From the “designer perspective,” we explore which rules should be put in place by the authority (the “designer”) orchestrating a set of agents. The main goal of this unit is to formulate the concepts and models of social choices.
This unit is organized into three sessions. In the first section, we discuss the most familiar voting scheme, plurality. Then we look at the formal model of social choice theory, consider other voting schemes, and present two seminal results about the sorts of preference aggregation rules that it is possible to construct. Finally, in the last section, we consider the problem of building ranking systems, where agents rate each other.
