We consider an application of the Stackelberg leader-follower model in prices in a simple two-firm network as a possible way to help resolve externalities that can be harmful to firm profit and welfare. Whilst independent pricing on the network yields lower profit and sometimes even lower...

A simple theoretical network model is introduced to investigate the problem of network interconnection. Prices, profits and welfare are compared under welfare maximisation, network monopoly and network monopoly with competition over one part of the network. Given that inducing actual competition...

In this paper we explore alternative pricing and regulatory strategies within a simple transport network with Cournot duopoly and differentiated demands. We show that whilst firms always prefer to offer integrated ticketing, a social planner will not. With integrated ticketing, the firms always...

The general complexity of demand interrelationships including the co-existence of complements and substitutes make traditional methods of regulating network industries problematic. Collusive pricing is preferred to independent pricing on complementary sections of a network whilst the reverse is...

We introduce a new regulatory concept: the independent profit-maximising agent, as a model for regulating a network monopoly. The agent sets prices on cross-network goods taking either a complete, or arbitrarily small, share of the associated profit. We examine welfare and profits with and...
