Angesichts hoher öffentlicher Schulden stellt sich in einer sozialen Marktwirtschaft nicht nur die ökonomische Frage nach den intergenerativen Verteilungswirkungen der Staatsverschuldung, sondern auch die sozialethische Frage, wie diese Wirkungen die Gerechtigkeit zwischen den Generationen...

Die Sicherung eines zukunftsfähigen Rentensystems ist eines der dringenden Ziele der aktuellen Sozialpolitik. Dabei spielen die Verteilungswirkungen (insbesondere zwischen verschiedenen Generationen) eine ebenso wichtige Rolle wie die allokative Effizienz. In diesem Buch wird ein Konzept...

In der wissenschaftlichen Literatur standen bis dato die Implikationen des demografischen Wandels für die Sozialversicherungen im Fokus. Die Arbeitsmarkteffekte sind bisher nur höchst unzureichend analysiert worden. Die Arbeit stößt in diese Lücke und liefert wichtige und neue Einsichten in...

The paper develops a unified general equilibrium model including savings with overlapping generations, investment and search unemployment. Long-run analytical results for the small open economy identify capital accumulation as a prime transmission channel. The effects of integration on...

The demographic transition is a phenomenon affecting many industrialized societies. These economies are experiencing a decline in mortality alongside low fertility rates - a situation that puts social security systems under severe pressure. To implement appropriate reform measures, adequate...

This book presents a new computational approach to solving large-scale Auerbach-Kotlikoff Overlapping Generations (OLG) models in a complementarity format. Unlike with integrated solution methods, the proposed decomposition algorithm allows for the solution of multi-regional and multi-sectoral...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

The German Income Tax Reform 2000, which announced a reduction in income tax rates to be implemented in a series of three stages, was welcomed by the public as a step towards unleashing lurking growth potentials. Nonetheless, in the course of the year 2001 a dispute arose, centering around the...

This paper investigates the inter-temporal structure of implicit taxes that arise in unfunded pension schemes. We demonstrate that these tax rates are declining over the life cycle. Using German micro-data for men and married women we estimate periodic wage elasticities of labour supply in order...
