This paper estimates the determinants of labour productivity in European NUTS regions during 1989-1996. Unlike previous studies, which have focussed either on local technological capabilities or on agglomeration economies, we compare three potential explanations of regional advantages:...

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...

The paper examines the key factors influencing the adoption ofe-business technology by SMEs. To this end, the paper draws on a rangeof literatures on the diffusion of new information and communicationtechnologies (ICTs), many of which have hitherto been treated asseparate. The reasons for this...

The paper examines the conditions under which technological successions can occur in the presence ofnetwork externalities. A multi-agent model is developed in which the product designs offered by firmsco-evolve with consumer preferences. Firms compete though product innovation. The...

This paper examines the evolution of networks when innovation takes place as a result of agents bringing together their knowledge endowments. Agents freely form pairs creating a globally stable matching. paired agents combine their existing knowledge to create new knowledge. We study the...

This paper aims at identifying the sources of comparative advantage and the bottlenecksof the Tunisian economy. By using an activity analysis model and yearly data on theinput-output structure and the factor endowments, the paper determines the evolution ofthe potential of the Tunisian economy...
