We consider a pure exchange overlapping generations economy with finitely many commodities and consumers per period having possibly non-complete non transitive preferences. We provide a geometric and direct proof of the Balasko-Shell characterization of Pareto optimal allocation. To avoid some...

This paper offers an integrated view of the relationships between health spending, medical innovation, health status, growth and welfare. Health spending triggers technological progress, which is a potential source of better outcomes in terms of longevity and quality of life, a direct source of...

It is well known that pay-as-you-go retirement programs reduce steady-state welfare and the capital stock in dynamically efficient overlapping generation (OLG) economies. The common two-period OLG model obscures, however, the relationship between the magnitude of these effects and the ages at...

Existing forecasts of a continuously rising income share of health spending (SHS) take per capita income growth and population aging as given. We develop a human capital-based endogenous growth model treating these variables as endogenously determined. In this private-economy setting, SHS has...

This paper considers dynamic optimal income, education, and bequest taxes in a Barro-Becker dynastic setup. Parents can transfer resources to their children in two ways: First, through education investments, which have heterogeneous and stochastic returns for children, and, second, through...

This paper analyzes the impact of demographic change on the sustainability of fiscal policy. Firstly, we study the main causes of the deterioration of Japanese government fiscal conditions from the demographic point of view. Next, we investigate the impact of Korean population aging on the...

Understanding whether the elderly are saving adequately is fundamental to understanding whether elderly households are able to maintain reasonable living standards. One factor that affects wealth accumulation is the extent to which parents need to support children and the extent to which...
