<p><b>New page</b></p><div>'''Welfare economics''' is the branch of [[economics]] that evaluates the well-being of society as a whole and assesses the desirability of alternative economic arrangements. It provides a framework for judging whether a particular allocation of resources is efficient and how it affects social welfare.<ref name="wiki">Wikipedia contributors, "Welfare economics".</ref><br />
<br />
== Core concepts ==<br />
<br />
Welfare economics is built around several central ideas:<br />
<br />
* '''Social welfare''' — a measure of the overall well-being of a society.<br />
* '''[[Efficiency]]''' — the allocation of resources such that no one can be made better off without making someone else worse off (Pareto efficiency).<br />
* '''Equity''' — the fairness of the distribution of resources and income.<br />
* '''Social welfare functions''' — mathematical representations of how individual utilities combine into social welfare.<br />
<br />
== Fundamental theorems ==<br />
<br />
Welfare economics rests on two fundamental theorems:<br />
<br />
{| class="wikitable"<br />
! Theorem<br />
! Statement<br />
|-<br />
| First theorem<br />
| Under certain conditions, a competitive equilibrium is Pareto efficient.<br />
|-<br />
| Second theorem<br />
| Under certain conditions, any Pareto-efficient allocation can be achieved by a competitive equilibrium with appropriate transfers.<br />
|}<br />
<br />
These theorems establish a link between competitive markets and efficiency but say nothing directly about equity, which must be addressed through redistribution.<ref name="wiki"/><br />
<br />
== Applications ==<br />
<br />
Welfare economics provides the theoretical foundation for [[cost–benefit analysis]], the evaluation of policy interventions, and the analysis of [[Market Failure|market failure]]. It is closely related to [[Public Economics]] and underpins much of the analysis of taxation and regulation.<ref name="wiki"/><br />
