Abstract A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected on-net prices. Thus, somewhat paradoxically, deployment of a technology that increases substitutability, and thereby competition, may end up raising prices.

Quality Measurements

This paper summarizes my papers and books, which reports on studies concerning the performance measurement of telephone networks and services, particularly on mobile networks. In detail, the telephone network and service quality measurements are grouped into two, the first is a measurement that aims to measure the provider's customer satisfaction, performed by the provider for internal purposes, or to report to the regulator, and the second measurement goal is that the provider and/or by the vendor in relation to the quality assurance provided by the vendor to the provider. In detail, the first type of measurement uses a sampling technique to refer to the subjective method, otherwise, the second type performs aggregate measurements to refer to the Signaling Ladder Diagram of the telephone services.

Rural Australia

Considerable debate surrounds the provision of mobile telephony to remote and rural Australians. Disquiet about the closure of the analogue network, controversy over its replacement and recognition of potential rural competitiveness from digital technologies are all significant aspects of this debate. Within the discussion surrounding regional and rural development, there is a growing concern over the standard of mobile telecommunications infrastructure in non-metropolitan Australia. Of particular interest are the mechanisms by which infrastructure is provided. More specifically, there appears to be a need for public subsidies for mobile networks since demand may be insufficient to stimulate provision through normal market processes. This paper explores these arguments by drawing on data from the Upper Murray region of New South Wales and Victoria. Empirical results indicate a significant current expenditure by present mobile telephony users and a preparedness to increase this expenditure under an improved service scenario. There is also evidence of relative price inelasticity. This evidence is used to question the conventional wisdom of providing public funds to telecommunications firms to encourage extension of the mobile network to all rural communities.
