In 2020, firms expected their innovation expenditures to decrease by about 2% in 2020 compared to 2019. This decline is much smaller than that in 2009 following the financial crisis, when innovation expenditures fell by 11%. However, smaller firms with 5 to 99 employees planned to cut their...

This study presents a novel empirical approach to identify financing constraints for innovation based on the concept of an ideal test (Hall 2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they selected additional innovation projects, they...

Innovation is crucial to economic development. Innovation expenditures in Germany's business sector as well as public funding for science and research have been increasing in the past decade. However, the share of businesses with innovations - especially among the small- and medium-sized ones -...

This paper investigates the interaction between establishment-level codetermination and industry-level collective bargaining in Germany. Based on a simple bargaining model we derive our main hypothesis: In establishments covered by collective bargaining agreements works councils are more likely...

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...

This paper tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of...

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...

This paper analyzes the effects of public R&D subsidies on R&D expenditure in the German manufacturing sector. The focus is on the question whether public R&D funding stimulates or crowds out private investment. Cross sectional data at the firm level is used. By apllying parametric and...

This paper analyses the relationship between firm productivity and export behavior in German manufacturing firms. We examine whether productivity increases the probability of exporting, and assert that there is a causal relationship from high productivity to entering foreign markets, as...

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...
