What is Pareto optimal outcome?
Consequently, what does it mean to be Pareto optimal?
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.
Similarly, why is Pareto efficiency important? Pareto efficiency is important because it provides a weak but widely accepted standard for comparing economic outcomes. A policy or action that makes at least one person better off without hurting anyone is called a Pareto improvement. The term is named for an Italian economist, Vilfreo Pareto.
Thereof, what it means for an outcome to be Pareto dominated by another?
Pareto Dominated. An outcome of a game is Pareto dominated if some other outcome would make at least one player better off without hurting any other player. That is, some other outcome is weakly preferred by all players and strictly preferred by at least one player.
What is Pareto efficiency examples?
Example. Consider an economy that contains only one good, which everyone likes. Then every allocation is Pareto efficient: the only way to make someone better off is to give them more of the good, in which case someone else will have less of the good, and hence be worse off.
