This book addresses the gaps in undergraduate teaching of partial equilibrium analysis, providing a general equilibrium viewpoint to illustrate the assumptions underlying partial equilibrium welfare analysis. It remains unexplained, at least at the level of general economics teaching, in what sense partial equilibrium analysis is indeed a part of general equilibrium analysis. Partial equilibrium welfare analysis isolates a market for a single commodity from the rest of the economy, presuming that other things remain equal, and measures gains and losses by means of consumer surplus. This is a money metric that is supposed to be summable across individuals, recommending policy that maximizes the social surplus. But what justifies such apparently uni-dimensional practise? Within a general equilibrium framework, the assumption of no income effect is presented as the key condition, and substantive general equilibrium situations in which the condition emerges are presented. The analysis is extended to the case of uncertainty, in which the practice adopts aggregate expected consumer surplus, and scrutinizes when such practice is justified. Finally, the book illustrates partial equilibrium as an institutional artifact, meaning that institutional constraint induces individuals to behave as if they are in partial equilibrium. This volume forms an important contribution to the literature by researching why this disparity persists and the implications for economics education.

This textbook covers microeconomic theory at the level of intermediate and advanced undergraduates. It is also intended as an introduction for those with other intellectual and academic backgrounds who may not necessarily agree with "mainstream" economists but at least are interested knowing how they think and see things. The book provides thorough explanations of definitions and assumptions that the theory is based upon. It provides comprehensive accounts of motivations and reservations behind the theory. As well, it precisely presents the logical process of how the assumptions lead to the conclusion, conveying the intuition and the key of the arguments. An abundance of topics is included here: individual choice, general equilibrium, partial equilibrium, game theory, imperfect competition, transaction under incomplete information, market failures, welfare economics, social choice and mechanism design. The book is a valuable resource for any reader studying or simply interested in microeconomic theory.
