Project heads: Björn Misselwitz (GQH) and Rainer Schnell (University of Duisburg-Essen)

Three separate databases of apoplectic stroke treatment on different stages of therapy (acute cases, early rehabilitation, rehabilitation) will be linked to analyze the courses of the diseases. The German RLC does the patient-related linkage.

Linkage of the German SAVE study with administrative data from the Federal Employment Agency

Project heads: Prof. Axel Börsch-Supan, Ph.D. (MEA) and Stefan Bender (IAB)

SAVE is a longitudinal study on households' saving and asset choices with a special focus on old-age provision. The study started in 2001 with the support of the German Research Foundation (DFG) and is conducted by MEA (Munich Institute for the Economics of Aging). The ninth wave of the survey (SAVE 2011) was run in cooperation with the IAB (Institut für Arbeitsmarkt- und Berufsforschung) in Nuremberg. The project aims at enhancing the information from the household’s survey with administrative data on the labour market biographies of the respondents and (if applicable) their partner. The linkage will be done by the German RLC. For further information on the SAVE study please visit the MEA website.

Private Equity and Employment

Project heads: Prof. Ernst Maug, PhD, Stefan Obernberger (University Mannheim) and Prof. Jörg Rocholl, PhD (European School of Management and Technology)

The project aims at enhancing the database ‘Capital IQ’ with employment data from the IAB and important indicators about the company performance from Amadeus. Capital IQ is a database created by the Chair of Corporate Finance (Prof. Ernst Maug) which contains data about company takeovers. The linkage with the Establishment History Panel (BHP) of the IAB is done by the German RLC.

Private Equity and Employment

Project heads: Dr. Jutta Günther (IWH) and Philipp Marek (IWH)

Linkage of the IWH-FDI micro database of East German companies with the Establishment History Panel (BHP).

Wage structure and patterns of employment in the energy sector

Project heads: Florian Lehmer and Markus Janser (IAB)

Employment data of enterprises with activities in the field of renewable energies will be identified. To do so, addresses of member organisations and enterprises of the German Renewable Energy Federation (BEE) and the German Wind Energy Association (BWE) are linked to the Integrated Employment Biographies (IEB) of the IAB.

Innovation behaviour, regional clustering and agglomeration effects of the German biotechnology industry

Project heads: Bodo Steiner (University of Southern Denmark) and Dirk Dohse (Institute for the World Economy, Kiel)

An access key for relevant enterprises with activities in the sector of biotechnology needs to be identified and created by linking information about German biotechnology companies freely available on the internet with the Establishment History Panel (BHP).

Occupational health research in epidemiological cohort studies (Aeko)

Project heads: Prof. Dr. Karl-Heinz Jöckel and Prof. Dr. Susanne Moebus (both Essen University Hospital, Institute of Medical Informatics, Biometry and Epidemiology (IMIBE)), Prof. Dr. Nico Dragano (Düsseldorf University Hospital, Institute of Medical Sociology)

The goal of AeKo, a study based on the German Heinz Nixdorf Recall (HNR) cohort study, is to link the study results of consenting respondents with the administrative employment data of the Institute for Employment Research (IAB).

Panel Analysis of Intimate Relationships and Family Dynamics (PAIRFAM)

Project heads: PAIRFAM

The project aims at connecting different subsets of the PAIRFAIM data both cross-sectionally and longitudinally. At the beginning of March 2012, representatives of PAIRFAM and center employees  first met in order to consider how the FDZ could support or take over the work of PAIRFAM. As a first step, the employees of PAIRFAM were trained by the center employees in May 2012. Based on this training, the project members of the PAIRFAM project linked the data on their own. While doing this, they received ongoing counselling and support of the German RLC.

Survey data from the panel study ‘Labour Market and Social Security’ (PASS) linked to administrative data from the IAB

Project heads: Prof. Dr. Mark Trappmann (IAB, University Konstanz)

A linkage of the respondents of the panel study ‘Labour Market and Social Security’ (PASS) to the administrative personal data from the IAB is needed. This is done by the German RLC.

Interactions between realisation opportunities in working life and in private life

Project heads: Prof. Dr. Martin Diewald (University Bielefeld)

In the summer of 2012, 100-120 enterprises have been surveyed within the project ‚Interactions between realisation opportunities in working life and in private life‘. From August to December, 6750 employees of these firms and, if possible, their partners will be surveyed by phone. Provided the interviewed persons agree, the administrative data is to be linked. As the employees of the main survey have been selected from the IAB-data, these persons are linked already. This is not the case for the surveyed partners. For these persons record linkages techniques are applied using names, addresses and birth dates of the partners.

Geocoding of IAB administrative data

Project heads: Prof. Dr. Thomas Bauer (RWI), Prof Dr. Jürgen Schupp (SOEP), Prof. Deborah Cobb-Clark (University of Melbourne) and Dr. Mathias Sinning (Australian National University)

For this project, the administrative data of the IAB has been georeferenced. The aim was to generate new, small-scaled regions depicting neighbourhoods. All persons and enterprises recorded in the Integrated Employment Biographies (IEB) of the IAB at a key date have been linked to the ‘Georeferenzierten Adressdaten Bund’ (GAB) of the Federal Agency for Cartography and Geodesy via the address of residence respectively the address of the enterprise. About 94 percent could be linked successfully. These georeferenced addresses are a useful reference data base for many different aspects of the Record Linkage projects.

Linkage of new migration study of the GSOEP with IEB data from the Federal Employment Agency

Project heads: Prof. Dr. Herbert Brücker (IAB) und Dr. Simone Bartsch (SOEP)

For this project, georeferenced data of people immigrated to Germany after 1992 is needed. Therefore, the German RLC supports the linkage of the new migration study of the GSOEP with IEB data. In a next step around 2500 persons are pooled together in regional groups by using the created geocodes. After an additional onomastic analysis of first and surnames people sorted by regional groups will be interviewed by Infratest.

Record Linkage of administrative patent-inventor data with administrative data on labour market biographies

Project heads: Prof. Dr. Dietmar Harhoff

In joint work with Prof. Harhoff PhD (MPI-IP, Munich), the IAB generates a new research data set that links inventors listed on patents with labour market biography data on German employees.This data allows empirically investigating the micro foundations of innovation and patenting as well as addressing several questions at the intersection of labour market and innovation research.

Pro Kind - A randomized, controlled trial of early childhood intervention in Germany

Project heads: PD Dr. Peter F. Lutz, Prof. Dr. Tanja Jungmann (Leibniz University Hannover)

The project ‘Pro Kind’ gathers data on house-visitation of first-time mothers with financial and social problems. It was carried out between 2006 and 2011 in Lower Saxony, Bremen and Saxony. Specially trained employees, like midwifes or social pedagogue, visited the families starting at two thirds of the pregnancy until the child’s second birthday. A research team of the Leibniz University Hannover evaluated the project by a randomized controlled trial. The control group only receives transportation fees for regular pediatric medical checkup. The number of participants, including the control group, was 755. Data collection for treatment and control group included biannual telephone-interviews, which use the GSOEP as reference survey. Pro Kind tries to improve the families’ economic self-sufficiency by helping parents to develop a perspective for their future. For further information on Pro Kind please visit the project’s website.

The linkage of survey data from consenting project participants with data from the Institute for Employment Research (IAB) will be done by the German RLC.
