Abstract

The COVID 19 pandemic has severely changed the operational reality of establishments in 2020. Establishments have had to close, the instrument of short-time work has been used and the proportion of employees working from home has risen sharply. All these factors may also have influenced the response behavior of establishments, resulting in a selective net sample. In this project, we investigate nonresponse bias in the IAB Establishment Survey (Q1-Q3/2020) and evaluate whether the current weighting procedure can reduce nonresponse bias or should be improved.
