- "Welfare economics is a field of economics that applies microeconomic techniques to evaluate the overall well-being (welfare) of a society."
The study of how to measure the overall welfare of society, including the concepts of efficiency, equity, and social welfare functions. Used to evaluate the effects of policy interventions on the well-being of different groups.
- "This evaluation is typically done at the economy-wide level, and attempts to assess the distribution of resources and opportunities among members of society."
- "The principles of welfare economics are often used to inform public economics, which focuses on the ways in which government intervention can improve social welfare."
- "Additionally, welfare economics serves as the theoretical foundation for several instruments of public economics, such as cost–benefit analysis."
- "The intersection of welfare economics and behavioral economics has given rise to the subfield of behavioral welfare economics."
- "The first states that competitive markets, under certain assumptions, lead to Pareto efficient outcomes. This idea is sometimes referred to as Adam Smith's invisible hand."
- "The second theorem states that with further restrictions, any Pareto efficient outcome can be achieved through a competitive market equilibrium, provided that a social planner uses a social welfare function to choose the most equitable efficient outcome and then uses lump sum transfers followed by competitive trade to achieve it."
- "Arrow's impossibility theorem, which is closely related to social choice theory, is sometimes considered a third fundamental theorem of welfare economics."
- "Welfare economics typically involves the derivation or assumption of a social welfare function."
- "Such functions often include measures of economic efficiency and equity, as well as other measures such as economic freedom as described in the capability approach."
