We estimate wage and job tenure functions that include individual and firm effects capturing time-invariant unobserved worker and firm heterogeneity using German linked employer-employee data (LIAB data set). We find that both types of heterogeneity are correlated to the observed characteristics...

The aim of this paper is to test how geographical and technological proximity relate to a particular industry's innovative output. Two mechanisms are therefore tested, i.e. agglomeration economies and the regional exploitation of technological proximity. A new dataset is applied, which includes...

There is ample evidence that user-producer interaction is an important factor for successful innovations. It is often claimed that user-producer interaction is most effcient in close proximity. On the other hand, innovations are a major determinant for the export performance of firms. Does this...

Successful innovative activity is a major contribution to the intangible capital of firms. Although its importance is generally acknowledged, the contribution to companies? profits is a priori unclear. We present the results of an empirical study on the effects of the patent stock on...

The present paper first discusses theoretically the different incentives of manager- versus owner-controlled firms for investment into innovative activity. In addition, the role of debt financing is analyzed. Subsequently the results from an empirical study on the determinants of innovative...
