Notes on Social Choice Theory

چکیده
Social choice theory is the study of how decisions are made collectively. It examines the idea that, for a given society, the preferences of individuals can be directly aggregated to reflect a quintessential “social preference.” An example of such a preference aggregation method is simple plurality rule, in which citizens vote for a candidate and the candidate winning the most votes is deemed society’s most-preferred. In general, social choice theory does not aim to analyze or predict individual behavior, but rather to compare and evaluate different means of aggregating preferences.
