This is the most probable risk that could be implied by ineffective access pricing regulation. The LRIC methodology has been criticized by several authors. Salinger (1998) and Laffont and Tirole (2001) argued that LRIC regulation provides the regulators with a key tool to manage industry entry. It is, therefore, crucial to ensure that, whenever a mistake is made, it is made in favor of overinvestment rather than underinvestment. Whenever an output is unprofitable, firms can freely dispose corresponding assets by selling them or by dispatching them to other activities.

11 Incremental costs are important in the sense that they reflect the company’s decision for producing A. Usually, in deciding to produce A, the firm expects that revenues generated by A should exceed the incremental cost incurred and provide an earning income to capital above the cost of capital. Nonetheless, incremental costs, as we have just strictly defined, are difficult to use in pricing access to a service or network element, to the extent that they only cover part of the costs. Given that A also uses other network’s resources and is partly responsible for joint costs incurred by the firm, it is necessary to allocate to A a portion of these joint costs.
