This paper studies the optimal design of assisted reproductive technologies (ART) policies in an economy where individuals differ in their reproductive capacity (or fecundity) and in their wage. We find that the optimal ART policy varies with the postulated social welfare criterion....

Nozick's "utility monster" - a being who is more efficient than other persons at transforming resources into well-being - is often regarded as deeply impossible, on the ground of the incapacity of a single person to have a life that is better than a large number of other lives. In this article,...

This paper re-examines the spaceship problem, i.e. the design of the optimal population under a fixed living space, by focusing on the dilemma between adding new beings and extending the life of existing beings. For that purpose, we characterize, under time-additive individual welfare depending...

This paper re-examines the spaceship problem, i.e. the design of the optimal population under the environmental constraint of a fixed area available for life, by focusing on the dilemma between adding new beings and extending the life of existing beings. For that purpose, we characterize, under...
