How goods are defined in economics?

In economics, goods mean the items which can satisfy human needs and wants by providing a utility. In other words, to buy a good or service by a customer, there should be a satisfaction. There are 4 types of goods in economics. They are private goods, club goods, common resources, and public goods.

The main difference between goods and services are that goods are transferable (can be transferred from one party to another party) while services are not transferable.

Also, according to economists, a producer takes resources from the environment and produces outputs (goods and services).

What are the four types of goods in economics?

There are 4 types of economic goods. They are

1. Private goods

2. Club goods

3. Common goods or common resources

4. Public goods.

These four types of goods in economics are categorized based on two major characteristics. They are excludability and rivalry in consumption.

Excludability

Excludability means, the ability to remove the people who haven’t paid for the particular good from using it. In other words, if a person has not paid the price of the good or service, he or she cannot consume it. For consumption, a price must be paid. 

Rivalry

The second characteristic is rivalry in consumption. It means there is competition for the consumption of a particular good. In other words, if one person consumes a particular good, another person cannot consume it. There is a marginal cost of using the goods. For one person’s consumption other person has to sacrifice the consumption.

Let’s, consider about four types of economic goods based on their major characteristics.

1.Four types of goods in economics: Private goods

Private goods both excludable and rival in consumption. If a person has not paid the price of the private good or service, he or she cannot consume the private good (excludable). If one person consumes a private good, another person cannot consume that good (rival).

2. Four types of goods in economics: Club goods

Club goods are goods with excludability and non-rivalry in consumption. If a person has not paid the price of the club good or service, he or she cannot consume the club good (excludable). Consumption of a club good by a particular person does not limit the consumption of that good by another person (non-rivalrous).

As an example, when we consider about cinema, we have to buy a ticket to watch a film. That means there is a price for it and if we cannot pay it, we cannot consume the particular good. We cannot watch the film without buying a ticket. So, excludability is there. But we can watch a film as a group. Consumption of the good by a particular person does not limit the consumption of that good by another person up to a certain level. So, we can say there is no rivalry in consumption.

3. Four types of goods in economics: Common resources

The third category is the common resources. Common resources are not excludable and rival in consumption. Although a person has not paid for the common resource, he or she can consume the common resources (non-excludable). If one person consumes common resources, another person cannot consume them (rival).

 If we take forests as an example of common resources, we know that anyone can use the forests without paying a price. So, they are not excludable. But if one person cut a tree in the forest and make a table on behalf of him, another person cannot use that tree for his purpose. Because common resources are rivalry in consumption.

Most of the time, people use common resources than their optimum level. So, there is a problem with excessive usage of common resources and in the future, there will be a shortage in common resources. So, the government should take necessary actions to maintain optimum usage of common resources.

4. Four types of goods in economics: Public goods

The last good category is public goods. Public goods are not excludable and not rival in consumption. Although a person has not paid for public goods, he or she can consume the public goods (non-excludable). Consumption of a public good by a particular person does not limit the consumption of that good by another person (non-rivalrous).

When we consider lighting houses as an example of public goods, we haven’t to pay any fee to use lighting houses. It is free of charge and there is no excludability. Also, any number of people can use the service of a lighting house, and consumption of the service of a lighting house by a one-person does not limit the consumption of the service by another person. So, there is no rivalry in consumption.
