"This paper examines the effect of the introduction of permanent benefit reductions for early retirees (i) on the duration until benefit claiming and (ii) on the duration until exit from gainful employment. I estimate discrete time duration models using different error term specifications. Administrative data containing the full earnings history of the individuals are used. Since the reform implementing the benefit reductions was a natural experiment, under some assumptions a causal effect can be identified. The permanent reduction of retirement benefit amounts causes a postponement of claiming benefits by about 14 months and a delay of employment exit by about 10 months on average."
