Paretohatárhoz

Paretohatárhoz, also known as the Pareto frontier or Pareto optimal set, is a concept used in economics and decision theory to describe a situation where resources are allocated in such a way that it is impossible to make any one individual better off without making at least one other individual worse off. This state represents an efficient allocation of resources, meaning that no further improvements can be made without some form of trade-off.

The concept is named after Vilfredo Pareto, an Italian economist and sociologist. In a Pareto efficient scenario, any attempt to improve the welfare of one person necessitates a reduction in the welfare of another. This does not necessarily imply fairness or equity; a situation can be Pareto efficient while still being highly unequal. For example, if one person has all the resources and another has none, this could be Pareto efficient if any redistribution would make the resource-rich person worse off.

Identifying the Paretohatárhoz is crucial for analyzing different economic policies and outcomes. It helps in understanding the trade-offs involved in decision-making, particularly when multiple objectives or individuals are involved. While a state of Pareto efficiency represents an ideal in terms of resource allocation, achieving it in practice is often complex due to the multitude of factors and preferences that need to be considered. The set of all Pareto efficient outcomes forms the Pareto frontier, a curve or surface that illustrates the boundaries of possible efficient allocations.
