We use a unique rich newly built data set for German manufacturing enterprises to investigate the product differentiation 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...

We use a unique rich newly built data set for German manufacturing enterprises to investigate the relationship between product diversification and the stability of sales and employment. We find that contrary to portfolio theoretic considerations more diversified firms exhibit a higher...

This paper uses a large plant level panel data set from Germany and a matching approach to look for causal effects of starting to export on plant performance. We find positive effects on growth of employment, labor productivity, and wages.

This empirical paper documents the relationship between the composition of a firm's workforce (with a special focus on age and gender) and its performance (productivity and profitability) for a large representative sample of enterprises from manufacturing industries in Germany using newly...

Presence on the web tends to be important for firms. Empirical studies show that firms with a better performance along various dimensions, and firms that are more internationally active, tend to have a website. Furthermore, a website helped firms to survive in times of the COVID-19 pandemic. An...

A presence on the web tends to be important for firms. Empirical studies show that firms with a better performance across various dimensions, and firms that are more internationally active, tend to have a website. Furthermore, a website helped firms to survive during the COVID-19 pandemic. An...

This paper uses a newly available comprehensive panel data set for manufacturing enterprises from 2001 to 2005 to document the first empirical results on the relationship between imports and productivity for Germany, a leading actor on the world market for goods. Furthermore, for the first time...

This study reports results from an empirical investigation of business services sector firms that (start to) export, comparing exporters to firms that serve the national market only. We estimate identically specified empirical models using comparable enterprise level data from France, Germany,...

While it is a stylized fact that exporting firms pay higher wages than non-exporting firms, the direction of the link between exporting and wages is less clear. Using a rich set of German linked employer-employee panel data we follow over time plants that start to export. We show that the...
