Filling the Gap - Firm Strategies for Human Capital Loss, Academy of Management Annual Meeting Proceedings, 2020 (1), 2020 (1)71. DOI
(2020).- This paper explores how the premature death of an inventor affects the productivity and career trajectories of co-inventors. To this end, we develop and analyze a dataset covering the careers of 152,350 German inventors. The data combine highly precise employer-employee data from official social security registers with patent office information covering the period from 1980-2014. Departing from 799 registered premature deaths of inventors and the same number of matched inventors, we study how co-inventors were affected by the death of their peers. Using a difference-in-differences and an event study design, we investigate the reaction of the co-inventors' patenting activities, career advancement and job mobility. Using a number of measures and robustness checks, our results show that the premature death of a co-inventor reduces the productivity of the surviving co-inventors. The effect sets in immediately and survivors do not seem to recover from the shock in the five years following. We argue that employers will seek to retain co-inventors under certain conditions in order to continue lines of research and invention. The empirical results confirm our expectations: surviving inventors are significantly less likely to move to a different employer and are more likely to be promoted compared to inventors in the control group. These effects seem to diminish after about two years."

(2018).Social Ties and Patent Quality Signals – Evidence from East German Inventor Migration, Academy of Management Proceedings, 2016 (1). DOI
(2017).- We study the impact of social ties and publicly observable performance signals on the mobility of knowledge workers. In our empirical setting we exploit the fall of the Iron Curtain as a natural experiment for the migration decision of East German inventors. We identify 21,935 East German Inventors via their patenting track records prior to 1990 and social security records in the pan-German labor market. By modeling their mobility decision after 1989, we find that West regions with more pronounced social ties attracted more inventors. However, inventors with better performance indicators prior to 1990 are substantially less dependent on these social ties for their migration decision. We find additional evidence that the same group of inventors manage to enter regional labor markets that fit significantly better to their origin region in East Germany. We conclude that social ties support labor market access while visible labor market signals reduce the dependence on these ties

Is There a Life Cycle in All Industries? First Evidence from Industry Size Dynamics in West Germany, Applied Economics Letters, 24 (5), 289-297. DOI
(2017).- We propose a novel nonlinear regression approach to test whether the size of industries develops over time along the stylized pattern assumed by the industry life cycle theory. We apply our model on data covering the full spectrum of 205 NACE industries including services in West Germany between 1976 and 2009 and four indicators describing industry size (employment, establishments, entries and exits). The results of our large scale analysis show that in most industries indeed size develops along a cyclical path, albeit this development is not universal. Furthermore, we provide first empirical evidence on service industries where we show that the number of establishments and employees frequently develop in line with what is found for most (product) industries
Wages in High-Tech Start-Ups – Do Academic Spin-Offs Pay a Wage Premium?, Research Policy, 46 (1), 1-18. DOI
(2017).- Wegen ihres Ursprungs an Universitäten operieren akademische Spinoffs an der Spitze der technologischen Entwicklung. Sie haben daher auch im Vergleich mit anderen High-Tech Gründungen eine relativ hohe Nachfrage nach Arbeitskräften mit hochentwickeltem Wissen und technischen Fähigkeiten. Folglich müssen Spinoffs potenziell eine Lohnprämie zahlen, um hinreichend ausgebildete Arbeitskräfte auf dem externen Arbeitsmarkt zu attrahieren und diese im Unternehmen zu halten. Theoretische Studien zu Bestimmungsfaktoren von Löhnen liefern jedoch auch Gegenargumente, die für niedrigere Löhne in Spinoffs sprechen können. Die vorliegende Studie untersucht ob akademische Spinoffs tatsächlich eine Lohnprämie bezahlen und welche Bestimmungsfaktoren mögliche Lohnunterschiede erklären. Zu diesem Zweck werden umfangreiche Employer-Employee-Paneldaten erstellt und mittels Mincer Lohnregressionen sowie erweiterten Panel Schätzverfahren nach Hausman-Taylor analysiert. Die Ergebnisse zeigen, dass Beschäftigte in akademischen Spinoffs nicht grundsätzlich eine Lohnprämie erhalten. Eine Ausnahme von diesem generellen Befund stellen akademischen Spinoffs dar, die universitäre Forschungsergebnisse oder Methodenentwicklungen kommerzialisieren. Diese Firmen zahlen ausschließlich Beschäftigten mit akademischem Abschluss (sowie studentischen Mitarbeitern) signifikante höhere Löhne als vergleichbaren Beschäftigten in anderen Spinoffs bzw. High-Tech Gründungen.

Krise und Strukturwandel am Beispiel der Region Schweinfurt: Nach langer Flaute wieder im Aufwind, IAB-Forum, 2011 (2), 52-59.
(2011).- Die Wirtschaftskrise zu Beginn der 1990er Jahre traf den Raum Schweinfurt besonders hart. Er galt als 'Krisenregion Nr. 1 in Westdeutschland'; die Arbeitslosigkeit erreichte Rekordwerte. Dies hat sich deutlich zum Besseren gewendet. Obwohl die Wirtschaftsleistung in der jüngsten Krise 2008/2009 ebenfalls massiv einbrach, stieg die Arbeitslosigkeit kaum. Der Großraum Schweinfurt steht daher exemplarisch für Regionen, die den Strukturwandel von Regionalwirtschaft und Arbeitsmarkt erfolgreich bewältigt haben.

(2014).Generating Useful Test Data for Complex Linked Employer-Employee Datasets, in: Josep Domingo-Ferrer, Ilenia Tinnirello (
- When data access for external researchers is difficult or time consuming it can be beneficial if test datasets that mimic the structure of the original data are disseminated in advance. With these test data researchers can develop their analysis code or can decide whether the data are suitable for their planned research before they go through the lengthly process of getting access at the research data center. The aim of these data is not to provide any meaningful results. Instead it is important to maintain the structure of the data as closely as possible including skip patterns, logical constraints between the variables, and longitudinal relationships so that any code that is developed using these test data will also run on the original data without further modifications. Achieving this goal can be challenging for complex datasets such as linked employer-employee datasets (LEED) where the links between the establishments and the employees also need to be maintained. Using the LEED of the Institute for Employment Research we illustrate how useful test data can be developed for such complex datasets. Our approach mainly relies on traditional statistical disclosure control (SDC) techniques such as data swapping and noise addition for data protection. Since statistical inferences need not be preserved, high swapping rates can be applied to sufficiently protect the data. At the same time it is straightforward to maintain the structure of the data by adding some constraints on the swapping procedure.

Filling the Gap: The Consequences of Collaborator Loss in Corporate R&D, Max Planck Institute for Innovation & Competition Research Paper, No. 22-17.
(2022).- We examine how collaborator loss affects knowledge workers in corporate R&D. We argue that such a loss affects the remaining collaborators not only by reducing their team-specific capital (as argued in the prior literature) but also by increasing their bargaining power over the employer, who is in need of filling the gap left by the lost collaborator to ensure the continuation of R&D projects. This shift in bargaining power may, in turn, lead to benefits, such as additional resources or more attractive working conditions. These benefits can partially compensate for the negative effect of reduced team-specific capital on productivity and influence the career trajectories of the remaining collaborators. We empirically investigate the consequences of collaborator loss by exploiting 845 unexpected deaths of active inventors. We find that inventor death has a moderate negative effect on the productivity of the remaining collaborators. This negative effect disappears when we focus on the remaining collaborators who work for the same employer as the deceased inventor. Moreover, this group is more likely to be promoted and less likely to leave their current employer.

A Novel Technology-Industry Concordance Table Based on Linked Inventor-Establishment Data, Max Planck Institute for Innovation and Competition Research Paper, No. 17-10.
(2017).- Mapping technologies into industries is frequently required in empirical innovation studies, but many concordances only provide coarse mappings. We develop novel concordance tables between industries and technologies making use of linked inventor-employee patent data for Germany. The data comprise 235,933 patents filed between 1999 and 2011 at the European Patent Office. Data on inventors are matched and disambiguated with social security records available at the Institute for Employment Research. Employment data recorded in this database include detailed industry codes describing the industrial activities of the inventors’ establishments. The linked inventor-establishment microdata allow us to identify the precise industry of origin of inventions, combine them with technology classifications from the inventors’ patents and to generate novel concordance tables. We evaluate our approach by comparing the concordance tables with existing work, and we discuss the validity of patent statistics by industries as indicators for innovation.

(2017).- Die Verknüpfung von Industrie- und Technologiedaten wird häufig für empirischen Arbeiten zu Innovation benötigt. Die Verwendbarkeit existierender Konkordanztabellen ist jedoch durch deren Methodik bzw. Kompatibilitätsprobleme der Daten in der Praxis oftmals stark eingeschränkt. Dieser Methodenreport stellt einen neuartigen Ansatz zur Generierung von Konkordanztabellen vor, der auf verknüpften Erfinder-Betriebs-Daten basiert. Diese Daten enthalten Angaben zu 235,933 Patenten, welche von Erfindern in Deutschland zwischen 1999 und 2011 beim Europäischen Patentamt angemeldet wurden. Erfinder in den Patentdaten wurden mit Beschäftigten in Erwerbsbiografiedaten des Instituts für Arbeitsmarkt- und Berufsforschung (IAB) mittels Record Linkage verknüpft und disambiguiert. Aus der Kombination von industrieller Tätigkeit der Betriebe in denen Erfinder zum Zeitpunkt ihrer Patentanmeldungen arbeiten und den Angaben zu Technologien der angemeldeten Patente, lassen sich mittels Aggregation neuartige, auf Mikrodaten basierende Konkordanztabellen erstellen. Wir vergleichen unsere Technologie-Industrie Konkordanztabellen mit existierenden Ansätzen. Weiterhin wird die Verwendung von Patentindikatoren, die mit der vorgestellten Konkordanztabelle geschätzt wurden, als Maß für die Innovationsstärke von Industrien diskutiert.

Social Ties for Labor Market Access - Lessons from the Migration of East German Inventors, CEPR Discussion Paper, No. 11601.
(2016).- We study the impact of social ties on the migration of inventors from East to West Germany, using the fall of the Iron Curtain and German reunification as a natural experiment. We identify East German inventors via their patenting track records prior to 1990 and their social security records in the German labor market after reunification. Modeling inventor migration to West German regions after 1990, we find that Western regions with stronger historically determined social ties across the former East-West border attracted more inventors after the fall of the Iron Curtain than regions without such ties. However, mobility decisions made by inventors with outstanding patenting track records (star inventors) were not impacted by social ties. We conclude that social ties support labor market access for migrant inventors and determine regional choices while dependence on these ties is substantially reduced for star performers.

Social Ties for Labor Market Access – Lessons from the Migration of East German Inventors, IAB Discussion Paper, 41/2016.
(2016).- Diese Studie untersucht den Einfluss von sozialen Beziehungen auf die Arbeitsmarktmigration von in der DDR aktiven Erfindern, die ab 1990 nach Westdeutschland abgewandert sind. Wir verwenden den Fall des Eisernen Vorhangs sowie die anschließende deutsch-deutsche Wiedervereinigung als natürliches Experiment. Unsere Analysepopulation umfasst Erfinder aus den DDR-Patentdaten vor 1990, welche mit Sozialversicherungsdaten im wiedervereinigten Deutschland verknüpft werden konnten. Wir modellieren Migrationsflüsse dieser Erfinder in westdeutsche Regionen und finden, dass regionale Arbeitsmärkte, die stärker ausgeprägte soziale Beziehungen vor der Wende aufwiesen, die bevorzugten Wanderungsziele von Erfindern waren. Zusätzlich zeigen unsere Analysen, dass "Star-Erfinder", die an potenziell wertvolleren DDR-Erfindungen beteiligt waren, in ihren Migrationsentscheidungen nicht von sozialen Beziehungen abhängig waren. Wir schließen daraus, dass soziale Beziehungen Migration positiv unterstützen und auch die Wahl des regionalen Arbeitsmarktes beeinflussen. Allerdings können hierbei personenbezogene Produktivitätsindikatoren die Abhängigkeit und Nutzung von soziale Beziehungen substituieren.

The Cyclical Dynamics of Industries in West Germany - Testing the Industry Life Cycle Hypothesis, Papers on Economics & Evolution, 1505.
(2015).- We test the industry life cycle hypothesis for 205 industries in West Germany between 1976 and 2009. In particular we analyse whether population indicators follow a cyclical path. Using a novel non-linear regression approach to identify life cycles we find that the number of establishments, employees, entries and exits follow in most industries a path that is well represented by at least a part of a cycle. Most industries that show cyclical behaviour run (partially) through their life cycle in the considered time period.

Wages in High-Tech Start-Ups – Do Academic Spin-Offs Pay a Wage Premium?, IAB Discussion Papers, 17/2015.

- Due to their origin from universities, academic spin-offs operate at the forefront of the technological development. Therefore, spin-offs exhibit a skill-biased labour demand, i.e. spin-offs have a high demand for employees with cutting edge knowledge and technical skills that distinguish them even from other high-tech start-up firms. In order to accommodate this demand, spin-offs may have to pay a relative wage pre- mium compared to other high-tech start-ups. However, neither a comprehensive theoretical assessment nor the empirical literature on wages in start-ups unambigu- ously predicts the existence and the direction of wage differentials between spin-offs and non-spin-offs. This paper addresses this research gap and examines empirically whether or not spin-offs pay their employees a wage premium. Using a unique linked employer-employee data set of German high-tech start-ups, we estimate Mincer-type wage regressions applying the Hausman-Taylor panel estimator. Our results show that spin-offs do not pay a wage premium in general. However, a nota- ble exception from this general result is that spin-offs that commercialise new scien- tific results or methods provide higher wages to employees with linkages to the university sector – either as university graduates or as student workers.

Patterns and Determinants of Inventor Mobility - Evidence from the Employment Biographies of Inventors in Germany (unpublished manuscript).
(2014).Neukonzeption der Typisierung im SGB-II-Bereich - Vorgehensweise und Ergebnisse, IAB-Forschungsbericht, 11/2013, Nuremberg.
(2013).- Since 2006, the IAB develops classifications of job centres, which are regulated ac- cording to the Social Code Book (SGB) II. These classifications account for the fact that there are substantial disparities in the economic or social structure of German regions. These disparities affect the work of local job centres and must be observed if performance figures are compared across regions. This is accomplished by group- ing job centres with similar regional conditions into distinct types. The classifications are updated after several years to account for changing conditions. The present revision goes far beyond a simple update. In principle, it pursues two objectives: for the first time, all three target dimensions of the SGB II are explicitly incorporated into the classification process with equal weights. Additionally, the new types put a stronger focus on factors specific for the job centres regulated by the SGB II. This report documents the revision in detail and presents its results.

(2010).- The Research Data Centre of the German Federal Employment Agency provides high quality micro data on the German labour market. With the Sample of Integrated Labour Market Biographies (SIAB), it offers a new data set suited for the analysis of individual working careers. Compared to its predecessor, the IAB Employment Samples (IABS), the SIAB contains both a longer observation period and more information on individual labour market histories. It can be regarded as the most comprehensive administrative micro-level data set on employment histories that is currently available for Germany.
