Linked-Employer-Employee-Data of the IAB (LIAB)

The Linked-Employer-Employee-Data of the IAB (LIAB) combine interviews from the IAB Establishment Panel with the related establishment and individual data generated in labour administration and social security data processing. The latter cover administrative establishment information from the Establishment History Panel (BHP) and the employment biographies of individuals employed by the interviewed establishments. The LIAB data allow for simultaneous analysis of the supply and demand side of the German labour market.

Data Versions

There are two types of LIAB models:

  • LIAB cross-sectional model: Individual employment biographies depicted on the reference date 30 June are linked with the IAB Establishment Panel. This model includes observations of all individuals employed by an establishment surveyed in the IAB Establishment Panel in the respective year.
  • LIAB longitudinal model: This model includes comprehensive employment biographies of individuals of a subsample of establishments repeatedly interviewed in the IAB Establishment Panel. Therefore, employment biographies can still be tracked in the events of e. g. establishment changes or transitions into unemployment within this subgroup.
