IAB Establishment Panel (restricted access)

Restricted survey microdata: not exercised here

The IAB Establishment Panel is confidential German survey microdata (Institute for Employment Research, IAB). It is not for sale and not publicly downloadable: it carries no provenance badge because there is no access path we can run here. Researchers reach it only through the IAB Research Data Centre (FDZ), on-site or via remote execution, with output subject to disclosure review. The page documents what the collection is and the gotchas; treat it as unverified. This is the honest grade under the institute’s Verified discipline.

The IAB Establishment Panel is an annual, representative survey of German establishments (workplaces), interviewing thousands of establishments each year about employment, hiring and separations, wages, working time, training, investment, business expectations, and internal practices. Because it samples establishments drawn from the social-security universe, it complements the administrative IEB (which has the worker spells but not the survey questions on practices and expectations). A paper we distill uses it: Bias, Lochner, Obernberger & Sevilir use the IAB Establishment Panel to test whether the hierarchical changes they measure correlate with the formalization of internal processes, alongside the worker-level IEB.

• Cost: not for sale. Restricted survey microdata.
• Producer: Institute for Employment Research (IAB); access via the FDZ.
• Coverage: a representative annual panel of German establishments (the survey began in the western states in 1993 and added the east in 1996), with sampling weights for population inference.

Access (restricted)

• Through the IAB Research Data Centre (FDZ). Approved researchers work on-site at an FDZ guest workstation or via the FDZ remote-execution service (JoSuA); the microdata does not leave the secure environment, and outputs are checked.
• Project approval required. Access requires an approved project and a data-use agreement; data is a project-specific extract, not an open download.
• The FDZ publishes documentation and questionnaires, so the variables can be read even though the data cannot be pulled.

Gotchas (the ones that bite pipelines)

These are the failure modes to expect; they are documented, not verified here.

• It is a survey, so use the weights. Unlike the administrative IEB, this is a sample; population statements require the provided sampling weights, and large establishments are over-sampled by design. Do not treat raw counts as population totals.
• Establishment, not firm. The unit is the establishment (workplace), not the legal firm; a multi-site firm appears as separate establishments or not at all. Do not roll up to the firm without external links.
• Panel attrition and rotation. Establishments enter, drop out, and are refreshed; the panel is unbalanced and attrition is non-random (closures). Model entry/exit rather than assuming a fixed panel.
• Questionnaire changes year to year. Topics rotate and question wording changes across waves; a variable may exist only in some years or shift meaning. Check the questionnaire for each wave you use.
• Self-reported and recall-based. Many items are self-reported by the respondent and refer to a reference date or prior year; they carry recall and reporting error. Cross-check against IEB administrative measures where possible.
• Output is disclosure-reviewed and cannot be redistributed. Results leave the FDZ only after review, and the microdata itself cannot be shared.
