This paper reviews the welfarist approach to population ethics. We provide an overview of the critical-level utilitarian population principles and their generalized counterparts, examine important properties of these ...
A Characterization of Consistent Collective Choice Rules
(Université de Montréal. Département de sciences économiques., 2006-08)
We characterize a class of collective choice rules such that collective preference relations are consistent. Consistency is a weakening of transitivity and a strengthening of acyclicity requiring that there be no cycles ...
Infinite-Horizon Choice Functions
(Université de Montréal. Département de sciences économiques., 2006)
We analyze infinite-horizon choice functions within the setting of a simple linear technology. Time consistency and efficiency are characterized by stationary consumption and inheritance functions, as well as a transversality ...
