We present an OLG model in which life expectancy and environmental quality dynamics are jointly determined. Agents may invest in environmental care, depending on how much they expect to live. In turn, environmental conditions affect life expectancy. As a result, our model produces a positive...

We develop a simple overlapping generations model to analytically show that population aging leads to increased educational efforts through a general equilibrium effect. The key mechanism at work in the model is that scarcity of raw labor increases the rate of return to human capital relative to...

This paper sets up an OLG economy with endogenous life expectancy to study how fiscal policy that redistributes between generations can open the door to sunspot equilibria. Agents invest independently in their own human capital, produce and consume output, and receive a pension upon retirement....
