Abstract: | Privacy has been recognized as an important topic in the Internet for a long time, and technological developments in the area of privacy tools are ongoing. However, their focus was mainly on the individual. With the proliferation of social network sites, it has become more evident that the problem of privacy is not bounded by the perimeters of individuals but also by the privacy needs of their social networks. The objective of this paper is to contribute to the discussion about privacy in social network sites, a topic which we consider to be severely under-researched. We propose a framework for analyzing privacy requirements and for analyzing privacy-related data. We outline a combination of requirements analysis, conflict-resolution techniques, and a P3P extension that can contribute to privacy within such sites. |

Abstract: | Strategic patenting is widely believed to raise the costs of innovating,especially in industries characterised by cumulative innovation. This paperstudies the effects of strategic patenting on R&D, patenting and marketvalue in the computer software industry. We focus on two key aspects:patent portfolio size which affects bargaining power in patent disputes, andthe fragmentation of patent rights (.patent thickets.) which increases thetransaction costs of enforcement. We develop a model that incorporates botheffects, together with R&D spillovers. Using panel data for the period 1980-99, we find evidence that both strategic patenting and R&D spilloversstrongly affect innovation and market value of software firms. |

Abstract: | The EU regulatory framework for e-communications was adopted by the European Parliament and the Council in 2002, and became applicable from 2003. It has three primary objectives: (1) to promote competition; (2) to develop the single market; and (3) to promote citizens' rights. The European Commission's DG Information Society commissioned London Economics to estimate the level of e-communications investment in the EU and to examine its main drivers as part of a contributio to the Commission's 2006 review of the e-communications framework. This paper outlines some of the findings of that study. The paper provides a description of the process of collecting data on investment in physical infrastructure in the e-communciations sector by country and by sub-sector. It also presents the collected data, showing a decline in overall investment between 2001 and 2003 and a subsequent upturn in 2004. An econometric analysis of the drivers of investment over the period is undertaken, which suggests that better performing regulatory regimes, as measured by an OECD regulatory index, can contribute to higher levels of investment in the sector. |
