This paper presents an infinite-horizon version of intergenerational utilitarianism that is both satisfactorily complete and consistent. By studying discounted utilitarianism as the discount factor tends to one, we obtain a welfare criterion --- limit-discounted utilitarianism --- that combines...

This paper provides axiomatic descriptions of social welfare relations, defined on infinite streams of utility, that are consistent with the utilitarian criterion on subsets where maximizing aggregate utility has a clear interpretation: the streams, or their differences, are summable. Besides...

It has been known that, in aggregating infinite utility streams, there does not exist any social welfare function, which satisfies the axioms of Pareto, inter-generational equity and continuity. We show that the impossibility result persists even without imposing the continuity axiom. Hence, the...

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...

The paper examines the problem of aggregating infinite utility streams with a social welfare function which respects the Anonymity and Weak Pareto Axioms. It provides a complete characterization of domains (of the one period utilities) on which such an aggregation is possible. A social welfare...

This paper examines the representation and explicit description of social welfare orders on infinite utility streams. It is assumed that the social welfare orders under investigation satisfy upper asymptotic Pareto and anonymity axioms. We prove that there exists no real-valued representation of...

This paper studies the nature (representation and construction) of social welfare orders on infinite utility streams, satisfying strong equity and anonymity. We show: 1) there does not exist a social welfare function satisfying the axioms of Anonymity, Monotonicity and Strong Equity for every...
