The IAB Establishment Panel was launched to obtain information on the demand side of the labor market. This data meets two requirements: providing high quality data for the scientific aims and having an information system for policy makers and practitioners. As it started in 1993 a rich data set of 20 years establishment survey is available now. This article provides information about methodological issues of sample design and data sampling and changes that have taken place in recent years. We focus on quality issues, efforts to improve the survey and on some ongoing discussions about methodological adjustments of the survey mode. 1 The IAB establishment panel 20 years ago the first wave of the IAB Establishment Panel 1 was launched in West Germany after a period of extensive conceptual work and testing. Declared objective of this undertaking was to establish a comprehensive dataset on the demand side of the labor market. From the beginning the project had to meet two requirements: generating high quality data with high analytical potential for the scientific community and providing an information system for policy makers and practitioners. DasFrom this some essentials for the kind of data asked for emerged:-Coverage of all sectors and establishment sizes -Topicality and fast availability of the data -Longitudinal data for causal analysis -High response rates especially among the repeatedly questioned establishments -Dynamic panel that mirrors structural changes in the economy.The twofold orientation towards scientific research and policy making presents a permanent challenge for the annual revision of the questionnaire. The task is to balance the obligation to provide a wide range of unaltered questions each year to enable panel analysis and the need for up to date information on recent topics of labor market policy.1 From the beginning the IAB Establishment Panel has been conducted by TNS Infratest. This paper complements existing papers on the IAB Establishment Panel, especially the 2009 article by Fischer et al. to which some references will be made here. After five years an update of the methodological basics and developments is asked for particularly in a special issue of this journal dedicated to that data set.While providing a comprehensive overview of the methodology (the sample design and sampling process, the survey methodology, the data processing and weighting) we focus on the data sampling process and the measures taken to assure a high data quality. We also pay special attention to the changes that have taken place since 2007 which was the last wave covered by the 2009 article by Fischer et al. (2009).A specific feature of the IAB Establishment Panel is the (main) funding by the German Federal Employment Agency. Therefore, the money is coming from the contributors to the social security system. Additional financial resources come from the federal states (Bundesländer) to carry out state-specific supplementary samples. In 2012 13 out of 16 federal governments took part in the project and pa...

In diesem Beitrag werden -wie schon in den letzten Jahren q -aktuelle Ergebnisse zur Tarifbindung und betrieblichen Interessenvertretung präsentiert. Die Befunde basieren auf Daten des Betriebspanels des Instituts für Arbeitsmarkt-und Berufsforschung (IAB-Betriebspanel), das als einzige repräsentative Datenquelle entsprechende Auskünfte in einer langen Zeitreihe für die Gesamtwirtschaft liefert.

German employment relations are characterized by a distinct dual system. First, working conditions and wages are determined by industry-level collective bargaining agreements. Second, on the establishment-level, the works council is responsible for employer-employee negotiations. However, since the mid-1980s, an increasing number of areas of regulation have been transferred from the industry-to the establishment-level using so-called opening clauses. The analysis in this article relies on rich German establishment data and reveals new insights into the institutional machinery of wage bargaining. While the existence of such clauses is related to higher wages, their application results in wage cuts of roughly the same size. The results also suggest that works councils, on average, are able to prevent the negative wage effects of opening clauses.

Mit diesem Beitrag wird die jährliche Berichterstattung zur Tarifbindung und betrieblichen Interessenvertretung mit Daten für 2020 fortgesetzt. Zunächst wird die Tarifbindung der Betriebe nach Branche und Betriebsgröße dargestellt. Dabei wird auf die nach wie vor vorherrschenden Unterschiede zwischen West- und Ostdeutschland abgestellt. Insgesamt jedoch hat die Flächentarifbindung seit 1996 in beiden Landesteilen eine deutlich rückläufige Tendenz. Auch für die betriebliche Ebene der Mitbestimmung ist in der langen Sicht ein abnehmender Deckungsgrad zu konstatieren. Allerdings deutet sich für Ostdeutschland zuletzt eine Trendwende und damit eine Annäherung an westdeutsche Verhältnisse an. Abschließend wird in der gemeinsamen Betrachtung der betrieblichen und sektoralen Ebene der Interessenvertretung auf die ausgedehnten betrieblichen Vertretungslücken sowie die „weißen Flecken“ in der Tarif- und Mitbestimmungslandschaft hingewiesen.
