2. ### Pareto efficiency - Wikipedia

en.wikipedia.org/wiki/Pareto_efficiency

Pareto efficiency or Pareto optimality is a situation that cannot be modified so as to make any one individual or preference criterion better off without making at least one individual or preference criterion worse off. The concept is named after Vilfredo Pareto (1848–1923), Italian engineer and economist, who used the concept in his studies of economic efficiency and income distribution. The following three concepts are closely related: Given an initial situation, a Pareto improvement is ...

3. ### Pareto principle - Wikipedia

en.wikipedia.org/wiki/Pareto_principle

The Pareto principle is only tangentially related to Pareto efficiency. Pareto developed both concepts in the context of the distribution of income and wealth among the population. Mathematically, the 80/20 rule is roughly followed by a power law distribution (also known as a Pareto distribution) for a particular set of parameters, and many natural phenomena have been shown empirically to exhibit such a distribution.

The result of this is called Pareto efficiency, named after Vilfredo Pareto, who first used it in his studies. In economics, the idea of Pareto efficiency is very simple: If there is no way of improving the situation of one person, without making that of another person worse, the solution found is Pareto-efficient.

Efficiency and fairness are two major goals of welfare economics. Given a set of resources and a set of agents, the goal is to divide the resources among the agents in a way that is both Pareto efficient (PE) and envy-free (EF). The goal was first defined by David Schmeidler and Menahem Yaari.

7. ### Kaldor–Hicks efficiency - Wikipedia

en.wikipedia.org/wiki/Kaldor–Hicks_efficiency

Under Kaldor–Hicks efficiency, an improvement can in fact leave some people worse off. Pareto-improvements require making every party involved better off (or at least none worse off). While every Pareto improvement is a Kaldor–Hicks improvement, most Kaldor–Hicks improvements are not Pareto improvements.

Pareto Efficiency Confused about definition: "Pareto efficiency or Pareto optimality is a state of allocation of resources from which it is impossible to *reallocate* so as to make any one individual or preference criterion better off without making at least one individual or preference criterion worse off"

9. ### Bayesian efficiency - Wikipedia

en.wikipedia.org/wiki/Bayesian_efficiency

Bayesian efficiency is an analog of Pareto efficiency for situations in which there is incomplete information. Under Pareto efficiency, an allocation of a resource is Pareto efficient if there is no other allocation of that resource that makes no one worse off while making some agents strictly better off.

10. ### Pareto distribution - Wikipedia

en.wikipedia.org/wiki/Pareto_distribution

The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, is a power-law probability distribution that is used in description of social, scientific, geophysical, actuarial, and many other types of observable phenomena.
