Recent theoretical models of network competition with call externalities demonstrate strategic incentives of incumbent providers to reduce receiver benefits in rival network by excessive off-net pricing. Such anti-competitive pricing practices have a potentially damaging impact on financial...

We study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve. Specifically, we address two questions: First, can we draw conclusions about the underlying drivers of technology diffusion by studying usage intensity? Second, what is the effect of high...

In this paper we utilize discrete choice experiment method to identify and measure switching costs and network effects in mobile telephony in Poland. Based on hypothetical choices consumers make we construct a conditional random parameters multinomial logit model to analyze their preferences. In...

I develop a structural demand model for mobile telephone service, which facilitates the identification of network effects and compatibility between networks. Network effects are measured by the dependence of consumer willingness to pay on the installed base of subscribers. Compatibility is...

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...

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...

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...
