Pareto optimality

a theoretical condition of the economy in which the distribution of economic welfare cannot be improved for any one individual without reducing the welfare of one or more other individuals. Thus a ‘Pareto improvement’ occurs when a reallocation of resources renders one or more persons better off. In any situation where more than one optimum is possible, Pareto optimality cannot be established.

In that case, Pareto optimality is not socially optimal at all.
The first theorem of welfare economics is Pareto optimality, which states that an economy is in an equilibrium constituting optimum welfare when all exchanges of goods between economic actors have taken place, this being identified by the impossibility of a reallocation of goods that would not leave at least one actor worse off.
In economic terminology, the term "efficiency" refers to the idea of Pareto optimality, or, alternatively, to other concepts (such as Kaldhor-Hicks efficiency and social welfare maximization) commonly used in policy analyses to overcome the restricted practicability of the Pareto efficiency criterion.
In the above setup, we analyze investment and premium policies ([alpha], p) [member of] V based on the weak criterion of Pareto optimality.
As the obtained design values are evaluated against multiple criteria, Pareto optimality concept is applied in the analysis phase.

32) Because "there is no readily apparent correlation between Pareto optimality and more central attributes of justice, like distributional equality," Sager concluded that reliance on the Pareto principle for resolving all issues of justice is deeply problematic.
17) The idea that the Coase theorem was basically a restatement of Pareto optimality and a tautology had been expressed seven years earlier by Calabresi (1968: 68), though we cannot ascertain whether Swan was familiar with Calabresi's discussion.
There is no need to single out certain targets in this overall process, under the definitions of Pareto improvement and Pareto optimality discussed above.

As with most two-player games of this structure, Pareto optimality may only be obtained through coordination.
The significance and useful potential attributed to the proposed Pareto optimality efficiency network model lies in: (a) considering the impact of external financial constraints and project parameters on cash flow transaction forecast; (b) providing decision alternatives through scenario analysis by changing these external constraints and parameters; (c) trading-off profitability/final cash balance and loan interests, which are two of the most important issues in project cash flow planning and management; (d) the effective cash flow forecasting technique with reasonable accuracy and without time-consuming data collection.
