Oligopoly is a type of market where just a few companies hold most of the control. This can really change how businesses behave and affect what we pay for products or services. Let’s break down what this means for market power and competition.
In an oligopoly, a small number of companies control a big part of the market—usually between 40% and 70%.
Take the cell phone service or car industries, for example. Companies like Vodafone and BMW have a lot of power to set prices. Because there are few players, they can charge more than in a market with lots of competition.
We can check how much market power these companies have using something called the Lerner index. It’s a formula that tells us how much higher the price is compared to the cost to make the product. When the Lerner index is more than 0.3, it shows that these companies have big markups on their prices.
A key trait of oligopoly is that companies are slow to change prices. They worry that if they raise prices, customers might leave for competitors. A survey showed that over 70% of these companies prefer to keep prices steady, even if their costs go up.
This leads to something called kinked demand curves, which means customers are more likely to buy less if prices go up, but they won’t buy more if prices go down. So, instead of competing with price, companies focus on things like advertising and making their products stand out.
Companies in an oligopoly might work together to increase their profits, a practice known as collusion. Sometimes they form a cartel, which is an agreement to set prices or control how much they produce. A well-known example is OPEC in the oil industry, where member countries work together to influence oil prices. This can make oil prices higher for everyone and affect economies all over the world.
Because companies are careful about changing prices, they often compete in other ways. This could mean spending a lot on ads, improving products, or offering better customer service.
For instance, Apple and Samsung invest billions in ads and product development. In 2020, Apple alone spent about $21 billion on marketing, showing that they focus on building strong brands rather than just lowering prices.
Oligopolies often stay strong because it is tough for new companies to enter the market. There are many obstacles, like needing a lot of money to start up, having strong brand names, and facing strict laws. The World Bank notes that in areas like airlines and banking, these barriers are particularly high. This keeps new competition from coming in and can slow down innovation.
Oligopolies impact everyday people, as less competition usually means fewer choices and higher prices. The Organisation for Economic Co-operation and Development (OECD) states that in these markets, consumers can pay up to 20% more than they would in a perfectly competitive market. While we might see some new and cool products, the overall cost for consumers can go up because of this lack of competition.
In summary, oligopolies play a big role in shaping how companies compete and how much power they have in the market. By knowing how these systems work, we can better understand their effects on pricing, consumer choices, and the overall economy. It’s important for regulators to keep an eye on these companies to ensure they don’t take advantage of consumers.
