Cloud-Computing umschreibt einen fundamentalen Wandel im Bereich der Informations- und Kommunikationstechnologien (IKT). Zunehmend werden Softwareanwendungen, aber auch Hardwarefunktionen wie Speicherplatz und Rechenkapazität nicht mehr zur dauerhaften Nutzung an einem lokalen Computer...

In this paper, we study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve. We address two specific questions: First, does information about usage intensity over time allow us to draw conclusions about the underlying drivers of technology diffusion?...

This paper analyzes the effect of inter urban buses competing on a few routes against trains within an established railway network. In line with expectations, we show that this can lead to unprofitable train service on these routes. However, within an established railway network with every track...

This paper surveys a variety of topics related to network economics. Topics covered include: consumer demand under network effects, compatibility decisions and standardization, technology advances in network industries, two-sided markets, information networks and intellectual property, and...

Can stock market bubbles accelerate long term growth? Do such bubbles indicate irrational behavior? This paper studies the effect of innovation uncertainty on the concomitant time path of firm valuations, technology adoption and growth in a setting that incorporates positive network...

In this paper we investigate whether markets with heterogeneous network externalities can belocked-in by old technologies even if superior technologies are available. Heterogeneous networkexternalities are present when some consumers care more about the size of the market share of agood than...

We investigate the implications of Network Neutrality regulation for Internet fragmentation. We model a two-sided market, where Content Providers (CPs) and consumers interact through Internet Service Providers (ISPs) and CPs sell consumers' attention to advertisers. Under Network Neutrality, CPs...

We enquiry about the effects of first and second order stochastic dominance shifts of the distribution of the consumers’ willingness to pay, within the standard model of a market with network externalities and hump-shaped demand curve. This issue is analyzed in the polar cases of perfect...

We investigate the relation between Net Neutrality regulation and Internet fragmentation. We model a two-sided market, where Content Providers (CPs) and consumers interact through Internet Service Providers (ISPs), and CPs sell consumers' attention to advertisers. Under Net Neutrality, a...
