PhD position in Tele-economics

A PhD position within the area of tele-economics is available at the Department of Telematics, NTNU.

Background

During the last decades, the telecommunication market has moved from a vertical monopoly market to a horizontal competitive market in most countries. Before the privatization of the telecommunication industry, a small set of networked services (PSTN, fax, satellite telephony…) were provided by a single network operator / service provider (the incumbent). In Norway, Televerket/Telenor had this role. Today, instead of a single monopolist, there are numerous actors competing in a horizontal market, resulting in a huge number of services that can be provided over a number of communication networks. These actors comprise owners of network infrastructure and independent service providers offering their services over these networks.

This evolution has resulted in a more complex market structure, with a number of different players providing value to telecommunication services by using a variety of business models, many of which are based on positive network externalities, extreme (exponential) growth, and aiming at market monopoly, i.e. features uncommon for traditional studies within market economics. In large parts, these characteristics are the results of the technological properties of the dominant ICT.

Hence, new communication technology creates new opportunities that to some extent influences how business is done within the telecommunication market. Therefore, it is important to study the market from a technological perspective. That is, how does the technology itself influence the dynamics of the marketplace, the versatility and lifetime of products, pricing of services and networks, impact of network economics and social groups, and valuation of assets? In particular, to gain a better understand of this market, models on economic network theory should be studied and seen in relation with communication networks and networked services [1] [2] [3] [4].

Topics to be studied

The outlined PhD position proposal focuses on matematical modelling of telecommunications market behaviour, examples include:

  • Mathematical models for markets with and without feedback.
  • Advanced models for telecommunications markets, including the dynamics of oligopolies, development of monopolies in oligopolisitc markets, evolution of trends, effects of lock-in, impact of regulation, churning (time-based and stochastic), …
  • Simulations of telecommunications markets using discrete-event simulations and market agents.

Application

We seek a highly motivated individual holding a Master’s degree in Telematics, Computer Science or other relevant disciplines, preferably with strong background in economics. Candidates with experience in mathematical modelling and simulations will be favoured. You can find application details at http://www.item.ntnu.no/department/positions
