The geography of .pt top level domain. The internet diffusion in Portugal and its implications for the decrease of spatial disparities.

The radical role of information and communication technology (ICT) is one of the most visible topic in the media today and seems to grow from day to day, as well as telecommunications are gradually becoming the central infrastructure tying together our society. The advent of these technologies during the past decades, and their widespread use, is radically transforming the dynamics of communication and our understanding of spatial relationships (by the reduce of distances and the increase of accessibility to information and new services). If there are many studies, attempting to show how city management and regional development policies can creatively address the complex linkages between ICT and urban and regional prosperity (influencing the objective of increasing urban living conditions, combating inwardness, promoting employment and economic competitiveness and supporting social integration policies), there are also many authors arguing that electronic communications reinforce existing patterns of physical communication rather than create new patterns. These suppositions are usually theoretical discussions, that needs to be rigorously tested with empirical analysis and comparative perspectives. The main objective of this paper is precisely to present a detailed study about Portugal, with the purpose of questioning the decrease of spatial disparities due to the potential influence of ICT’s. This research is mostly based on new spatial statistics, collected, mapped and analysed in order to understand the diffusion process of the most sophisticated, diverse and capable telecommunication infrastructures, and consequently verify the plasticity of space throughout Portugal, and the ways it has been stretched or compressed. We will be focusing the globally-interconnected set of computer networks, known as ‘The Internet’, which is widely used by millions of individuals, firms and institutions every day, as a way to get into an invisible domain, popularly known as cyberspace, in order to seek information, marketing new services and products, and as means of communication within and between organizations. We believe that this invisible territories of the cyberspace do have a geography and, in an attempt to reveal its topography, we should analyse the spatial patterns of the ownership of Internet space. Despite the rapid growth of Internet in recent years, and the gradually recognition of its implications, there is a lack of knowledge about its geographic diffusion and its attendant implication for regional urban development. Specially in what concerns to its effective role to generate substantial adjustments on traditional portuguese regional dichotomies, or instead, if it is an unexpected contribute to reinforce territorial disintegration tendencies. For the empirical research will try to find links between cyberspace and the portuguese physical geography. In our opinion a good way to achieve this goal is discovering which and where are located the portuguese entities that recognize the importance to distribute globally information, about their activities and services, through the use of the Internet. For that we will explore the compulsory registration of all .pt domain names on one single institution –Foundation for National Scientific Computing- (FNSC), which performs all the registration services for the geographical .pt domain.

Technological change, accident prevention and civil liability

The improvement of accident prevention technology in many fields of social life has spurred new challenges to the doctrinal tools of fault and strict based civil liability in the law of torts. Amid these challenges lies the identification of the proper scope of the respective criteria of liability in a changing factual environment, their suitability as doctrinal tools, as well as their actual application to concrete cases given the amount of information which would be needed to render adequate judgments. Precedents and old laws should be assessed with caution, taking into account the tacit cost-benefit analysis embedded in them, for they may or may not serve the interests of welfare maximization in an environment with constantly renewed accident prevention technology

A Panel Data Investigation of Real Exchange Rate Misalignment and Growth

The paper investigates the role of real exchange rate misalignment on long-run growth for a set of ninety countries using time series data from 1980 to 2004. We first estimate a panel data model (using fixed and random effects) for the real exchange rate, with different model specifications, in order to produce estimates of the equilibrium real exchange rate and this is then used to construct measures of real exchange rate misalignment. We also provide an alternative set of estimates of real exchange rate misalignment using panel cointegration methods. The variables used in our real exchange rate models are: real per capita GDP; net foreign assets; terms of trade and government consumption. The results for the two-step System GMM panel growth models indicate that the coefficients for real exchange rate misalignment are positive for different model specification and samples, which means that a more depreciated (appreciated) real exchange rate helps (harms) long-run growth. The estimated coefficients are higher for developing and emerging countries.long-run economic growth, real exchange rate misalignment, panel data analysis and System GMM
