This paper offers a new methodology to identify R&D and innovation clusters, on the basis of a regional analysis of innovation support systems in Portugal. Using a web-based inventory of R&D and innovation agencies, an extensive data base is created. This data set is next analyzed by means of...

In the search for effective pesticide risk management tools, the design of pesticide risk indicators is nowadays receiving increasing attention as a complement to more established regulatory strategies. In the present paper, we apply some recently developed pesticide risk indices and test their...

This paper provides an empirical analysis of decoupling economic growth and energy use and its various determinants by exploring trends in energy- and labour productivity across 10 manufacturing sectors and 14 OECD countries for the period 1970-1997. We explicitly aim to trace back aggregate...

This paper makes use of a new dataset to investigate energy intensity developments in the Netherlands over the period 1987-2005. The dataset allows for a comparison with 18 other OECD countries. A key feature of our analysis is that we combine a cross-country perspective with a high level of...

This paper reviews the empirical literature on growth and convergence that has addressed the importance of spatial factors. An important distinction in this literature is the one between absolute and relative location. The literature on absolute location predominantly uses non-spatial...

Following formal privatisation of farm land and assets in CentralEurope, the change in agriculturalproduction structures has been both more limited and different thanwas initially expected. In this paper, thetheoretical reasons underlying those expectations are reviewed. Analternative...

This paper uses a new dataset derived from a consistent framework of national accounts to compute and evaluate energy intensity developments across 18 OECD countries and 50 sectors over the period 1970-2005. We find that across countries energy intensity levels tend to increase in a fairly wide...

This paper addresses the interplay between economic growth, energy use, change in sectoral composition and technological change, by exploring trends in energy- and labour productivity development for 14 OECD countries and four sectors over the period 1970-1997. A cross-country decomposition...
