| Abstract: | We discuss the issue of a possible abolition of network neutrality and the introduction of paid prioritization by residential broadband access networks.We show that, in short run analysis where bandwidth is fixed, and in the absence of congestion, network neutrality tends to maximize total surplus. When an ISP violates network neutrality and invests the extra profits to bandwidth expansion, the presence of more bandwidth alleviates the allocative distortion, and can even reverse it. We also discuss the network neutrality issue under the assumption of congestion, and characterize the set of utility functions for which network neutrality is optimal, as well as utility functions where it is optimal to prioritize. Finally, we review regulatory rules in the United States on network neutrality. |

| Abstract: | This article investigates the relationship between Information Technologies (IT), new organizational practices and workers' contextual performance in the European context. Our empirical results are based on data about more than 11000 employees from 16 European countries in 2005 and more than 16000 in 2010. First, we find asymmetric effects of IT use. Internet use is, indeed, positively related to all aspects of contextual performance in 2010, while computer use has been positively associated with contextual performance in 2005 but not in 2010. Second, we find that most of the considered new organizational practices have a positive relationship with employees' contextual performance. |
| Abstract: | Cet article analyse les relations entre les Technologies de l'Information (TI), les nouvelles pratiques organisationnelles et la performance contextuelle des employés dans le contexte européen. Nos résultats empiriques sont basés sur des bases de données concernant plus de 11 000 employés de 16 pays européens en 2005 et plus de 16 000 en 2010. Premièrement, nos résultats soulignent des effets asymétriques de l'usage des TI. L'usage d'Internet est, en effet, positivement lié à tous les aspects de la performance contextuelle en 2010, tandis que l'usage de l'informatique est associé positivement seulement à la performance contextuelle interpersonnelle en 2005. Deuxièmement, nous constatons que la plupart des nouvelles pratiques organisationnelles considérées ont une relation positive avec la performance contextuelle des employés. |

| Abstract: | This study examines the impact of firm resources on ICT adoption by the Turkish business enterprises using firm level data. ICT adoption is measured at three levels: The first level is technology ownership. The second level is the presence of enterprise resource planning (ERP) and customer resource management (CRM), and the third level is the use of narrowband and broadband technologies. The effects of the three main features of each technology level, which are complementarity, specificity, and the complexity, are analyzed by using firm level data in Turkey. This study has three main conclusions. As for the complementarity, firm's resources play an important role in the adoption of technology while advancing from single technology to the multiple ones. Further, in the use of specific technologies such as ERP and CRM, firm resources generate differential effects between those technologies. Finally, the use of simple technologies does not require the same amount of firm resources as complex technologies. |

| Abstract: | Luxury is a complex industrial activity whose products combine strong vertical differentiation and a meaning value for the consumer. Luxury offers experiences, the economy of which is based on signalling. This gives rise to intense intangible investment internalized by trademark law and vertical restraints in distribution. However, the extent of the added value and the power of externalities associated with communication generate many sources of free-riding. Using the tools of industrial economics, this article analyses how the digitization of information and transactions creates new forms of free-riding in relation to luxury brands. Identifying vertical disintegration as a major source of free-riding, it calls for improved internalization of the enforcement of trademark law by all players in the digital value chain. |

| Abstract: | The aim of this paper is to explore the relationship between the adoption of Information Technologies (IT) and the adoption of New Organizational Practices (NOP) in the context of an emerging country (Tunisia). Based on face-to-face questionnaire, to a random sample of 175 Tunisian manufactures, and using an ordered logit model, our empirical results show a significant link between IT adoption and NOP. We show that the complementarity is strengthened when the technology evolves. Adoption and usage of latest technologies are pushed by the prior adoption of NOP. |
