National Roaming
نویسنده
چکیده
National roaming is a form of infrastructure sharing in mobile communication networks, where an operator opens his network for a competitor’s customers and is compensated by a usage based charge. Arguments in favour of national roaming include the reduction of network investments or faster network rollout. This paper examines the effects of national roaming on competition, network investments and welfare. Using an oligopoly setup with ex-ante capacity investments and incomplete contracts, it is shown that cooperation might increase production efficiency but does not affect total network capacity.

متن کاملRoaming is the dominant mechanism for molecular products in acetaldehyde photodissociation.
Reaction pathways that bypass the conventional saddle-point transition state (TS) are of considerable interest and importance. An example of such a pathway, termed "roaming," has been described in the photodissociation of H(2)CO. In a combined experimental and theoretical study, we show that roaming pathways are important in the 308-nm photodissociation of CH(3)CHO to CH(4) + CO. The CH(4) prod...
