This paper studies the nature of social welfare orders on infinite utility streams, satisfying the efficiency principle known as Monotonicity and the consequentialist equity principle known as Strong Equity. It provides a complete characterization of domain sets for which there exists such a...

We study two related versions of the no-impatience postulate in the context of transitive and reflexive relations on infinite utility streams which are not necessarily complete. Both are excluded by the traditional (weak) anonymity axiom. We show explicit social welfare relations satisfying...

This paper studies the nature of social welfare orders on infinite utility streams, satisfying the consequentialist equity principles known as Hammond Equity and Pigou-Dalton transfer principle. The first result shows that every social welfare order satisfying Hammond Equity and the Strong...

An anonymous social choice function for a large atomless population maps cross-section distributions of preferences into outcomes. Because any one individual is too insignificant to affect these distributions, every anonymous social choice function is individually strategy- proof. However, not...

Arrow's Impossibility Theorem is commonly understood to invoke a dictatorship that is somehow lurking within our voting arrangements. A well-recognized statement of the theorem is that "any constitution that respects transitivity, independence of irrelevant alternatives and unanimity is a...

In this paper we show that if the Pareto relation is acyclic then the set of all Pareto optimal social states coincides with chosen social states of acyclic Paretian social welfare relations. Subsequently we show that given an acyclic Paretian social welfare relations the set of all social...

This paper develops an expanded framework for social planning in which coercion stemming from the provision of public goods is explicitly acknowledged. Key issues concern the precise definition of coercion, its difference from redistribution, and its incorporation into social welfare...
