Notes on Effective Freedom
This paper presents an intuitive approach for comparing opportunity sets in freedom they offer. The decision maker faces a range of scenarios, here modeled as a collection of possible preference orderings over alternatives. One set is said to have greater effective freedom if, for each preference ordering, it contains an alternative that dominates all the alternatives in the second set. The properties of the effective freedom ranking are explored and various full and partial representations are presented. A key example is provided that shows how the effective freedom relation can rank sets even when the preference orderings strongly disagree with one another. Depending on the collection of preferences, the approach can generate the indirect utility ranking, for which unchosen alternatives have no value, or the Pattanaik and Xu (1990) cardinality ranking, in which every alternative has the same intrinsic value.
