In July 2024, a global IT outage grounded flights and disrupted hospitals and governments. The cause? A faulty CrowdStrike update impacted Microsoft software.
This showed a key flaw in our digital world: relying too much on a few big companies. Microsoft’s control of cloud computing meant that when CrowdStrike's update failed, industries everywhere suffered. Lina Khan, the US Federal Trade Commision chair, tweeted:
All too often these days, a single glitch results in a system-wide outage, affecting industries from healthcare and airlines to banks and auto-dealers. Millions of people and businesses pay the price. These incidents reveal how [market power] can create fragile systems.
This section covers market power, its growth, and its impact on economies, showing why laws are needed to limit it.

What is market power?
Market power is when one or a few businesses can control prices or market conditions. It depends on the number and size of firms. Markets with fewer and larger firms have more market power (Figure 2).
A monopoly exists when one company dominates a market. For example, Google has monopoly power in internet searches. While there are competitors like Ecosia, Bing, Safari, and DuckDuckGo, Google controls about 90% of the market, making it the clear leader.

Sometimes, natural monopolies form due to high setup costs (Figure 3). These costs make it hard for other companies to compete.
For instance, in areas with piped water, a single company usually controls the supply because building duplicate infrastructure doesn't make sense.

A monopsony occurs when there's only one dominant buyer in a market. For example, in some agricultural markets, farmers may only have one supermarket chain to sell to. This gives the supermarket power to pay lower prices to suppliers for their products and control other contract terms. The farmers have no other options. Some markets can be both monopolies and monopsonies.
An oligopoly is when a few companies dominate a market. Oligopolies can have the same power as monopolies because they can easily work together to control the market.
The global smartphone industry, with firms like Apple, Samsung, and Xiaomi, is an oligopoly (Figure 4). These companies have used anti-competitive practices, like exclusive supplier deals, to block competition.

An oligopsony happens when a few buyers control a market. For example, in the cocoa market, a few large companies buy from many small farmers. These buyers can pressure farmers to lower their prices, impacting the farmers’ incomes. With so few buyers, it's easy for them to work together to increase their power over sellers.

How do firms increase market power?
Firms can boost their market power through economies of scale, influencing laws and regulations, marketing, and anti-competitive practices.
Economies of scale
Economies of scale mean lower production costs as firms grow larger. Bigger companies can buy materials in bulk at discounted prices, borrow money at lower interest rates, and afford more efficient machines. They can also spread their advertising and design costs over a larger output, reducing the cost per unit, increasing profits.
As firms grow, they can invest profits to expand even more or lobby for favourable laws, creating a reinforcing feedback loop (Figure 6). Smaller competitors, with lower profit margins, struggle to enter the market, further strengthening the dominant firm's power.
Figure 6. Reinforcing feedback loops showing how increases in business size and market power lead to economies of scale and higher profits which lead to further increased market power (right) and political power (left).
Laws and regulations
Laws can help firms grow market power by granting them advantages like patents, which give companies exclusive rights to produce a product for a set time (Section 3.2.3). The firms with the patent can earn high profits to recover their investment costs before competitors enter the market. For example, patents for new drugs enable pharmaceutical companies to earn large profits from their innovations. While this incentivises the company to innovate, consumers, especially in poorer countries needing affordable medicines, are harmed as was the case during the Covid-19 pandemic.
Businesses also lobby for laws that benefit them or block new competitors, and they oppose laws that reduce their power, even when more competition would help the public.
Marketing tactics
Marketing includes activities businesses use to develop and sell products, covering product, price, promotion, and place. Businesses want you to buy their products repeatedly. When a firm’s sales grow faster than their competitors, a firm gains market share and power. Businesses often use sophisticated methods to boost market share and power, such as:
product positioning: Large businesses use their power to position products in ways that hurt competitors. For example, big food companies pay supermarkets to place their items at eye level, making them more likely to sell. Companies also pay Google to display their “sponsored” content at the top of search results making them more likely to be clicked.
manipulative promotion: businesses use advertising to build brand loyalty, sometimes by linking their products to personal identity or social status. Luxury brands, for instance, link their products to higher social standing. Influencers persuade people that buying certain goods will make them more attractive or popular (Figure 7).

addiction: some products are addictive, leading to repeat purchases. Classic examples include cigarettes and gambling, but social media also addicts users, keeping them on screens longer to show more ads. Addiction harms human wellbeing and, in social media, increases social tensions.
network effects: platform firms like TikTok and Amazon benefit from network effects, where a product becomes more valuable as more people use it. The more people on a platform, the more attractive it becomes, creating a reinforcing feedback loop (Section S.x). As these firms grow, leaving becomes harder due to high switching costs.
access to data: platform firms also gain power through data collection. While using free services, firms gather data on users to sell to advertisers—a practice known as surveillance capitalism. This data allows companies to influence buying behaviour and charge higher prices, leaving competitors without data at a disadvantage (Figure 8).

Anti-competitive behaviour
Some firms use anti-competitive tactics to boost market power, making it harder for others to compete. These include:
mergers and acquisitions: companies combine with competitors (merger) or buy them (acquisition) to reduce competition. For example, Facebook/Meta has bought many smaller firms to prevent them from developing competing services, stopping some innovation.
exclusive contracts and agreements: firms make exclusive deals with suppliers or distributors, blocking competitors from key resources or markets. Tech companies, for instance, may sign agreements with app developers, preventing them from offering apps on rival platforms.
bundling: companies group, or bundle, products together, making it harder for consumers to buy from competitors. For example, a software company might sell a package of programs, forcing customers to buy the whole bundle instead of a single competitor's product.
price-fixing: firms agree to set prices instead of competing. Price-fixing ensures higher profits, but is illegal in many places, as it harms consumers through high prices.
predatory pricing: large firms may temporarily lower prices to a level small competitors can’t match, driving them out of business. Once competition is gone, prices are raised again.

These strategies show how firms protect and grow market power, making it tough for new businesses to compete. Profit-maximising goals often fuel these actions, which negatively impact societies.
What are the consequences of firms’ increased market power?
When firms gain significant market power, they often harm society and Earth systems. Like ecosystems, economies need diversity to be resilient. Concentrated market power weakens economies by raising prices, reducing innovation, lowering product quality, and increasing economic inequality, political capture, and environmental damage. There is an activity at the end of this section that will help you think about each of these impacts more carefully.
Capitalism and market power are closely linked. Capitalism seeks to maximise profits, and market power helps firms raise prices, cut costs, and influence laws in favour of business. To profit, firms aim to dominate markets.
Market concentration has grown globally, with a few firms controlling essential markets like food and energy, reducing choice and raising prices. Despite claims that capitalism promotes competition, profit-driven firms often seek monopoly power, as famous tech investor Peter Thiel highlights in the first 50 seconds of the video below titled "Competition is for losers."
Activity 3.2.4
Concept: Power
Skills: Thinking skills (transfer and critical thinking)
Time: varies depending on option
Type: Individual, pairs, or group
Option 1: Linking market power to economic, social and ecological problems
Time: 30 minutes
This section outlined some negative impacts of market power for society and Earth systems: political capture, environmental harm, less economic resilience, higher prices, reduced innovation, lower quality products, and economic inequality.
Alone or with a partner, think through the links between market power and each of these impacts. What’s the connection?
Write or verbally discuss your ideas. You can check your ideas against information by clicking on the arrow.
political capture: firms with significant market power can successfully lobby for favourable laws and regulations, often at the expense of public interest. This undermines democracy and leads to policies that prioritise business profits over social well-being. We see this with large fossil fuel companies that have influenced governments’ energy policies, hindering the development of renewable energy.
environmental harm: large profit-maximising firms often harm the environment, through deforestation, pollution, and overfishing. For example, a few large companies dominate the market for seeds and pesticides. They promote monoculture farming which undermines soil health and reduces biodiversity.
less economic resilience: If one or a few firms dominate a market it makes our economies more vulnerable to disruptions, as you read about the CrowdStrike outage that affected Microsoft’s cloud computing systems.
higher prices: when firms control the market, they can set high prices, making goods and services more expensive for people to buy, harming their ability to meet other needs.
reduced innovation: when a few firms dominate, they may lack the incentive to innovate, leading to stagnation.
lower quality products: with little or no competition, dominant firms might reduce their focus on quality, knowing consumers have limited alternatives.
economic inequality: Firms with significant market power can influence wages and working conditions, often to the detriment of employees. For instance, Walmart has been criticised for paying low wages and offering poor working conditions, despite the company's vast profits. This can create a cycle of poverty and insecurity for workers, limiting their economic mobility and overall wellbeing.
Option 2: Considering market power in your community
Time: 30-40 minutes
People face oligopolies or monopolies now for many of their daily needs, such as food, water, mobility, communication and energy.
Make a list of some goods and services that your household buys regularly.
Think about the businesses in your local community that provide these goods and services. For each good or service, list as many businesses as you can that sell it.
It may be easier to do this as a small group or whole class to combine everyone’s local knowledge. If you have access to one, you can also use the search function in a mapping app to see what comes up.
Consider the list you made, identifying the businesses that may have monopoly or oligopoly power in your community. Which of these, if any, are branches of large businesses that may exist on a national or international scale? Which of these are locally owned?
What implications might there be of the patterns of market power that you have found in your local community?
Option 3: Considering market power in social media
Time: 20 minutes
One concern with companies achieving too much market power is that they will harm consumers, often through raising prices. With the major social media businesses, for example Meta (owner of Instagram) and TikTok, this doesn’t appear to be the case. Many of the services these companies offer do not cost consumers money. Some questions to consider or discuss with a partner, small group or as a class:
Are these social media services really for free? Why or why not?
How much choice do you have about whether to participate in social media networks? Consider the impact of network effects in your own life.
Competition authorities in some countries are challenging Meta in court, claiming that the company is an illegal monopoly with the aim of getting it to change its practices. Given what you have read in this section, and considering any of your own experiences, do you think that states should more strictly limit the power of social media or other tech firms? Why or why not?
