Das neue TKG hat ein besonderes Augenmerk und regulatorische Aufmerksamkeit auf die nach der Liberalisierung der Märkte noch auftretenden Wettbewerbsprobleme gelegt. Eines dieser Probleme ist in § 28 Abs. 2 Nr. 2 adressiert: Die Preis-Kosten-Schere (PKS). Danach muss die Spanne zwischen...

The paper uses a unique dataset comprising the population of new ventures that enter the UK market in 1998. We argue that we would expect the effect of market concentration on firm survival to be different according to whether an industry is static (low entry and exit) or dynamic. In our...

Patente haben Konjunktur. Sie sind kein trockenesThema mehr, das allenfalls ein paar technische Spezialisteninteressiert. Wirtschaftspolitiker werden nichtmüde, Patentstatistiken zu zitieren und intellektuellesEigentum als Baustein der Wissenschaftsgesellschaftzu rühmen. In Beiträgen zur...

In this paper, we present a model of endogenous vertical integration and horizontal differentiation. Thereexists two output brands and two versions of the input. The only mean for output differentiation is the inputversion used in output production. Firms may choose to vertically integrate to...

In this paper, we propose an example of successive oligopolies where the downstream firmsshare the same decreasing returns technology of the Cobb-Douglas type. We stress thedifferences between the conclusions obtained under this assumption and those resultingfrom the traditional example...

In this paper we analyze how the technology used by downstream firms can influence inputand output market prices. We show via an example that both these prices increase under adecreasing returns technology while the contrary holds when the technology is constant....

We consider how the amount of the technology transferred and the characteristics of the partneraffect licensing. We find that a partial technology transfer can be the joint-profit minimizingtransfer, though under weakly concave demand, a complete transfer always increases joint profitif there...

Research and Development (R&D) and innovation are crucial features of the seed industry. To supportlarge R&D investments by the private sector, strong intellectual property rights, such as patents, arenecessary. The exclusivity granted by patents naturally creates market power positions and...

Basic innovations are often fundamental to the development of applications that maybe developed by other innovators. In this setting, we investigate whether patent pools canrectify the lack of incentives for developers to invest in applications. Following Green andScotchmer (1995), we also...
