Oligopoly is the most complex market structure, characterised by a few large firms which dominate the industry. Typically there are high barriers to entry and prices can be very sticky. However, perhaps the most important characteristic is interdependence. With this feature of the market, oligopolies, despite being dominated by a few big firms, can be the most competitive market structure.
There are many examples of oligopolies and one of the best is the supermarket industry. Dominated by the likes of Tesco, Morrisons and Asda, competition in terms of branding, product development and quality is constant, but so is price competition. During the recession, you could hardly watch a TV programme that included advert breaks without seeing one of the big four advertising their low prices.
However, in the past few years, the supermarket industry has seen competition grow even further and the big four are now facing competition from low-cost retailers, including Aldi and Lidl. This has led to falling sales and profits for the likes of Tesco and Morrisons.
Tesco, Morrisons, Sainsbury’s and Asda have all felt the emergence of discount retailers and have seen their customer numbers fall. All have reacted with rounds of price cuts and new deals, and this price war looks set to continue. Morrisons have just announced a 14% average price cut on 135 products to match earlier changes in pricing strategies by the other main competitors. As I’m writing this during the Algeria v. South Korea match, I have just seen an advert from Sainsbury’s, promoting their milk chocolate digestive biscuits, priced at £1. The advert explicitly states that they are ‘less than Morrisons’, where the price is £1.50. This was soon followed by another from Sainsbury’s saying that the Cif bathroom spray is £1.50, which is ‘less than Tesco’, priced at £2.75. I need say no more.
So, what is it about this industry which means it is so susceptible to price wars? Are all oligopolies like this? The following articles consider the supermarket industry and the price wars that have emerged. Think about this sector in terms of oligopoly power and consider the questions that follow.
