This study tests for financial constraints on R&D investment and how they differ from capital investment. To identify constraints in the access to external capital, we employ a credit rating index. Our models show that internal constraints, measured by mark-ups, are more decisive for R&D than...

This paper investigates how competition and firm size affect the relationship between market uncertainty and R&D investment. We use an intuitively appealing measure of firm-specific uncertainty along with panel data to show that firms invest less in current R&D as uncertainty about market...

This paper studies the determinants of naturalization among Turkish and ex-Yugoslav immigrants in Germany differentiating between actual and planned citizenship. Using the German Socio-Economic Panel, we measure the impact that integration and ethnicity indicators exert on the probability to...

This paper investigates the impact of in-house R&D and innovation management practices on innovation success in small and medium-sized firms (SMEs). While there is little doubt about the significance of technology competence for generating successful innovations, inhouse R&D activities may be a...

We estimate the effects of R&D on firms' credit ratings and on financial distress. The main purpose is the comparison of firms in Western Germany and Eastern Germany as a transitional economy. Innovative activity has a positive impact on firm value proxied by ratings in Western Germany, but a...

Previous literature provided evidence on financing constraints for investment in R&D activities due to capital market imperfections and special features of R&D investments. Moreover, it has been shown that a shift in capital structure towards more debt, results in a reduction of R&D investments....

The concept of knowledge has gained in interest since industrialized economics have induced a shift in importance from labor, capital and natural resources towards intellectual resources. This study investigates how the management of knowledge influences the innovation performance of a firm....

Upon arrival in the host country, immigrants undergo a fundamental identity crisis. Their ethnic identity being questioned, they can be classified into four states assimilation, integration, separation and marginalization. This is suggested by the ethnosizer, a newly established measure to...

The increasing commercialization of university discoveries has initiated a controversy on the impacts for future scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on more fundamental research efforts in science. Several...

"The paper investigates the role of human capital for migrants' ethnic ties towards their home and host countries. Pre-migration characteristics dominate ethnic self-identification. Human capital acquired in the host country does not affect the attachment to the receiving...
