Hirings in the IAB Job Vacancy Survey and the administrative data - an aggregate comparison

Abstract

"In this FDZ method report, we compare the number of hirings measured by the IAB-Job Vacancy Survey (IAB-JVS) with the number of hirings calculated from a sample from the Integrated Employment Biographies (IEB). To this end, we attempt to identify potential important differences in measurement concepts, by conducting a comparison of the aggregate number and structure of hirings in the IAB-JVS and the IEB. Specifically, we explore whether hirings with specific characteristics are systematically over- or underreported by the respondents in the IAB-JVS. As this approach requires knowledge about the composition of hirings, we complement the survey data, by using the record linkage of IAB-JVS information on the last hired person to his or her administrative records from the IEB. We first document that the IAB-JVS provides a systematically lower number of hirings as compared to the IEB throughout our observation period. Our results further suggest that a large part of the established discrepancies between the IAB-JVS and IEB hirings arise from respondents underreporting recalls and very short employment relationships. In addition, supplementary results suggest that missing information in response to the question on new hires is responsible for an additional part of the underestimation."
