Birth-date dependent population ethics: critical-level principles.
"This paper investigates birth-date dependent principles for social evaluation in an intertemporal framework in which population size may vary. We weaken the strong Pareto principle in order to allow individuals' birth dates to matter in establishing a social ordering. Using the axiom independence of the utilities of the dead, we characterize population principles with a recursive structure. If the individual substitution principle and an individual intertemporal equivalence axiom are added, birth-date dependent generalizations of the critical-level generalized utilitarian principles result. Stationarity leads to the special case of geometric discounting."

Leximin population ethics.
This paper concerns the ethical issues that arise when policy decisions have to be taken that affect population size and characteristics. Such policies include social security systems, intertemporal resource allocation decisions, and policies designed to influence fertility rates. The authors provide characterizations of Leximin principles for social evaluation in an intertemporal framework, so that they can be used to compare social alternatives with different population sizes. "The main axioms used in our characterizations are Hammond Equity together with Independence of the Utilities of the Dead (a plausible intertemporal consistency requirement) for the Critical-Level Leximin principles, and Positional Leximin Consistency (an axiom that allows non-constant critical levels) for the Positional-Extension Leximin principle. The performance of these principles is compared in the pure population problem and we argue that the Critical-Level Leximin principles are ethically more attractive than Positional-Extension Leximin."

Intertemporal population ethics: critical-level utilitarian principles.
"This paper considers the problem of social evaluation in a model where population size, individual lifetime utilities, lengths of life, and birth dates vary across states. In an intertemporal framework, we investigate principles for social evaluation that allow history to matter to some extent. Using an axiom called independence of the utilities of the dead, we provide a characterization of critical-level generalized utilitarian rules. As a by-product of our analysis, we show that social discounting is ruled out in an intertemporal welfarist environment. A simple population-planning example is also discussed."
