International diffusion of energy-saving technologies has received considerable attention in recent energy and climate economics studies. As a helpful methodological complement to the existing large-scale CGE/IAM–based modelling for energy and climate policy studies, this paper contributes to...

We develop a model of endogenous network formation in order to examine the incentives for R&D collaboration in a mixed oligopoly. Our analysis reveals that the complete network, where each firm collaborates with all others, is uniquely stable, industry-profit maximizing and efficient. This...

In this paper, we compare two different representations of Framework Programs as affiliation network: “One-mode networks”' and “Two-mode networks”'. The aim of this article is to show that the choice of the representation has an impact on the analysis of the networks and on the results...

Novel early stage ideas face uncertainty on the expertise needed to elaborate them, which creates a need to circulate them widely to find a match. Yet as information is not excludable, shared ideas may be stolen, reducing incentives to innovate. Still, in idea-rich environments inventors may...

We develop an endogenous growth model with capital, labor and energy as production factors and three productivity variables that measure accumulated innovations for energy production, energy savings, and neutral growth. All markets are complete and perfect, except for research, for which we...

We study the interactions between technological innovation, investment in human capital and child labor. In our setting new technologies require new skills and new skills can be developed only through schooling. In a two-stage game, first firms decide on innovation, then households decide on...

In the last fifteen years, income differences among European Member States have been strongly narrowing while the process has been matched with a widening of the inter-regional variance within single countries. Traditionally, regional economic disparities in Europe have been ascribed to...

A suitable strategy for achieving sustainable development is to foster environmental innovations. Environmental innovations, however, suffer from so-called "double externalities", because apart from innovation spillovers they also improve the quality of public environmental goods, which can be...

We develop an economic partial equilibrium model for energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. Our model reproduces the learning curve typical for (bottom-up) energy system...

Environmental policy instruments have an impact on the incentives to invest in environmental R&D and this link should deserve careful consideration when introducing new instruments. Some authors argue that environmental taxes and tradable permits have rather comparable impacts on environmental...
