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.
