- 1. Social Choice and Individual Values, published by Kenneth Arrow in 1951, is a seminal work in the field of social choice theory and economics that explores the intricacies of collective decision-making processes. In this pioneering book, Arrow introduces what is now famously known as Arrow's Impossibility Theorem, which demonstrates the inherent challenges in designing a fair and rational voting system that accurately reflects individual preferences while adhering to certain desirable criteria, such as unrestricted domain, non-dictatorship, Pareto efficiency, and independence of irrelevant alternatives. Through a rigorous mathematical framework, Arrow articulates how it is fundamentally impossible to formulate a social welfare function that satisfies all of these conditions simultaneously when faced with three or more options, thus highlighting the complexity of aggregating individual values into a cohesive social choice. The implications of Arrow's work extend beyond economics, influencing political science, philosophy, and social sciences, as it raises crucial questions about democracy, fairness, and the nature of collective decision-making. This book not only lays the groundwork for future research in the domain but also challenges readers to think critically about the limitations and possibilities inherent in the mechanisms used to reflect society's preferences.
