Geographically differentiated NGA deployment( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

This paper studies the incentives of an unregulated monopolist to undertake the socially optimal investment in NGA networks when it takes into account the fact that the NGA deployment is a two-dimensional investment decision concerning both the quality (or equivalently, technology) and the geographic coverage. It is found that both the privately and the socially optimal investment decisions result in a geographically differentiated NGA deployment implying that different quality NGA networks are deployed in different geographic areas. In particular, NGA networks of higher (lower) quality are deployed in the more (less) densely populated geographic areas. Although such geographically differentiated NGA investment leads the monopolist to provide a nationwide NGA deployment, it is found that the monopolist underinvests compared to the socially optimal levels of both technology and geographic coverage. In addition, since the objectives of the Europe 2020 Strategy concern both the NGA technology and the NGA coverage, this paper shows that the first objective of providing all Europeans with access to much higher internet speeds of above 30 Mbps is feasible when the demand for NGA-based services is significantly elastic, whereas the second objective of providing internet connection speeds of 100 Mbps to 50% or more of European households is not a feasible goal

Competitive Dynamics in the Operating Systems Market Modeling and Policy Implications by Spyridoula Lakka( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Based on concepts of population dynamics and organizational ecology, the study analyzes the evolutionary and competitive dynamics of the highly concentrated desktop/laptop operating systems market and draws conclusions on the impact of open source software on market competition. Market evolution is estimated and forecasted by applying the Lotka-Volterra model, which describes the competitive interaction of species for a common supply. Genetic algorithms are also deployed for the estimation of the model's parameters.Findings suggest that Linux can survive competition, even in a highly concentrated market, while Mac OSX is mostly benefited by the existence of Linux. As one step further, the study performs a sensitivity analysis of the possible effects on market structure induced by a rise in Linux adoption and identifies the conditions under which market structure can dramatically change, even to a competitive one. Results can provide valuable inputs for managerial decisions and strategic planning to the players of software markets
