preference over preferences. In addition to having a preference over outcomes, the agent likes a preference if she prefers behaving as if she holds that preference:
preferring \(x\) to \(y\)is preferred to
preferring \(y\) to \(x\)if she values the act of willingly giving up \(y\) for \(x\) more than giving up \(x\) for \(y\). I show that a preference over the acts of choosing has a unique representation that identifies the agent's second-order preference, which induces any standard menu preference in the literature. Unlike how outcomes are ranked, the value of preferences is relative to contextual factors; consequently, the best act of choosing may only be possible when the best outcome is not available—contrary to common conjectures in prior work. I discuss how these preferences can be observed. My model also accommodates preferences over others’ preferences, offering a theoretical advance toward resolving paternalistic decision problems when choices may not reveal welfare.
