Inequality averse collective choice

    Research output: Contribution to journalArticlepeer-review


    The Lorenz-Pareto optimal frontier of a collective choice problem identifies a subset of all Pareto optimal outcomes which are not inegalitarian according to the Lorenz criterion. An inequality averse choice function must thus be Lorenz-Pareto optimal in the sense that it should never 'choose' an outcome outside the Lorenz-Pareto frontier of any choice problem. We study the basic properties of the Lorenz-Pareto optimal choice functions and, in particular, obtain necessary and sufficient conditions for rationalizability and representability of such choice functions. Several applications to the theory of Nash bargaining are also outlined.
