We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

Evolutionary and environmental economics have a potentially close relationship. This paper reviews past and identifies potential applications of evolutionary concepts and methods to environmental economics. This covers a number of themes: resource use and ecosystem management; growth and...

In the last decades the world changed dramatically. From a global point of view three disruptive processes are on their way which can be called revolutionary: a political, a technological and an economic revolution. This paper aims to give an overview when and how these movements started what...

The purpose of this paper is to reach better general understanding of the institutions and processes needed to develop and commercialise nanosciences and nanotechnologies. This knowledge may prove useful to guide the actions of public and private agents. In order to analyse the paths followed in...

This paper locates the notion of technological revolutions in the neo-Schumpeterian effort to understand innovation and to identify the regularities, continuities and discontinuities in the process of innovation. It looks at the micro- and meso-foundations of the patterns observed in the...
