Wir diskutieren eine Reihe von Problemen der Rentenformel in der deutschen gesetzlichen Rentenversicherung (GRV). Wir zeigen, dass Bev¨olkerungsgruppen mit ¨uberdurchschnittlicher Lebenserwartung, insbesondere die besser Verdienenden, von den ¨ubrigen Versicherten subventioniert werden, da...

We analyze optimal income taxes with deductions for work-related or consumptive goods. We consider two cases. In the first case (called a complex tax system) the tax authorities can exactly distinguish between consumptive and work-related expenditures. In the second case (called a simple tax...

Micro-econometric intra-cohort profitability analyses of pay-as-you-go (PAYG) pension contributions are rare. We use representative employment histories of a birth cohort of German PAYG pension insurants retiring in year 2005 to econometrically examine the determinants of the profitability of...

To counteract the financial pressure emerging in aging societies, statutory pay-as-you-go pension schemes are undergoing fundamental reforms in many Western countries. Starting with cohort 1937, Germany introduced permanent pension deductions for early retirement. This paper examines the...

The life-cycle hypothesis implies that consumption would not decline at retirement. However, several studies found relevant declines in food consumption after retirement for the United States. Others concluded that this contradiction of the life-cycle hypothesis is solved by allowing for broader...

The paper presents a model where public pensions are determined by majority voting. Voters differ by age and income. Moreover, life expectancy increases with income. Depending on the strength of the link between contributions and benefits, and the relationship between income and life expectancy,...

This paper examines the consequences of including the self-employed in the German pay-as-you-go pension system. The effects on the implicit tax rate of the different generations and groups are analysed. It is demonstrated that the inclusion of the self-employed can be used to reach two...

In several OECD countries, public pay-as-you-go financed pension systems have undergone major reforms in which future retirement benefit promises have been scaled down. A consequence of these reforms is that especially in countries with a tight tax-benefit linkage, the retirement benefit claims...

We analyze the impact of changing employment patterns and pension reforms on the future level of public pensions across birth cohorts in Germany. The analysis is based on a rich dataset that combines household survey data from the German Socio-Economic Panel Study (SOEP) and process-produced...

The empirical relationship between income and longevity has been addressed by a large number of studies, but most were confined to men. In particular, administrative data from public pension systems are less reliable for women because of the loose relationship between own earnings and household...
