Theory of the firm

The theory of the firm consists of a number of economic theories that explain and predict the nature of a firm: for example, a business, company, corporation, and more. These theories look at why firms exist, how they stay running, how they behave, and how they are organized. Firms are very important in economics because they provide goods and services that people want and need, and in return, they receive money.

The way a firm is organized, how it gives rewards, how productive its workers are, and how it uses information all affect whether the firm does well. Because of this, big economic ideas like transaction cost theory, managerial economics, and the behavioural theory of the firm help us understand different kinds of firms and how they are managed. These ideas give us conceptual frameworks to study firms more deeply and see what makes them successful.

Overview

The Theory of The Firm tries to explain why businesses exist and how they work. It asks questions like why some work is done inside companies instead of through buying and selling in the market. Firms help make things more efficient. For example, it can be hard and expensive for companies to hire and fire workers every day based on how much they need to make. By having long-term agreements with workers and suppliers, companies can save money and create more value.

Background

During the First World War, economic ideas began to shift from studying whole markets to looking more closely at individual businesses. Before this, most economic thinking only looked at markets, not why businesses or organizations exist. Markets are places where prices and quality decide what happens, like when you buy vegetables and can choose between different sellers. Studies by Adolf Berle and Gardiner Means showed that in many American corporations, control was held by managers who did not own much of the company, while many shareholders owned small pieces. Researchers like R. L. Hall and Charles J. Hitch discovered that business leaders often made choices based on simple rules rather than complex calculations.

Transaction cost theory

Main article: Transaction cost

According to Ronald Coase, people start forming businesses when it costs less to work together inside a company than to buy and sell things in the market. Coase explained this idea in 1937, trying to understand why companies exist compared to just using the market.

Coase suggested that companies help avoid some of the costs of using the market. For example, it can be hard to find the right prices or make many contracts every time you buy or sell something. Inside a company, there are fewer contracts because a manager can tell employees what to do. This works better when things are uncertain and when transactions need to happen over long periods of time. He believed that companies grow when it’s cheaper to handle transactions inside the company rather than through the market. The size of a company depends on balancing these costs.

Managerial and behavioural theories

In the 1960s, new ideas about how businesses work started to appear. These ideas suggested that managers in companies might not always aim to make the most profit. Instead, they could focus on their own interests, like getting higher pay or more power, as long as the company still makes enough profit.

One important idea is called "bounded rationality." This means that people can’t always make the perfect decision because they have limited knowledge and time. Because of this, companies often aim for realistic goals instead of trying to be the absolute best. Different people inside a company might have different goals, and the company's actions are a balance of these different ideas.

Asset specificity

For Oliver E. Williamson, businesses exist because of "asset specificity" in making things. This means that some tools or skills are very special and work best together, but not as well with other things. If these special tools are owned by different companies, like a buyer and a seller, they might argue a lot about who gets the benefits. This can make it hard for both sides to act fairly.

If the same company needs to keep working together for a long time, they may need to keep changing their agreement because of power struggles. Sometimes, one company might ask another to make a special investment that would help both, but after it's done, the first company might try to change the deal so the second company loses money. To avoid these problems, companies sometimes join together through takeover or merger. This idea of asset specificity can also happen with people’s skills, where workers might threaten to stop working unless they get more, or the company might decide to let workers go.

A good way to prevent unfair behavior is through reputation. If a company gets a bad reputation for being unfair, it will hurt their future business. This helps change the incentives to act unfairly. Williamson also thought that big companies might struggle because of the costs of delegation and the growth of their bureaucracy. As companies grow, they can’t always give the same strong rewards to employees as smaller companies can, which can lead to less effort from workers.

Boundaries of the firm

The boundaries of a firm look at why and how firms decide their size and the kinds of products they make. Firms can choose to be broad, offering many different products, or deep, controlling more steps in making and selling their products. Being broad helps a firm use skills like marketing and customer service to offer many products together, which can save money. Being deep means the firm can make and sell products more efficiently by controlling more parts of the process, but this can also mean more management work.

This idea connects to how firms decide whether to make things themselves or buy them from others, depending on what works best for them.

Economic theory of outsourcing

In economic theory, people have talked about the good and bad sides of outsourcing since Ronald Coase asked why everything isn't made by one big company. Oliver Williamson explained that the costs of doing business deals, both inside and between companies, play a big role. Oliver Hart and others studied how these business deals work and found that who owns what matters when deciding whether to do something inside the company or outside. This depends on how important the investments are for each part. If one side has to make a big investment that can't be fully planned ahead, that side should own the activity. These ideas depend on how deals are talked about and if there is missing information.

Firm as a sociotechnical system

The idea of seeing businesses as sociotechnical systems started with studies by researchers at The Tavistock Institute of Human Relations. Scholars like Trist and Bamforth, and Emery and Trist, noticed that businesses can be understood as systems that mix people and technology. These systems can change and adapt to meet their goals.

This approach looks at businesses not just as money-making places, but as places where people and tools work together. It shows how the way people interact and the tools they use are linked. The success of a business depends on both its tools and the relationships among its people.

Evolutionary and Complexity Theory-Based Approaches.

Evolutionary ideas about firms started with the work of Joseph A. Schumpeter. He thought each firm has its own special way of working. He brought together how firms are made and managed into one theory. Schumpeter saw firms as always changing, learning, and creating new ideas.

Terra and Passador added to this idea. They said firms are more than just making money. They are places where people and tools work together in a special way. In these firms, people and tools help each other, like two parts of a whole. The firm keeps itself going by getting and sending information and resources. It changes over time to stay strong and keep its identity.

For a firm to stay strong, it needs to bring in new people, keep getting resources, offer good reasons for people to join, and be able to fix itself if someone leaves. Firms also need to watch out for changes in the world around them, like changes in markets or society, so they can keep going strong.

Other models

Some ideas about why businesses work the way they do look at how pay and rewards affect workers. For example, one idea says that paying workers more than the minimum can make them work harder because they don’t want to lose that higher pay. Another idea suggests that giving workers chances to move up in the company can also motivate them to work harder.

Another thinker argued that the size of a business isn’t just about being efficient — it’s also about relationships and trust between workers and managers. When people care about each other, they often work harder, even without being closely watched.

Recently, someone questioned the old idea that businesses and markets are completely different. They pointed out that many important projects today, like making computer programs that anyone can use or editing online encyclopedias, are done by groups of people working together without traditional business structures.

Grossman–Hart–Moore theory

In modern contract theory, the "theory of the firm" is often linked to the "property rights approach" developed by Sanford J. Grossman, Oliver D. Hart, and John H. Moore. This approach is also called the "Grossman–Hart–Moore theory."

These thinkers argued that because contracts can’t cover every possible situation, who owns the property matters. For example, when a seller and a buyer make important decisions, who should own the tools or assets needed? The theory shows that the person who makes the biggest investment should usually be the owner. This helps encourage better decisions and investments.
