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...

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...

This paper investigates fair (i.e., envy free and efficient) allocations in an overlapping generations economy without production and with two - period lived agents. We show that there exists a conflict between no-envy and efficiency when all generations have identical preferences. This conflict...

This paper studies the constructive nature of social welfare orders on infinite utility streams defined on X= Y^N, satisfying the Pigou-Dalton transfer principle (PD), which are known to be representable (see Alcantud (2010) and Sakamoto (2012)).We describe the restrictions on domain Y for...

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