We study interactions between progressive labor taxation and social security reform. Increasing longevity puts fiscal strain that necessitates the social security reform. The current social security is redistributive, thus providing (at least partial) insurance against idiosyncratic income...

We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We introduce a...

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...

Pay-as-you-go (PAYG) social security schemes in the OECD countries are facing solvency problems, as people are living longer and birth rates have declined. Postponing the full retirement age (FRA), when retirees are entitled to full pension, has been proposed as a solution. This effectively...

This paper presents a classical model of economic growth which incorporates class conflict and induced technological change to show how demographic changes can affect future income distribution and production relations in industrialized countries. Specifically, I use an extended real wage...

For most households in the U.S., the largest proportion of net worth is owner-occupied housing. We show that incorporating frictions associated with housing market into the life cycle framework generates a long-run welfare gain of eliminating social security almost twice as much as in a standard...

We quantify the importance of idiosyncratic health risk in a calibrated general-equilibrium model ofSocial Security. We construct an overlapping-generations model with rational-expectations households,idiosyncratic labor income and health risk, profit-maximizing firms, incomplete insurance...

This paper investigates the fiscal pressure from demographic change in relation to the labour marketspace for fifty countries that cover 75% of the world population. The pressure-to-space indicator ranks Poland, Turkey and Greece high. Apart from Turkey and India, developing countries rank low...

This study compares alternative designs of an unfunded pension system. Convex combinations between a fixed contribution rate and a fixed benefit rate are considered. The objective is to maximize the expected ex-ante welfare under stochastic fertility. The model is a three-period CGE framework...
