Using data from the social survey ALLBUS for West Germany in the period 1980 to 2006, this paper demonstrates that union members are on average older than non-unionized employees. The probability of being unionized shows the inverted U-shaped pattern in age conjectured by Blanchflower (BJIR...

Using OLS and quantile regression methods and rich cross-section data sets for western and eastern Germany, this paper demonstrates that the impact of works council presence on labor productivity varies between manufacturing and services, between plants that are or are not covered by collective...

An analysis of European employment deficits using employment-population ratios shows that there exist unexhausted employment potentials in many EU countries, in particular for older employees, but also for women and in the service sector. If the EU-15 were to match the U.S. employment-population...

Using representative linked employer-employee data of the German Federal Employment Agency, this paper analyzes to which extent full-time employees who earned low wages (less than two-thirds of the median wage) in 1998/99 were able to earn higher wages in the following years, and which factors...

Eine Auswertung repräsentativer Daten des IAB-Betriebspanels zeigt, dass im Jahr 2000 knapp die Hälfte der westdeutschen, aber nur gut ein Viertel der ostdeutschen Betriebe durch Flächen- oder Firmentarifverträge gebunden waren, wobei die Flächentarifbindung in den letzten Jahren...

This paper contributes to the literature by documenting for the first time the contribution of adding (and dropping) goods and destination countries to the sharp increase in exports of goods in the German economy as a whole during the Great Export Recovery in 2009/2010. The empirical...

This is the first study of the link between internationalization and firm survival during the 2008/2009 crisis in Germany, a country which was hit relatively lightly compared to other countries. Moreover, it is the first study which looks at the role of importing, exporting and FDI...

We use unique rich data for German manufacturing enterprises to investigate the product diversification – firm performance relationship.We find that an increase in the degree of product diversification has a negative impact on profitability when observed and unobserved firm characteristics are...

In empirical studies often the values of some variables for some observations are much larger or smaller than the values for the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses. Conclusions based on a...

This paper contributes to the literature on the use of anonymized firm level data by reporting results from a replication study. To test for the practical usefulness of anonymized data I selected two of my published papers based on different cross sections of firm data. The data used there were...
