Kick-off meeting in Frankfurt (April 1st, 2011):
All scientific researchers who are interested in the KombiFiD data are invited to a kick-off meeting at the Goethe-University Frankfurt. For further information klick here (only in German).
First details about the data linkage:
This report presents the first results of the linkage of the Establishment-History-Panel (BHP) of the Institute for Employment Research (IAB) and the German Business Register System (URS) of the German Statistical Offices. As first analysis show that the Establishment-History-Panel (BHP) includes a very high rate (over 90%) of completely identifiable firms registered in the German Business Register System (URS) the KombiFiD dataset offers high analysis potential regarding differentiated longitudinal section.

First detailed description of the KombiFiD sample selection as well as specific information about the response rate:
The following report presents for the first time a detailed description of the KombiFiD sample selection as well as specific information about the response rate. The KombiFiD sample consists of subsamples with a final sample size of 54.960 firms. A continuously increasing number of firms agreed to the combination of datasets by different producers during the survey period (April to August 2009). After the first survey phase (29 April) the agreement rate was 17.8%, the response rate 27.6%. Two reminders were send, the first leading to an agreement rate of 24.9% (response rate: 43.6%) and the second to an agreement rate of 29.6% (response rate: 55.6%).
Further information about the sample selection and the response rate can be found in the following report:
