Economics Coursework: Oligopolistic Market Structures

The Question…

How can small independent retailers compete in an oligopoly?

In this investigation, I will determine if small retailers can compete in an oligopolistic market structure. But before this question can be answered, the term “oligopoly” must first be defined as so to compare the market structure of an oligopoly to the structure of the supermarket industry. There are some main factors that an oligopolistic market possesses; all of them must be fulfilled to classify a market as an oligopoly.

However, my take on why small retailers continue to survive in oligopolistic market structures due to how they provide a sense of unity within the area they encompass; providing goods that they know that community needs, based heavily on the fact that the small retailer sees a local connection in the area which can be capitalised on by being more personal and closer to the community they reside in. It’s an intangible factor in which small retailers can reside in and use to take

Factors that an oligopoly must have:

  1. Concentration Ratio: In many different markets across the world, the concentration ratio of a specialist market is used to analyse the size of a specific firm within that market. In a monopoly; owning a firm with a concentration ratio over 95% would mean that firm would be considered as creating a monopoly in that market. However, an oligopoly has different criteria which analyses the “Big 4” firms in a market. If the relative size of those firms add up to a percentage above 75% (in the supermarket industry); then that market with the “Big 4” can be considered to be an oligopolistic market. For the UK Supermarket Market; the information group TNS Superpanel records the relative size of grocery markets. Their most recent records show the following about the top 4 supermarkets in the UK today. The results below indicate that the concentration ratio is in line for an oligopolistic market structure:

Tesco: 31.6%

ASDA: 16.6%

Sainsbury’s: 16.0%

Morrisons: 11.0%

Total for all: 75.2%

  1. Non-Priced Competition: This is a marketing technique which involves using the quality, popularity or any other aspect of a product that is not price to attract more consumers to purchase that product. In an oligopoly, price is not used as a means to compete with other firms; as soon as one firm raises their price for a product, that firm will lose nearly every consumer that they previously gained from their firm. In essence, it’s almost impossible to lower prices in an oligopolistic market and gain more power in that market. In the supermarket industry, the high usage of “brand wars”, advertising, special offers for being a loyal customer and promotions that reward shoppers are how supermarkets compete against each other; similar to that of an oligopolistic market structure.

  1. Collusion: In oligopolies, collusion can happen very easily but is frowned upon in the US and most of the EU. Collusion is when two or more firms agree to co-operate with each other to create similar benefits for each other by using each other’s resources in the market. For example, lowering the prices of their products to create a barrier within the oligopolistic market itself in order to share the consumers buying the products between each other, due to the similar prices; customers lack more choice between buying from firms. Oligopolies are the main source of collusion because of the strong impact it can have on the market. It would lead to a competition of half the market against the other 2 firms. This, of course, is highly unethical and illegal.

  1. Abnormal Profit: This is a common case in oligopolies, whereby the profit of the firms at the top of the market take in profits that are not normal (profit)– that meaning the costs are just about covered by the revenue created. Abnormal Profit refers to when the profit of a firm exceeds the average profit that firm should be making. Because of the choice between firms with prices that are practically the same in small prices; the non-price competition aspect of the oligopolistic market structure creates a situation whereby all firms enjoy abnormal profit (which is portrayed as normal profit when ...
