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...

We study the interplay between tenure decisions, stock market investment and the public social security system. Housing equity not only serves a dual purpose as a consumption good and as an asset, but also provides insurance to buffer various risks in retirement. Our life cycle model captures...

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...

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...

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...
