Kenneth Arrow's
monograph Social Choice and Individual Values (1951, 2nd ed., 1963) and a theorem within it created modern
social choice theory, a rigorous melding of social
ethics and
voting theory with an
economic flavor. Somewhat formally, the "social choice" in the title refers to Arrow's representation of how
social values from the
set of individual orderings would be implemented under the
constitution. Less formally, each social choice corresponds to the feasible set of laws passed by a "vote" (the set of orderings) under the constitution even if not every individual voted in favor of all the laws.
