Mobile number portability


Buehler, S; Haucap, J (2004). Mobile number portability. Journal of Industry, Competition and Trade, 4(3):223-238.

Abstract

This paper examines the consequences of introducing mobile number portability (MNP). We show that if the sole effect of introducing MNP is the abolishment of switching costs, MNP unambiguously benefits mobile customers. However, if MNP also causes consumer ignorance, as telephone numbers no longer identify networks, mobile operators will increase termination charges, with ambiguous net effect on the surplus of mobile customers. We examine how extensions such as MNP based on call-forwarding, termination fee regulation, and alternative means of carrier identification affect these findings and discuss policy implications.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
