Linking the Mannheim Enterprise Panel (MUP) with Administrative Establishment Data of IAB – an update

Abstract

"This report describes the update of the key between establishment and enterprise identifiers. This key enables the combination of administrative employment data of the Institute for Employment Research (IAB) with external enterprise data that has a Creditreform or Moodys (former Bureau van Dijk) identifier for the years 1993 to 2022. To establish this combination, we performed a record linkage between the address data of the IAB and the address data of the Mannheim Enterprise Panel (MUP) hosted at the Leibniz Centre for European Economic Research (ZEW). This report describes the record linkage process, present quality and repre-sentativeness checks and also discusses limitations of the data. The key will be the base of standard data products that will be available via the Research Data Centre of the IAB (FDZ). Moreover, the presented key allows to generate customized data sets."
