| Abstract: | This paper discusses measures of Internet quality and availability used and usable in the analysis of the so called digital divide. The usage of the share of Internet users in the population - widely used in economic analysis - can easily be misleading in this debate. Based on this measure one might get the idea that the digital divide is narrowing, as some industrialized countries are already close to a share of 100 % Internet users in the population, while the ratio of Internet users to total populations is still growing for developing countries. I argue that one should focus more on the study of Internet quality and quantity provided in a demand and supply model of infrastructure. To this end, I introduce a new latency-based measure to judge the quality of Internet, based on a novel data set, and compare it to related measures. The results indicate that it may indeed be useful to measure Internet quality across countries. The possibility to examine the effects of different determinants on individual quantiles is particularly interesting. ICT investment appear to be stronger correlated with lower latency in the upper part of the distribution, while the effect on the lower part is less pronounced. In addition we find that population density is an important determinant of latency - an argument which is brought up in the theoretical discussion on ICT investment but - to my knowledge - not found empirically to date. -- |

| Abstract: | Service networks can be considered to be open innovation systems. It has led to research on the structure of these networks, concentrating on the static network topology and its effect on innovation. However, the research misses the changes of network positions over time. In this paper, we examine the changes of nodes¡¯ positions in a software service network. The software service network has been built from empirical data. In this network, a node represents a Software-as-a-Service (SaaS) service and a link denotes a re-use of existing software services through a new service. Our results suggest that: first, software services undergo life cycles in their network positions; second, some software services achieve to hub position in their life cycle while others a core position; and third, an innovation trend appears at service category level not just by a single service. These results imply that innovation studies should not only consider static network positions and topologies but also trends of changing positions within the network. |

| Abstract: | We argue that the use of online networks may threaten subjective well-being in several ways, due to the inherent attributes of Internet-mediated interaction and through its effects on social trust and sociability. We test our hypotheses on a representative sample of the Italian population. We find a significantly negative correlation between online networking and well-being. This result is partially confirmed after accounting for endogeneity. We explore the direct and indirect effects of the use of social networking sites (SNS) on well-being in a SEM analysis. We find that online networking plays a positive role in subjective well-being through its impact on physical interactions, whereas SNS use is associated with lower social trust. The overall effect of networking on individual welfare is significantly negative. |

| Abstract: | Cloud computing is changing the way computing is undertaken. It provides the ability to access IT resources on demand without the need for significant capital expenditure, thereby lowering the entry barriers for new entrants in multiple sectors. Cloud computing has thus become a platform for innovation. This report presents the concept of cloud computing, the services it provides and deployment models, and thus give a clear overview of what it is and what it is not. It provides an overview of how cloud computing changes the way computing is carried out, and evaluates the impacts of cloud computing (including its benefits and challenges as well as its economic and environmental impacts). Finally, the report discusses the policy issues raised by cloud computing and the role of governments and other stakeholders in addressing these issues. |
