Abstract In markets with competing interconnected networks like mobile telecommunication markets investments affect the investor’s and also any competitors’ profits. In a theoretical model it is shown that cost-reducing investments reduce the investor’s termination rates and increase...

Im November veröffentlichte die Bundesnetzagentur ihre Entscheidung zu den Vergaberegeln von insgesamt 120 bzw. 300 MHz Funkspektrum in den Bereichen 2 GHz und 3,6 GHz, die im Frühjahr 2019 versteigert werden. Torsten J. Gerpott, Universität Duisburg-Essen, stellt die Auflagen zur...

We explore the existence of first mover advantages in mobile telecommunications markets. Building on a data set comprising monthly penetration rates, market concentration, number of active operators, and market shares of 90 followers from 33 OECD countries, we estimate a dynamic growth model....

Next generation access networks (NGAN) will support a renewed electronic communication market where main opportunities lie in the provision of ubiquitous broadband connectivity, applications and content. From their deployment it is - much - expected a wealth of innovations. Within this framework...

The study assesses the role of mobile phones and mobile banking in decreasing inequality in 52 African countries. The empirical procedure involves first, examining the income-redistributive effect of mobile phone penetration and then investigating the contribution of mobile banking services in...

Using twenty-five policy variables, we investigate determinants of mobile phone/banking in 49 Sub-Saharan African countries with data for the year 2011. The determinants are classified into six policy categories, notably: macroeconomic, business/bank, market-related, knowledge economy, external...

The contribution of this paper to complement theoretical and qualitative mobile penetration literature with empirical evidence is twofold: firstly, we assess the income-redistributive effect of mobile phone penetration and; secondly, the instrumentality of financial development dynamics in this...

The object of this paper is to complement theoretical 'mobile penetration' literature with empirical evidence in a dual manner: on the one hand, assess the income-redistributive effect of mobile phone penetration and; on the other hand, the instrumentality of good governance in this nexus. Main...

Purpose - The aim of this paper is to complement theoretical and qualitative literature with empirical evidence on the income-redistributive effect of mobile phone penetration in 52 African countries. Design/methodology/approach - Robust Ordinary Least Squares and Two Stage Least Squares...
