This is a collective analysis of five major economic theories of welfare. Here each of the theories is explained separately in a brief manner. The diagrammatic representation is also used here to understand the concepts easily. Further an evaluation of each theory has also been provided along with the discussion. This note includes the following five welfare economic theories.
1) Pareto Optimality;
2) Kaldor-Hicks Compensation Criterion;
3) Social Welfare Function of Bergson and Samuelsson;
4) Scitovisky Criterion; and
5) Amartya Sen’s Theory of Welfare.

Chapter Summaries
Introduction: This chapter introduces the fundamental concept of welfare economics, emphasizing the importance of cooperation, trust, and the maximization of social welfare. It highlights the subjective nature of welfare and the complex social, economic, political, and psychological issues it encompasses. The chapter establishes the context for the subsequent analysis of various welfare economic theories and positions welfare economics as an integral aspect of a democratic society focused on rational resource allocation and potentially wealth redistribution through taxation or legislation.
Theories of Welfare Economics: This chapter presents an overview of diverse perspectives within welfare economics, emphasizing the lack of a universally accepted method for measuring social welfare. It introduces two major schools of thought: the Paretian approach, which prioritizes improvements that benefit at least one individual without harming others, and the approach of Samuelsson and Bergson, which allows for interpersonal comparisons of utility through a "Social Welfare Function" and considers welfare improvements even if they come at the cost of some individuals. The chapter lays out the five specific welfare theories which are examined in more detail in subsequent chapters.
Pareto Optimality: This chapter delves into Pareto's influential theory, highlighting its significance as a necessary condition for social welfare but also its limitations. The discussion centers around the absence of value judgments, the impossibility of interpersonal utility comparisons, and the complexities that arise when some individuals benefit at the expense of others. The chapter uses a diagrammatic representation involving indifference curves to explain the theory's application and limitations. A critical evaluation section points out the theory's inability to address situations where welfare improvements for some individuals result in welfare declines for others, especially in scenarios involving wealth redistribution. It also notes the theory's failure to identify a maximum social welfare level and the critique by Amartya Sen regarding its potential to overlook extreme inequalities within society.
