This empirical research note documents the relationship between composition of a firm's workforce (with a special focus on age and gender) and its performance with respect to innovative activities (outlays and employment in research and development (R&D)) for a large representative sample of...

This paper contributes to the literature by providing the first evidence on the link between innovation activities (measured by the share of engineers and scientists in the workforce) and exports of German business services firms based on a large representative longitudinal sample of...

This study uses newly available representative data from German business services firms and a continuous treatment approach based on the generalized propensity score to test for a causal effect of R&D activities (measured by the share of engineers and natural scientists in all employees) on the...

Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of cannibalizing sales of existing varieties. While more productive firms always have a higher market share, there is no...

Using a knowledge production framework and a rich set of plant level data this study demonstrates that in Germany firms that are active on international markets as exporters or foreign direct investors do generate more new knowledge than firms which sell on the national market only. These...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...
