Essential alternatives and freedom rankings
نویسندگان
چکیده
We study the problem of ranking opportunity sets in terms of freedom of choice. The analysis is based on the notion of essential alternatives introduced in Puppe (1996). An alternative in an opportunity set is called essential if by deleting it, the reduced opportunity set offers less freedom than the original set. We provide an axiomatic characterization of the ranking according to which an opportunity set offers more freedom than another opportunity set if its share of essential elements in their union is larger.

Due to its universality, voting among a set of alternatives has a central role among preference aggregation mechanisms. We consider the most general case of voting in which the voters’ rankings of alternatives are mapped to a collective ranking of alternatives by a so-called social welfare ...
متن کاملThe specific value of freedom
This article examines the question of how to assess our overall freedom in terms of its so-called specific value, i.e., the part of its value that can be reduced to the value of the various specific thingswe are free to do or be. It is argued that existing preference-based freedom rankings may fail to capture this value adequately and, drawing on earlier work by Puppe (J Econ Theory 68:174–199,...
