In diesem Beitrag wird ein Oligopolmodell der Innovationsaktivität entwickelt und mit Daten aus dem Mannheimer Innovationspanel geschätzt. Das Modell erlaubt es, bei der empirischen Umsetzung auf die Verwendung von Marktanteilsdaten und Nachfrageelastizitäten zu verzichten, die typischerweise...

The missing effect of investments of firms in information and communication technologies on productivity is studied by various recent papers (e.g. Oliner and Sichels 1994, Landauer 1995, Brynjolfsson and Hitt 1996). Several explanations are given for this missing link. Our paper deals with two...

Through a survey, economic value estimates were obtained on 962 inventions made in the United States and Germany and on which German patent renewal fees were paid to full-term expiration in 1995. A search of subsequent U.S. and German patents yielded a count of citations to those patents....

Die Ergebnisse der multivariaten Analysen zur Beschäftigungsdynamik und dem Wachstumspotential junger innovativer Unternehmen lassen erkennen, daß junge innovative Unternehmen signifikant höhere Wachstumsraten erzielen als junge Unternehmen mit traditionellen Produkten. Die Abschätzung der...

This paper deals with the effects of publicly funded research at universities, polytechnics and federal research labs on industrial innovations in Germany. We discuss the characteristics of companies that benefit from the findings of public research institutions. In questioning 2,300 companies...

I study the causal effect of the European Union Emissions Trading System (EU ETS) on the productivity of German manufacturing firms. Using administrative firm-level data, I estimate robust production functions for narrowly defined industries. This approach allows for an endogenous dynamic...

Germany and Canada stand at polar ends of the scientific debate over language integration and ascension to citizenship. German naturalization, as of January 2000, contains an explicit language criterion for naturalization. The first German immigration act that will presumably come into effect on...

Recent years have brought growing evidence for an increasing labour demand for high skilled and a deterioration of the labour position of less skilled employees. The two most common explanations for this finding are an increasing international trade and a skill biased technological change....

Conventional theory predicts that productivity gains lead to pay hikes. Pay increases, however, can influence labor productivity. But what about in a corporatist economy? Focusing on Germany, we use an innovative technique developed by Geweke to disentangle the relationship between pay and...

This paper analyses the relevance of information and communication technologies (ICT) for firms' probability of global sourcing of inputs. Using firm-level data from Germany in 2009, which include mainly small and medium-sized firms, the empirical analysis differentiates between manufacturing...
