MUP-BHP – Enriching Administrative Establishment Data with Commercial Enterprise Data

The recently established link between the Mannheim Enterprise Panel (MUP), developed by the ZEW – Leibniz Centre for European Economic Research, and the administrative establishment information from the Institute for Employment Research (IAB) provides a novel opportunity to combine enterprise-level information with establishment-level labour market data. The core MUP-data are originally collected by Creditreform e.V., a credit rating agency that shares the data with the ZEW for quality assurance and economic research purposes. The establishment-level information is derived from social security notifications. Both data sources are highly complete and of high quality. Linking the two data sources provides information on both enterprise and establishment characteristics for the majority of active businesses in terms of employment and finance, across a longitudinal time series. This paper describes the linkage, the cleaning steps, and the final data product, and how it can be accessed.
