A theoretical framework is proposed for the better understanding of the OSS global diffusion. Following a case study approach, the Apache web server's market potential is estimated, forecasted and examined in terms of the socio-economic factors determining its diffusion, across different economic environments in developed versus developing countries. Market saturation is explored under the prism of three theoretical perspectives: the institutional, the endogenous and the exogenous growth theories. Findings suggest that Apache market saturation levels depend on both endogenous and exogenous to a country factors and that institutional quality plays an important role to the market potential. Implications for theory and public policy are discussed. 相似文献

This article examines the impact of input prices on an entrant’s make-or-buy decision and on the subsequent social welfare
level for three alternative models of downstream competition. For each particular model, it derives the range of input prices
that induce the entrant to undertake: (a) the productively efficient make-or-buy decision; and (b) the socially optimal make-or-buy
decision. The main conclusion of this article is that the entrant’s efficient make-or-buy decision is always socially optimal
in the case of the Hotelling model, is socially optimal for the set of input prices that induce the entrant to undertake the
efficient decision in the case of Cournot competition and is not necessarily socially optimal in the Bertrand vertical differentiation
model. Last, this article examines the conditions under which the efficient and/or socially optimal make-or-buy decision undertaken
by an entrant fulfills the regulatory two-fold goal of promoting service-based competition and encouraging facilities-based
competition. Therefore, this article also provides the optimal access pricing policy that results in the best feasible outcome
in terms of social welfare, productive efficiency, competition level and investment level for a given downstream competition
model. 相似文献

The current regulatory framework in the European NGA market provides the basic principles for the gradual migration from service-based competition over the legacy copper access networks to facilities-based competition over fiber-based Next Generation Access (NGA) networks. This paper initially reviews the related literature and shows that: (i) an unbundling policy that boosts entry by alternative operators promotes service-based competition but provides operators with disincentives to invest in network upgrade; (ii) there is no consensus about the optimal regulatory policy that promotes competition and encourages investments in NGA networks; and (iii) the reviewed research articles are not consistent with the current regulatory framework in the European NGA market in terms of both the evolution of the regulatory goals over time and the recommended regulatory settings. This paper aims to propose a novel approach in order to effectively meet the current regulatory goals using the recommended settings. It is shown that the proposed approach, which is based on the basic principles governing a Credit Default Swap (CDS), provides an effective migration path towards facilities-based competition over NGA networks. 相似文献
