Fractional Pareto efficiency is a strengthening of Pareto efficiency in the context of fair item allocation. An allocation of indivisible items is fractionally Pareto-efficient (fPE or fPO) if it is not Pareto-dominated even by an allocation in which some items are split between agents. This is in contrast to standard Pareto efficiency, which ...
Kaldor–Hicks efficiency. A Kaldor–Hicks improvement, named for Nicholas Kaldor and John Hicks, is an economic re-allocation of resources among people that captures some of the intuitive appeal of a Pareto improvement, but has less stringent criteria and is hence applicable to more circumstances. A re-allocation is a Kaldor–Hicks ...
Economic efficiency. In microeconomics, economic efficiency, depending on the context, is usually one of the following two related concepts: [1] Allocative or Pareto efficiency: any changes made to assist one person would harm another. Productive efficiency: no additional output of one good can be obtained without decreasing the output of ...
If there exists a network which is not Pareto dominated by another network then it is a Pareto efficient network. In the figure "An Example of Efficient, Pareto Efficient, and Pairwise Stable Networks in a Four Person Society" an example with four players is given, where the payoffs of the players are noted by the numbers next to the nodes.
Pareto front. In multi-objective optimization, the Pareto front (also called Pareto frontier or Pareto curve) is the set of all Pareto efficient solutions. [1] The concept is widely used in engineering. [2]: 111–148 It allows the designer to restrict attention to the set of efficient choices, and to make tradeoffs within this set, rather than ...
A Pigouvian tax is a method that tries to internalize negative externalities to achieve the Nash equilibrium and optimal Pareto efficiency. [1] The tax is normally set by the government to correct an undesirable or inefficient market outcome (a market failure) and does so by being set equal to the external marginal cost of the negative ...
Multi-objective optimization or Pareto optimization (also known as multi-objective programming, vector optimization, multicriteria optimization, or multiattribute optimization) is an area of multiple-criteria decision making that is concerned with mathematical optimization problems involving more than one objective function to be optimized simultaneously.
The Lange model contains principles proposed by neoclassical economists Vilfredo Pareto and Léon Walras. Lange's theory emphasizes the idea of Pareto efficiency: a situation is Pareto-efficient if there is no way to rearrange things to make any individual better off without making anyone worse off.
