(d) Satisfies universal domain and the Pareto criterion, but violates independence of irrele vant alternatives. 4. Arrows theorem states that: (a) If there are three or more alternatives, then any SWFP that satisfies universal domain, the Pareto criterion, and independence of irrelevant alternatives must be a dictatorship.
