Verteilungswirkungen anreizorientierter Sozialpolitik : das deutsche Rentenversicherungs- und Steuersystem in der Perspektive dynamischer Lebenszyklusmodelle

Grub, Martin - 2005

Drei große Reformenpakete und eine Reihe kleinerer Begleitmaßnahmen prägen das renten¬politische Erbe der rot-grünen Bundesregierung. Einerseits greifen sie Trends in der Reformpolitik seit Beginn der 90er Jahre auf. So verstärkt die Rentenstrukturreform 2001 beispielsweise die...
