 The Arrovian framework, however, does not present the ideal environment in which to study minimal liberty. An agent may have the right (or in Hohfeldian terms a privilege) to determine a social decision. Typically, though, he need not exercise his right. Or the agent may be willing to trade or waive his right in exchange for some benefit. Gibbard [1974] argued that the power to waive one’s rights undermined Sen’s claim. Subsequent authors then reformulated Sen’s argument within a more suitable, game theoretic framework. See, e.g., Deb, Pattanaik and Razzolini [1997]. The conflict thus persists in a more plausible and appealing formal framework.
