Abstract
One of the paradoxes in the theory of collective choice that has caused considerable concern among scientists both in economic theory and philosophy is that of the “impossibility of the Paretian liberal” which was discovered by Sen (1970 a; 1970 b, chapter 6). It has been found troublesome that even a minimal amount of efficiency, as expressed by the Pareto principle, appears to be incompatible with a weak libertarian requirement, viz. providing each member of society with a small “protected sphere”.KeywordsSocial ChoicePreference ProfilePareto PrinciplePareto RuleUnconditional PreferenceThese keywords were added by machine and not by the authors.
