This study uses Fehr, Jokisch, and Kotlikoffs̕ (2004a) dynamic general equilibrium model to analyze the effects of changes in fertility and mortality on the developed worlds̕ demographic transition. The model features three regions the U.S., Japan, and the EU-15 and incorporates age- and...

The present paper studies the growth and efficiency consequences of pension funding with individual retirement accounts in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty. We distinguish between economies with rational and hyperbolic...

Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

The present paper quantifies the economic consequences of eliminating the system of income splitting in Germany. We apply a dynamic simulation model with overlapping generations where single and married agents have to decide on labor supply and homework facing income and lifespan risk. The...

The present paper quantifies the importance of family insurance for the analysis of social security. We therefore augment the standard overlapping generations model with idiosyncratic labor productivity and longevity risk in that we account for gender and marital status. We simulate the...

The present paper aims to quantify the welfare effects of progressive pension arrangements in Germany. Starting from a purely contribution-related benefit system, we introduce basic allowances for contributions and a flat benefit fraction. Since our overlapping-generations model takes into...

This paper studies the role of pensions and income taxes in determining homeownership and household wealth. It provides a cross-country analysis, using tax and pension policy designs in Germany, the US and Australia. These developed nations have similar incomes per capita but very different...

This note demonstrates that optimal tax calculations in overlapping generations models should not be based exclusively on long-run welfare changes. As the latter represent a mix of efficiency and intergenerational redistribution effects, they typically favor policies which redistribute towards...

The present paper develops a general equilibrium model with overlapping generations and endogenous fertility in order to analyze the interaction between public policy and household labor supply and fertility decisions. The model's benchmark equilibrium reflects the current family policy...
