The aim of this paper is to estimate the importance of (induced) network effects in the use of mobile telephones and the impact of the structure of social networks on a consumer's adoption decision. This is done using social network data obtained from a survey of second year undergraduate...

I generalize the workhorse model of network competition to include income effects in call demand. Empirical work has shown call demand to increase signi ficantly with income. For any positive income effect, network operators prefer a termination rate above marginal cost if networks are...

We consider internet service providers' incentives to zero-rate, i.e. do not count towards data allowances, the consumption of certain services, in the absence of payments from content providers. In a general model with various types of network effects, service substitutes or complements,...

In this paper, we take a critical perspective on the common regulatory reply to deal with call termination on mobile networks. The current policy tendency to deal with fixed-to-mobile call termination is to restrict attention to the defined relevant market (call termination on single networks is...

Using quarterly data of 58 countries, this paper provides empirical evidence that mobile phone diffusion from 2007 to 2009 is positively influenced by international network effects. Direct and indirect network effects are a result of the international standadization of telecommunication...

Termination charges toward newer entrants are often set asymmetrically to exceed efficient costs for telephony traffic. Such practices are said to be beneficial to consumers as well as providing competition a quot;leg-upquot;. However claims of consumer benefit are dubious at best, while infant...
