In this paper, we extend the Romer (1990) model in two ways. First, we include energy consumption of intermediates. Secondly, intermediates become heterogeneous due to endogenous energy saving technical change. However, aggregate effective capital is still subject to endogenous technical change...

Internet, the fastest growing communications medium or consumer electronic technology, doubles its size every six months. Within a few years the number of citizens in Cyberspace will outnumber all but the largest nations. The borderless world of the Internet extends its reach to all corners of...

The paper analyzes the use of a Multi Agent System for Model Based Diagnosis. In a large dynamical system, it is often infeasible or even impossible to maintain a model of the whole system. Instead, several incomplete models of the system have to be used to detect possible faults. These models...

EC research programmes are promoting collaborative scientific research in general and “integrated Internet-based collaborations” in particular. New intellectual property rights (IPRs) are being developed to ensure the “intellectual property” of newly developed scientific and...

There is growing evidence of international divergence in the performance of newindustries. While the United States is at the forefront of the recent revolution ininformation technologies, European economists and policy makers are concerned thatEurope is falling behind with negative implications...

In this paper we integrate two workhorse models in economics: The monopolistic competition model of Dixit and Stiglitz and the search unemployment model of Pissarides. Information and communication technology (ICT) is interpreted as i) technical progress in the matching function of the...

This paper seeks to assess the importance of country-level determinants in affecting the international competitiveness of a country, defined both by export shares and shares in FDI, within a common framework based on a neo-Schumpeterian approach which regards technology as playing a central role...

The arena of mobile telecommunication in Europe has undergone a technological transition from analogue (first generation) to digital (second generation) technologies. While this transition is immediately attributable to shifts in demand and supply patterns, closer examination reveals that there...

Over the last decade or so, multinational enterprises (MNEs) have shifted from centralised hub structures to multi-hub structures. While these new structures provide greater potential for cross-fertilization of technologies and access to locationspecific competences, promoting effective...

The purpose of this study is to explore the factors that allow firms to benefit from knowledge developed inuniversities and government labs or that drive them to collaborate with these institutions. A number ofstudies have examined this question from various perspectives: the characteristics of...
