An introduction to modern welfare economics

Abstract

This work explores foundational concepts in welfare economics, including Pareto optimality within market economies, the compensation principle, and social welfare functions. It analyzes market failures using various methods for measuring welfare changes. Additionally, it delves into public choice theory, addressing the provision of public goods, median voter equilibrium, potential government failures, efficient and optimal taxation strategies, and issues of intergenerational equity. The concluding sections focus on applied welfare economics, covering methodologies for eliciting public preferences, the principles and practice of cost-benefit analysis, and techniques for evaluating projects under conditions of risk.
