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 study the impact of co-investment by incumbents and entrants on the roll-out of network infrastructures under demand uncertainty. We show that if entrants can wait to co-invest until demand is realized, the incumbents' investment incentives are reduced and total coverage can be...

Competition authorities must pay attention to many industries simultaneously. Sectoral regulators concentrate on their own industry. Often both types of authority may intervene in specific industries and there is an overlap of jurisdictions. We show how a competition authority's resource...

Often, fi xed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile...

Investments in Next Generation Access Networks (NGANs) ask for a new set of regulatory remedies. This paper contributes to this debate by focusing on three issues: the migration from the legacy copper network to the NGA infrastructure, and how wholesale pricing regulation might affect this...

We introduce a flexible model of telecommunications network competition with non-uniform calling patterns, which account for the fact that customers tend to make most calls to a small set of contacts. Equilibrium call prices are distorted away from marginal cost, and competitive intensity is...

In this paper, we analyse the specific national broadband plans which have been developed by some European governments to foster the deployment of next generation access networks, namely in France, Italy, and Portugal. In particular, we discuss the strategies adopted to achieve wide fibre...

In this paper, we study the impact of co-investment by incumbents and entrants on the roll-out of network infrastructures under demand uncertainty. We show that if entrants can wait to co-invest until demand is realized, the incumbents' investment incentives are reduced and total coverage can be...

We analyze the impact of mandatory access on the infrastructure iinvestments of two competing communications networks, and show that for low (high) access charges firms wait (preempt each other). Contrary to previous results, under preemption a higher access charge can delay first investment....

We analyse the effects of universal service obligations, such as uniform pricing, price caps and unbundling, on allocations in markets newly opened to competition, e.g. telecommunications. If uniform pricing is imposed not only on incumbents but also on entrants, entry may not result in...
