We investigate welfare and aggregate implications of a pay-as-you-go (PAYG) social security system in a dynastic framework in which individuals have self-control problems. The presence of self-control problems induces individuals to save less because of their urge for temptation towards current...

In this paper we develop a stochastic dynamic general equilibrium overlapping generations (OLG) model with health as a durable good to study the life-cycle behaviors of health care spending and financing. We show that a calibrated version of our generalized Grossman model is able to match the...

We study optimal income tax progressivity in an environment where individuals are exposed to idiosyncratic income and health risks over the lifecycle. Our results, based on a calibration for the US economy, indicate that the presence of health risk combined with incomplete insurance markets...

We study the incidence of capital income taxation in a dynamic general equilibrium model with heterogeneous firms and lifecycle households. In this incomplete market setting, marginal excess burdens of three capital taxes, namely corporate income, dividend and capital gains taxes, are vastly...

Inclusion of means testing into age pension programs allows governments to better direct benefits to those most in need and to control funding costs by providing flexibility to control the participation rate (extensive margin) and the benefit level (intensive margin). The former is aimed at...
