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,...

The transformation of the European energy system requires substantial investment in transmission capacity to facilitate cross-border trade and to efficiently integrate renewable energy sources. However, network planning in the EU is still mainly a national prerogative. In contrast to other...

In the European Union's (EU) gas transmission system the relative prices of short-term transmission capacities are specified via factors called multipliers. Previous literature indicates that, depending on the region, there exist optimal multiplier levels that can allow transport tariffs to be...

A considerable literature has extolled the virtues of transitioning away from rate-of-return regulation for infrastructure-intensive industries. I find that for a large-scale transmission network like the U.S. natural gas pipeline system, transmission capacity under rate-of-return regulation may...

We model the optimal regulation of continuous, irreversible, capacity expansion, in a model in which the regulated network firm has private information about its capacity costs, investments need to be financed out of the firm's cash flows from selling network access and demand is stochastic. If...
