This paper develops an overlapping-generations model characterized by endogenous growth, unemployment, and pollution. The paper focuses on the replacement ratio, which measures the proportion of after-tax work earnings replaced by unemployment benefits, and considers a replacement-ratio-neutral...

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 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. In...

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 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...

In the real world, two types of education investment may exist. One of these contributes to labor skills, and the other does not, corresponding to human capital and signal invest- ment, respectively. The question is how individuals determine the ratio of these alternative investments. In...

We consider a two-period overlapping generations model where agents face the uncertainty of intergenerational transfers from their children. To avoid this kind of risk, agents have an incentive to share the risk within the same generation. However, there exists an information asymmetry about the...

In this paper, we use a two-period overlapping generations model to examine the behavior of an economy that incorporates intergenerational transfers of time. In the first part, we describe the dynamics and steady state of the economy in which there is no government. We show that the rate of life...

Using an overlapping generations model, this note shows that an improvement in the efficiency of human capital production decreases the net income of the young household while increasing that of the old. Without compensating redistribution, it deteriorates lifetime utilities of all generations...
