Endogenous lifetime in an overlapping generations small open economy

Using a simple overlapping generations small open economy, we show that endogenous longevity - through public health expenditure - may reduce both the saving rate and per capita domestic income, while increasing the per capita foreign debt in a country. Moreover, despite funding public health capital is always beneficial for life expectancy, it may or may not represent a Pareto improvement with respect to the laissez-faire solution depending on whether the world interest rate is high or low enough, respectively.
