Linked Employer-Employee Data from the IAB (LIAB): Working Tools

Dataset Descriptions

All details on variables as well as frequency tables of the different LIAB versions are included in the respective FDZ Datenreports:

An English outline can be found in Schmollers Jahrbuch. 

Test Data

Test data help to prepare programs ahead of on-site and remote data access. They are freely accessible over the web and therefore have to be anonymised. They shall reflect the structure of the original data as close as possible to be useful for many kinds of different analyses. As there are no universally useful test data we suggest that you adjust the test data for your purposes, e.g. if Spanish employees are in the focus of your investigation, just recode enough nationalities to Spanish.

TEST DATA ARE RANDOM AND THEREFORE NOT ELIGIBLE FOR ANALYSIS!

Unfortunately, there are not completely suitable test data for the LIAB longitudinal models. We recommend to use the test data of the mover model, which are closest to the LIAB longitudinal models.

Test data for Stata:

• Test data LIAB cross-sectional model 2 (1993-2010)
• Test data LIAB cross-sectional model 2 (1993-2008)
• Test data LIAB cross-sectional model (1993-2005)
• Test data LIAB cross-sectional model (1993-2002)
• Test data LIAB mover model (1993-2008)

Other Working Tools

• The establishment part of the LIAB data is the IAB Establishment Panel - see "Working tools for the IAB Establishment Panel"
• A recommendable Introduction is given by FDZ Methodenreport 01/2008: Das IAB-Betriebspanel – von der Stichprobe über die Erhebung bis zur Hochrechnung [The IAB Establishment Panel - Sample, Survey and Weighting]
  Here you will find a detailed description of  the IAB Establishment Panel including information on the establishment number and the linkage quality.
