Taking into consideration the new dimensions of port production that have become evident during the resent past, this paper tackles the issue of port reorganisation. In the light of the changes in the world economy and the new competitive environment, the paper focuses on the new structures of...

International Transport Services (ITS) play an important role in influencing international trade flows. This paper develops an analytical framework in which ITS costs are endogenously determined. It shows that ITS sector liberalization foster international trade very much the same way tariff...

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...

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...

We provide a new explanation for the apparent underpricing of initial public offerings applicable to large, regulated firms like telecommunications companies. Under the assumption that regulation is subject to political pressure by voters we demonstrate that it may be rational for issuers to...

Voter turnout is frequently cited as gauging a polity's health. The ease with which electoral members produce political support can, however, retard an economy's productive capacity. For example, while mobile electorates might efficaciously monitor political agents, they may also lack...

The market for information and communication technologies is changing rapidly. Products and applications that used to be completely separate are becoming almost interchangeable. Sweeping change lies ahead in voice and data telephony: the fixed-line telephone network faces new competition from...

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...

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...
