and an oligopoly competitor contains few sellers who dominate a market share based on one single industry idea.

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

Barriers to entry and exit are also likely to exist. In oligopoly markets there is product differentiation, the extent of which depends on the type of product produced. This leads to interdependency, as the actions of one large firm will directly affect another large firm. Therefore, firms are said to be operating under conditions of
