This paper explores the properties of several notions of efficiency (A−efficiency, P−efficiency and Millian efficiency) to evaluate allocations in a general overlapping generations setting with endogenous fertility and descendant altruism that includes, as a particular case, Barro and...

This paper studies an extension of the notion of Pareto eciency, referred to as Millian eciency, to evaluate the performance of symmetric allocations in an overlapping generations setting with endogenous fertility. The criterium of Pareto dominance underlying the notion of Millian eciency is...
