Externaliteiten

Externalities are outcomes of economic activities that affect third parties who are not directly involved in it. These impacts can be either positive or negative.

Positive externalities occur when an economic activity generates benefits for third parties.

An example is beekeeping. When a beekeeper maintains a hive, the bees pollinate surrounding crops. This benefits farmers in the vicinity who receive improved crop production without any cost or effort on their part.

However, the beekeeper is not financially compensated for producing these benefits, even though their beekeeping activities create a significant positive impact on agricultural productivity.

Negative externalities, on the other hand, happen when an economic activity imposes costs on unrelated third parties.

A common example is pollution. A factory might emit pollutants into the air as a byproduct of its production process, harming the health of people living nearby who have no direct relationship with the factory.

The factory does not bear the full cost of the higher pollution levels and the health impacts created by it.
