Understanding Externalities: What You Need to Know
Externalities are costs or benefits that affect people who are not directly involved in a transaction. These can really change how well our economy works and how happy people are overall. There are two main types of externalities: positive and negative.
What They Are: Negative externalities happen when someone's actions harm others. A good example is pollution from factories, which affects the air we breathe.
How It Affects Us: Negative externalities can cause too much production. For instance, a study found that air pollution costs Europe about €250 billion each year. This is because it causes health problems and makes people less able to work.
The Real Cost: The true cost to society includes both the cost of production and the extra costs from these negative effects. This can lead to a situation where more is produced than is good for the public.
What They Are: Positive externalities give benefits to people who aren’t directly part of an activity. For example, getting a good education not only helps the individual but also makes society better.
How It Affects Us: Positive externalities can lead to too little production. The benefits for society can be greater than just the benefits for the person involved. For example, one study showed that every extra year of school can boost a person’s earnings by about 10%.
The Real Benefit: The social benefit includes both personal gains and the good things that others get from it. This can lead to less being produced than what would be best for society as a whole.
Fixing the issues caused by externalities can help our economy work better and improve people’s lives. Using taxes or subsidies can help ensure that resources are used wisely and everyone benefits.
