[This is part of the series: The Complete Guide To Economics 101.]
As referred to in economics, what is rivalry?
Rivalry is the use of a good that diminishes the use by another person.
For example:
- If you eat an apple, I can not eat it.
- But, if you read a post I have written, you can share it everywhere, and everyone else can read it too.
- If you buy a wedding dress, another girl is prevented from having that dress.
- But, your love for your first child is in no way diminished by having a second child.
