Abstract This article aims at investigating the interplay between environmental quality, health, and economic development in a unified OLG framework. Human capital accumulation depends on the environment through its impact on children's health and workers' productivity. In turn, environmental quality dynamics rely upon human capital that determines maintenance efforts. This two‐way relationship generates a co‐evolution of human capital and environmental quality in the long run. Along the transition path, the dynamic interactions between economic and environmental spheres allow for replicating two different trajectories: some economies experiment an Environmental Kuznets Curve while some others are caught into the environmental poverty trap.

Résumé Cet article explore une nouvelle relation qui associe la santé, la qualité environnementale et le développement économique. Nous considérons un modèle à générations imbriquées, où le capital humain des travailleurs dépend des conditions environnementales et des dépenses de santé engagées par les agents. Le modèle induit une complémentarité entre dépenses de santé et conditions environnementales, qui engendre l'existence d'une trappe environnementale. Cette dernière est caractérisée par un niveau de santé faible et de mauvaises conditions environnementales. De plus, le modèle fournit des mécanismes endogènes et rationnels qui peuvent conduire à l'existence de cycles environnementaux, ou à l'effondrement de la qualité environnementale.

It is widely accepted that environmental and demographic changes will significantly influence the future of our society. In recent years, an increasing number of studies has analyzed the interlinkages among economic growth, environmental factors and a specific demographic variable, namely life expectancy, applying an overlapping generations framework. The aim of this survey is threefold. First, we review the role of life expectancy and pollution for sustainable growth. Second, we discuss the role of intervening factors like health investment and technological progress as well as institutional settings including government expenditures, tax structures and inequality. Finally, we summarize policy implications obtained in different models and compare them to each other.

Based on epidemiological evidence, we consider an economy where agents differ through their ability to procreate. Households with impaired fertility may incur health expenditures to increase their chances of parenthood. This health heterogeneity generates welfare inequalities that deserve to be ruled out. We explore three different criteria of social evaluation in the long-run: the utilitarian approach, which considers the well- being of all households, the ex-ante egalitarian criterion, which considers the expected well-being of the worst-off social group, and the ex-post egalitarian one, which only considers the realized well-being of the worst- off. In an overlapping generations model, we propose a set of economic instruments to decentralize each solution. To correct for the externality and inequalities, both a preventive (a taxation of capital) and a redistributive policy are required.
