We test the effect of entry on the tariff choices of incumbent cellular firms. We relate the change in the breadth of calling plans between 1996, when incumbents enjoyed a duopoly market, and 1998, when incumbents faced increased competition from personal communications services (PCS) firms....

We present a Cournot model that compares the critical threshold of collusion in Duopoly and Oligopoly Markets where the actors are private, mixed or public. We assume that the incentive critical threshold for collusion depends on the interconnection fees. The different threshold values...

Mobile telephony is described as a two-sided market where customers are seen as senders and receivers of communications that are mutually beneficial both to callers and receivers. This has implications in terms of market definition and market power. The economics of mobile call termination is...

Competition is emerging in OECD Member State mobile telephony markets, albeit somewhat unevenly and at a slower rate. The study addresses the relationship between market structure and performance, and examines the impact of regulatory policy on competition in these markets. A structural model is...

This study evaluates the impact of competition on quality, innovation and price in Europe’s mobile communications market during the 4G era (2011-18). Our results indicate that European mobile users in more concentrated markets benefitted the most from higher network quality, particularly with...

We test the effect of entry on the tariff choices of incumbent cellular firms. We relate the change in the breadth of calling plans between 1996, when incumbents enjoyed a duopoly market, and 1998, when incumbents faced increased competition from personal communications services (PCS) firms....

In this paper, we address the issue of the appropriate market structure in European mobile markets by presenting empirical evidence on the effect of the number of MNO on investment. Using a structural entry model based on a country-level dataset of 28 European countries, we find that, in average...

We develop models of bilateral oligopoly with two-way traffic exchanges to study the impact of competition and government regulatory policies on the international telephone markets. When carriers in each country are required to act collectively in setting a uniform settlement rate for inbound...
