A new approach in German innovation policy organizes contests of proposals for developing innovation networks. Based on an overview of the different programs, we investigate the advantages and problems of such an approach. We find that this type of policy may have a relatively large impact and can, therefore, be regarded as a rather efficient instrument of innovation policy. Compared to conventional ...
This paper argues that - in contrast to an often expressed view - the formation of larger and more powerful buyers need not reduce welfare by stifling suppliers' incentives. If contracts are determined in bilateral negotiations, the presence of larger buyers may both increase suppliers' incentives for product improvement and induce suppliers to choose a more efficient technology. The paper also isolates ...

The other group of agents - called capitalists - own and bequeath physical capital. ...

Recent empirical analyses of the relationship between financial system development and economic growth find that financial system development causes economic growth, is a good predictor of growth and that its impact is relatively large. Moreover, the empirical literature predicts that the adverse effects of banking crises on economic growth will rise in the absence of an adequate response by the government. ...
Dieser Artikel führt verschiedene ökonomische Sichtweisen auf Gründe für (zunehmende) Medienkonzentration und ihre Folgen zusammen. Da Medienmärkte durch die Existenz zweiseitiger Netzwerkeffekte geprägt sind, können Fusionen von Medienunternehmen zu unerwarteten Ergebnissen führen, die sich mithilfe der üblichen Konzepte der Industrieökonomik nicht erklären lassen. Im Mittelpunkt der Analyse stehen ...
Ziel der vorliegenden Untersuchung ist es, den Einfluss von Marktstruktur und anderen regionalen Einflussgrößen auf die Preise der Zeitungen für Abonnements und Anzeigen zu analysieren. Im Ergebnis zeigt sich insbesondere eine negative Korrelation von Konzentration und Zeitungspreisen. Die Preise für Anzeigen hängen - anders als die für Abonnements - signifikant vom Einkommensniveau und der Bevölkerungsdichte ...
