Zusammenfassung Die Messewirtschaft ist in Deutschland durch eine Konkurrenz privater und öffentlicher Messeveranstalter gekennzeichnet. Im Gegensatz zu den privaten Veranstaltern sind die öffentlichen Messeveranstalter vertikal integriert: Sie besitzen und betreiben einerseits die lokale Messeinfrastruktur, veranstalten aber auch selbst zahlreiche...

The authors analyse how the market transparency unit for fuels in Germany affects both supplier and consumer behaviour. The number of price changes has increased, mainly due to increasing price cuts, as has the spread between the lowest and the highest price of the day – both indicators of intensified competition. The concern that the introduction...

Der vorliegende Beitrag ermittelt das aktuelle Ausmaß kommunaler Betätigung in der Abfallwirtschaft auf Basis von 9248 deutschen Gemeinden und Städten. Vor allem in Großstädten mit über 100.000 Einwohnern haben Kommunen fast vollständig die Restmüllsammlung übernommen. Zwar wird insgesamt über alle Kommunen betrachtet nur für knapp 34 % der Gebiete...

The market for passenger transport has significantly changed since the German long-distance bus market has been deregulated in January 2013. Today we already find significant effects on long-distance rail transport services, especially in the periphery of the rail network. We find that the demand for high-speed trains in Germany, called Intercity E...

It has been long known that firms can benefit substantially from basic research. Recently, however, the open innovation literature has questioned whether firms should conduct these basic research activities in-house and has suggested that outsourcing is more appropriate both for small and large firms. However, existing empirical work investigates t...

Research conducted by university researchers for industry constitutes one of the main channels through which knowledge and technology are transferred from science to the private sector. Since the value of such inputs for the innovation performance of firms has been found to be considerable, it is not surprising that firms increasingly seek direct a...

This paper explores the contribution of design activities on product market performance of Belgian companies. While there is mounting evidence that design can be seen as a strategic tool to successfully spur sales of new product developments at the firm level, the topic of design innovation has not been linked to the open innovation concept yet. In...

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. This article complements this literature by compartme...

Many studies investigate the relationship between R&D and patents applying knowledge production functions. Using aggregated R&D may underestimate the productivity of ‘R’, as mainly ‘R’ but not ‘D’ leads to patents. Disaggregating ‘R’ and ‘D’ shows a significant premium of ‘R’ towards patenting.

This paper examines the relationship between trade liberalisation and migration in the case of Mexico. The increasing bilateral trade between Mexico and the United States after signing the North American Free Trade Agreement (NAFTA) was supposed to stem the illegal Mexican migration flow by contributing to economic growth and job creation in both c...

This paper aims at assessing the level of efficiency of public R&D spending and public R&D support for private R&D among OECD countries over the past two decades. The differences observed in efficiency scores across countries are explained in relation to framework conditions, e.g. the degree of competition, the nature of IPR regime, the access to m...

Several studies have already addressed the question whether R&D subsidies lead to additionality effects or crowd out firms’ private investment. This paper provides insights into the impact of R&D grants on private R&D expenditure, distinguishing between research and development activities. We employ parametric treatment effects models and IV regres...
