Pareto distributions are commonly used in economics and finance.

Pareto optimality is a concept in economics that represents an efficient allocation of resources.

Pareto efficiency is achieved when no individual can be made better off without making someone else worse off.

Pareto's law states that 80% of the effects come from 20% of the causes.

The Paretoan principle states that a distribution of resources is optimal if it is impossible to make any individual better off without making someone else worse off.
