Matching process generated business data and survey data : the case of KombiFiD in Germany

"In Germany, process-generated data and survey data on firms are collected by different data producers. Each data producer provides access for researchers to its data, but the combination of datasets from different producers is not possible at the moment. A new project (KombiFiD) aims to overcome this limitation: firm data collected by the German Statistical Offices, the Deutsche Bundesbank and the Federal Employment Agency will be linked for the first time. The project aims are twofold: to gauge the possibilities of linking selected datasets beyond the limits of individual labour market data producers and to provide a combined dataset to science, thereby creating new research opportunities. In the following we describe the project, the selected data-sets and explain potential matching problems. In this context we address e.g. the advantages and disadvantages of survey and process generated data and some challenges we expect within the project."

Using worker flows in the analysis of establishment turnover : evidence from German administrative data

"Economists have long been interested in the determinants and components of job creation and destruction. In many countries administrative datasets provide an excellent source for detailed analysis on a fine and disaggregate level. However, administrative datasets are not without problems: restructuring and relabeling of firms is often poorly measured and can potentially create large biases. We provide evidence of the extent of this bias and provide a new solution to deal with it using the German Establishment History Panel (BHP). While previous research has relied on the first and last appearance of the establishment identifier (EID) to identify openings and closings, we improve on this approach using a new dataset containing all worker flows between establishments in Germany. This allows us to credibly identify establishment births and deaths from 1975 to 2004. We show that the misclassification bias of using only the EID is very severe: Only about 35 to 40 percent of new and disappearing EIDs with more than 3 employees correspond unambiguously to real establishment entries and exits. Among larger establishments misclassification is even more common. We show that many new establishment IDs appear to be 'Spin-Offs' and these have become increasingly more common over time. We then demonstrate that using only EID entries and exits may dramatically overstate, by as much as 100 percent, the role of establishment turnover for job creation and destruction. Furthermore correcting job creation and destruction measures for spurious EID entries and exits reduces these measures and aligns them closer with the business cycle."

The Establishment History Panel (BHP) 1975-2008 : Handbook Version 1.0.2

"The Establishment History Panel 1975-2008 V1 is a 50% sample of all establishments throughout Germany which have at least one employee liable to social security as of 30th June of a given year or, since 1999, also establishments which have at least one marginal part-time employee. This data report describes the variables of the weakly anonymous version of the 1975-2008 V1 BHP dataset, which is available to researchers via on-site use at the Research Data Centre (FDZ) or via remote data access. The BHP data are predominantly original data, with the sole exception that the original establishment numbers, which are direct identifiers for the different establishments, have been replaced by artificial establishment numbers. In order to protect the anonymity of the establishments still further, some variables are classified as particularly sensitive and are only disclosed on submission of a special application (see Chapter 1.2). The Datenreport on the BHP 1975-2008 V1 is structured as follows. In addition to the introduction, Chapter 1 contains an outline of the data as well as information regarding the so-called volume structure and about data access. Chapter 1 also contains a brief overview of the differences between this version and its predecessor BHP 1975-2006 V2.0.1 in order to make it possible for users of the older version to switch to the new one quickly. A description of the data source can be found in Chapter 2. The data preparation and data quality are discussed in Chapters 3 and 4. Chapter 5 contains detailed descriptions of the variables."

Combined Firm Data for Germany (KombiFiD): matching process-generated data and survey data

'In Deutschland werden prozessproduzierte bzw. Befragungsdaten von verschiedenen Institutionen erhoben. Zwar ist der Zugang zu diesen Daten für Wissenschaftler generell möglich, eine Verknüpfung von Datensätzen verschiedener Datenproduzenten ist derzeit jedoch nicht realisierbar. Ein neues Projekt (KombiFiD) verknüpft daher Unternehmensdaten des Statistischen Bundesamtes, der Deutschen Bundesbank und der Bundesagentur für Arbeit. Die Projektziele sind dabei zum einen, die Möglichkeiten der Verknüpfbarkeit von Datensätzen verschiedener Datenproduzenten zu prüfen, und zum anderen, der Wissenschaft einen kombinierten Datensatz anzubieten, mit dem neue Forschungsfragen behandelt werden können. Im Folgenden werden das Projekt, die ausgewählten Datensätze sowie mögliche Matchingprobleme beschrieben. In diesem Zusammenhang werden u.a. auch Vor- und Nachteile von Umfrage- bzw. prozessgenerierten Datensätzen benannt.'

Kombinierte Firmendaten für Deutschland - (KombiFiD) : Handbuch Version 1.0

"This Datenreport provides an overview of the dataset (Version 1.0), which was developed in the project KombiFiD (Kombinierte Firmendaten für Deutschland). Within the project KombiFiD, data from the Statistical Offices, the Federal Employment Agency and the Deutsche Bundesbank was linked for a sample of firms. The aim of this linkage was to generate a dataset with a considerably higher analytical potential than the individual datasets. The dataset is created as a panel covering the years 2003-2006 with an average number of cases of about 14.000 firms per year. The Datenreport is structured as follows. After a short introduction in chapter 1, chapter 2 outlines the sampling procedure, the response rate as well as the results of the linkage procedure. In Chapter 3 the data access and the application procedure are shown. Chapter 4 gives an overview of the linked individual data bases, whilst Chapter 5 lists all variables of the combined KombiFiD dataset. More detailed variable descriptions can be found in the appendices."
