Welfare economics is a field of economics that applies microeconomic techniques to evaluate the overall well-being of a society, often informing public economics and serving as the foundation for cost-benefit analysis. The principles of welfare economics have been applied in various contexts, including environmental economics, as seen in the work of the Intergovernmental Panel on Climate Change (IPCC) and the research of economists like Joseph Stiglitz and Amartya Sen. The concept of welfare economics has been influenced by the work of Adam Smith, who introduced the idea of the invisible hand, and has been further developed by economists such as John Maynard Keynes and Milton Friedman.

The theoretical foundations of welfare economics are based on two fundamental theorems. The first states that competitive markets, under certain assumptions, lead to Pareto efficient outcomes, as described by economists like Vilfredo Pareto and Leon Walras. 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 system of taxes and subsidies, as discussed by economists like James Mirrlees and William Vickrey. These theorems have been influential in shaping the field of public economics, with applications in policy areas such as taxation, regulation, and social welfare programs, as seen in the work of the World Bank and the International Monetary Fund (IMF).

The applications and policy implications of welfare economics are diverse and far-reaching. Welfare economics has been used to evaluate the effectiveness of government interventions, such as the Affordable Care Act (ACA) in the United States, and to inform policy decisions on issues like climate change, as seen in the work of the European Union's climate policy and the research of economists like Nicholas Stern. The principles of welfare economics have also been applied in the context of development economics, with economists like Jeffrey Sachs and Paul Collier working to improve the well-being of people in developing countries. Additionally, welfare economics has been used to analyze the impact of technological change on societal well-being, as seen in the work of economists like Erik Brynjolfsson and Andrew McAfee.

The intersection of welfare economics and behavioral economics has given rise to the subfield of behavioral welfare economics, which has been explored by economists such as Richard Thaler and Cass Sunstein. This subfield recognizes that individuals do not always make rational decisions, and that behavioral biases and heuristics can affect economic outcomes. Behavioral welfare economics has been used to inform policy decisions on issues like consumer protection, financial regulation, and public health, as seen in the work of the Consumer Financial Protection Bureau (CFPB) and the research of economists like Sendhil Mullainathan and Eldar Shafir.
