Competition (economics)

Many shops try to sell things.

They want you to pick them.

Some shops try to have lower prices. Others try to make better things. This helps us get more choices.

Sometimes, only one shop sells a thing. This is called a monopoly. It can be hard for new shops to join in.

Other times, only a few big shops sell things. This is called an oligopoly. They may work together to set prices.

Competition helps make the world work. It can lead to new tools and better goods.

In a market, different companies try to sell goods. This is called competition.

Companies use many ways to win. They may lower their prices. They may make better products. They may use new ads to find buyers.

This can be good for people. Competition gives us more choices. It often makes prices go down. It also helps companies make new tools.

Some markets are not perfectly fair. In a monopoly, only one company sells a thing. It is hard for new firms to join. This can lead to high prices.

In an oligopoly, only a few big firms sell things. Sometimes these firms work together. They might set prices to make more money. Governments often watch these markets. They want to make sure things stay fair.

There is also monopolistic competition. In this way, many firms sell similar things. But the products are not exactly the same. This lets each firm set its own price.

Competition is a very important part of how markets work. It happens when different companies, or firms, try to get the same customers. These firms compete to sell their goods and services to people. They can do this by changing their prices or their products. They might also use special ads or pick better places to sell.

When many companies compete, it often helps the people buying things. It can lead to more choices and lower prices for everyone.

There are different ways to look at how competition works. Some people study how many sellers are in a market. They also look at how big or small those sellers are. If the largest company is small, competition is usually very strong.

Other factors like how much information buyers have also matter. If buyers know a lot about prices, they can make better choices. This helps keep the market moving and keeps things fair.

Economists have studied this idea for a long time. In the 1800s, a man named Antoine Augustin Cournot studied it. He looked at how prices change when the amount of goods changes. He used math to explain how competition works in a system.

Today, researchers still look at how companies work together in groups. They study how companies in the same area can help each other. This can create strong networks of suppliers and buyers.

Scientists often talk about two main types of markets. The first type is called perfect competition. In this model, many small firms sell the exact same thing. No single firm is big enough to control the price.

The second type is called imperfect competition, which is more common in real life. In these markets, companies can influence prices and sell different products. This is what we see most often in our everyday world.

Imperfect competition includes several different structures. A monopoly happens when only one firm sells a product. This makes it very hard for new companies to join the market. An oligopoly is when just a few large firms control things.

For example, a few big airlines might dominate a certain flight path. There is also monopolistic competition where many firms sell similar items. These items are not exactly the same, so companies can set their own prices.

In economics, competition is a scenario where different firms contend to obtain goods. These firms can be individuals, brands, or even divisions within a single legal company. They compete by varying elements of the marketing mix. These elements include price, product, promotion, and place.

When firms compete, they often develop new products and technologies. This process gives consumers more selection and better quality. Higher selection in a market typically leads to lower prices for products. This is a major difference compared to markets with little competition.

Competitiveness refers to the ability of a firm or country to supply goods. It is measured by how well a firm performs against its rivals. The word comes from the Latin "competere," meaning rivalry between entities. To measure competition, economists look at the number of rivals in a market. They also look at how similar the firms are in size. If the largest firm has a small share of the output, competition is vigorous.

Many factors influence this level, such as barriers to entry and resource availability.

Economic thought regarding competition has changed over time. Early research focused on price versus non-price competition. Modern theory focuses on the many-seller limit of general equilibrium. In the 19th century, Antoine Augustin Cournot provided a mathematical definition. He described competition as a situation where price does not vary with quantity. In this model, the demand curve facing the firm is horizontal.

This helps explain how firms behave in different market structures.

Neoclassical theory describes a theoretical state called perfect competition. This state is rarely observed in the real world. In perfect competition, all firms contribute insignificantly to the market. Every firm sells an identical product, often called a perfect substitute. Firms are "price takers," meaning they cannot influence the market price. Buyers and sellers both have complete or "perfect" information. Resources are perfectly mobile, and firms can enter or exit without cost.

In the long run, these firms earn zero economic profit.

Most real-world markets involve imperfect competition. In these markets, buyers and sellers can influence prices and production. Companies sell different products and fight for market share. They are often protected by barriers to entry. These barriers make it difficult for new firms to challenge them. Imperfect competition includes monopolies, oligopolies, and monopolistic competition. These structures allow firms to generate more profit than in perfect competition.

A monopoly is the opposite of perfect competition. In a monopoly, one single firm holds the entire market share. This firm dictates the entire market instead of being defined by it. Monopolies use high barriers to entry to discourage new competitors. A "natural monopoly" occurs due to high start-up costs or economies of scale. These can arise in industries requiring unique technology or raw materials. Some monopolies form through mergers or acquisitions. Others might use collusion, where rivals conspire to fix prices.

An oligopoly occurs when a small number of firms dominate a market. This is a highly concentrated market structure. A special type of oligopoly is a duopoly, which consists of only two firms. In an oligopoly, firms may collude to restrict output or fix prices. This helps them achieve above-normal market returns. Major airline companies often act as oligopolies.

Governments often regulate these markets to prevent overcharging consumers.

Finally, monopolistic competition involves many firms offering similar products. These products are not perfect substitutes, meaning they have slight differences. Barriers to entry and exit in these industries are low. The decisions of one firm do not directly affect its competitors. This structure allows for a mix of competition and individual brand control. Understanding these different models helps explain how global economies function and evolve.
