Este trabajo analiza la entrada y la competencia en servicios de telecomunicaciones, en los que las empresas se diferencian por sus costes hundidos y por la valoración que reciben de los consumidores. En este marco de análisis desaparece el problema de coordinación presente en la literatura...

Inflated retail prices and termination rates for international telecommunications have spawned traffic re-routing practices, including call turnaround (e.g., callback) and re-origination via third countries. The US and other liberalized countries that allow telecom competition favor such...

We compare the social welfare generated by a domestic government in the two types of policy setups: a "commitment" regime in which the government sets its policy instrument before the strategic choice is made by the domestic firm and a "non-commitment" regime where the policy variable is set...

The paper applies the evolutionary concept to an analysis of the role of intellectual property rights protection in the model of two countries North and South (and two firms) where only the Northern firm conducts innovative activity. The concept of social evolution and learning in oligopolistic...

We introduce call externalities in the standard model of network competition with termination-based price discrimination, and employ a simple graphical analysis to study the outcome of competition. In contrast to recent results in the literature, we find that even under linear pricing, access...

I show that under network competition with termination-based price discrimination access charges below marginal cost may be used as a collusion device, if the utility of receiving calls is accounted for. This holds even for linear prices and sharply contrasts recent results in the literature...

One important determinant of the speed and success of transition will be the efficiency of transformation and development of the infrastructure sectors. A great deal of attention has been paid to issues such as privatisation, restructuring, user prices, and terms of access in these sectors,...

We argue that the optimal configuration of contractual and relational governance mechanisms in an alliance is contingent not only on the amount of asset specificity, but on the nature of the asset involved in the alliance. Physical assets are more suited to contractual controls, while knowledge...
