We develop an overlapping generations model of growth and the environment in which industrial firms produce environmentally harmful emissions. A government controls the emissions by assigning emission quotas to firms, and permits could be issued and freely traded as financial instruments across...

This paper develops a two-period overlapping-generations model with environmental externalities and uncertain lifetimes, and studies how two sources of population aging, greater longevity and a lower rate of population growth, affect the politically determined environmental tax and the quality...

This paper presents a two-period overlapping-generations model in which (i) firms create environmentally harmful emissions as by-products of production, and (ii) social security tax revenue from the working young is transferred to the retired elderly as pay-as-you go social security benefits.

This paper analyzes a social security policy with public debt in an overlapping generations growth model. In particular, the paper considers a situation in which population aging causes a heavy burden of social security payments where public debt is issued by the government to finance the...

How does aging affect the environment? We analyze this question using anoverlapping generations model featuring uncertain lifetimes andenvironmental externalities. We show that whether aging is harmful to theenvironment depends on the curvature of utility function, which ismeasured by the degree...
