One-phone service and mobile market foreclosure

Sang Taek Kim, Dong-Ju Kim

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 1 > 59-68

This paper constructs a simple, mixed bundling model of one-phone service to explore its social effects. The study demonstrates that the fixed line monopolist has an incentive to foreclose the competitive mobile market through the provision of one-phone service. In other words, efficient mobile firms will be driven out of the market. This finding, however, contrasts with the existing findings of the...

Ensuring trust in one time exchanges: solving the QoS problem

Bernardo A. Huberman, Fang Wu, Li Zhang

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 1 > 27-37

We describe a pricing structure for the provision of IT services that ensures trust without requiring repeated interactions between service providers and users. It does so by offering a pricing structure that elicits truthful reporting of QoS by providers while making them profitable. This mechanism also induces truth-telling on the part of users reserving the service.

An IT professional’s dilemma: be an entrepreneur or a consultant?

Rajeev K. Goel, Iftekhar Hasan

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 1 > 17-25

Using a simple model, this paper examines the behavior of an IT professional who faces the choice between becoming an entrepreneur or an employee. To our knowledge, this is the first formal study of the dilemma facing an IT professional. IT professionals are somewhat unique in that they embody enough labor input/intellectual property that even a single professional can deliver a viable product/service...

Can the HM-test be brought to an end?

Wolfgang Briglauer, Anton Schwarz

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 1 > 1-16

A significant change seen in the new regulatory framework for communications markets regards issues of market delineation. Relevant markets according to the new regulatory framework should be defined in accordance with competition law methodology/principles, most notably the so-called Hypothetical Monopolist Test (HM-test). Our discussion points to the conceptual and practical difficulties associated...

Signalling cost with investment in compatibility

Mikko Mustonen

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 1 > 39-57

When buyers value products in terms of the expected compatibility between the current and the new vintage, firms can invest strategically in R&D to control for the switching costs. Open announcements of R&D budgets transmit information. The announcements determine the buyers' beliefs of the compatibility. As only an efficient firm finds it optimal to have a large R&D-budget, a firm can...

Private peering, transit and traffic diversion

Narine Badasyan, Subhadip Chakrabarti

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 2 > 115-124

Private peering refers to settlement-free connectivity agreements between Internet Service Providers meant to interconnect their networks by-passing congested National Access Points. We explore the incentives for bilateral peering with particular emphasis on traffic diversion. A private peering agreement between two providers improves the quality of both and would divert traffic from third parties...

A network modeling approach for the optimization of Internet-based advertising strategies and pricing with a quantitative explanation of two paradoxes

Lan Zhao, Anna Nagurney

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 2 > 97-114

This paper addresses the determination and evaluation of optimal Internet marketing strategies when a firm is advertising on multiple websites. An optimization model is constructed for the determination of the optimal amount of click-throughs subject to a budget constraint. The underlying network structure of the problem is then revealed and exploited to obtain both qualitative properties of the solution...

Scalability and robustness of a network resource allocation system using market-based agents

Nadim Haque, Nicholas R. Jennings, Luc Moreau

NETNOMICS: Economic Research and Electronic Networking > 2005 > 7 > 2 > 69-96

In this paper, we consider issues associated with scalability and robustness in designing a market-based multi-agent system that allocates bandwidth in a communications network. Specifically, an empirical evaluation is carried out to assess the system performance under a variety of design configurations in order to provide an insight into network deployment issues. This extends our previous work in...
