The distinguishing feature of two-sided markets is that the pricing structure, that is, the relative prices charged to each side, matters. Regulators need to understand and account for the interdependence of prices in both sides. Some interventions that lower the prices on one side can result in...

In order to overcome the problem of free-riding in current P2P system, we suggest applying social network theory. Based on our exploration of the overlapping research fields of social networks and peer-to-peer networks, we propose a new P2P framework within this paper. It specifies social...

This chapter explains the logic of structural econometric models and compares them to other types of econometric models. We provide a framework researchers can use to develop and evaluate structural econometric models. This framework pays particular attention to describing different sources of...

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...

This paper estimates demand elasticities for the Turkish mobile telecommunication market. In contrast to most other studies, firm level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...

This paper estimates the impact of entries and mergers on the price of mobile voice services in a panel database of 27 European Member States between 2003 and 2010. Our difference-in-differences econometric methodology exploits the variance in different structural changes between countries to...

We test for the distributional effects of regulation and entry in the mobile telecommunications sector in a highly unequal country, South Africa. Using six waves of a consumer survey of over 134,000 individuals between 2009-2014, we estimate a discrete-choice model allowing for...

In theory, network profits are independent of the reciprocal termination rates when operators charge nondiscriminatory call prices (Laffont, Rey and Tirole, 1998). Additionally, termination rates can be used to subsidize subscriber acquisition cost. This issue is typically known as a "waterbed...

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 competitors'...

How does the choice to regulate a market take place? And how does regulation influence market outcome? We argue that to explicitly model the simultaneity between these two issues makes a qualitative difference in the analysis of the role of regulation, and empirically test our model in the U.S....
