Whereas existing OLG models with endogenous longevity neglect the impact of environmental quality on mortality, this paper studies the design of the optimal public intervention in a two-period OLG model where longevity is influenced positively by health expenditures, but negatively by pollution...

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...

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 develops an intertemporal model wherein production generates pollution, which is viewed by consumers as a public bad. There are two types of consumer: those who are altruistic and leave bequests to their children, and those who are pure life-cyclers. Both types voluntarily contribute...

This paper studies the determination of public investment in environmental quality when there are private alternatives. Public investment is chosen by majority voting. When consumption and environmental quality are complementary one may observe a solution of the type "ends against the middle".

Abstract This paper applies the analytical tools of optimal taxation theory to the design of the optimal subsidy on preventive behaviours, in an economy where longevity varies across agents, and depends on preventive expenditures and on longevity genes. Public intervention can be here justified...

This study examines the level of public investment in environmental quality when there are private alternatives. Public investment is chosen by majority voting. When consumption and environmental quality are complementary, one may observe a solution of the type “ends against the middle.” The...
