New

Combining firm datasets of the single data producers for the first time in Germany; time horizon 1993 - 2006 New dataset for researchers with:

  • a variety of variables,
  • a variety of data generating processes
  • a variety of economic sectors

Reduce respondent burden for the firms

Innovative

Four years ago: No possibility to match datasets and also no data exchange between the single data producers Prohibited by law Today: Change of the Federal Statistics Act Matching is (technical) possible Combined Firm Data are unprecedented until KombiFiD

KombiFiD - approach

Federal Data Protection Act: match data with a written agreement only „Survey“: 60.000 firms Only one question Matching ... the data of firms, which gave their written agreement

Our Challenges

Unit non-response: Number of answering firms? Matching difficulties: Datasets with different levels of aggregation! (establishment, firm) Data consistency Legislative initiative

Three ways of data access

On-Site Use: At this researchers may analyze weakly anonymous data at separate workplaces for guest researchers during a research visit. Remote Data Access: Therefore researchers develop programs on the basis of test data. These programs are run through the original data at the research data centre. After verification of compliance with data protection legislation the results are sent to the researcher. Scientific Use Files: This are factually anonymous datasets offered for researchers of scientific institutions for analysis.
