Effects of the statutory minimum wage on the pensions provided by statutory pension insurance

The goal of the research project is to clarify the impact of the statutory minimum wage on pensions. A simulation model will be used to calculate the effect of the introduction of the minimum wage on central pension values. The two main questions the research program addresses are the following: 1) How has the statutory minimum wage affected the adjustment of the current pension value and the different factors in the pension adjustment formula? 2) Do the effects differ across socio-demographic groups, forms of employment or geographic regions?

The potential usefulness of administrative statistics for evaluating the statutory minimum wage

The aim of the research project is to assess the potential value of German administrative data at the firm level as a tool for evaluating the statutory minimum wage. The relevant data are the German Administrative Data-Firm Level (AFiD) and the Combined Firm-Level Data for Germany (KombiFiD). The research project will clarify the accessibility of the data for periods before and after the introduction of the minimum wage and assess whether panel data or cross-sectional data are available.
