The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

It is widely recognized that technological change has the potential to reduce GHG emissions without compromising economic growth; hence, any better understanding of the process of technological innovation is likely to increase our knowledge of mitigation possibilities and costs. This paper...

This paper elaborates on the recent race to sequence the human genome. Starting from the debate on public vs. private research arising from the genome case, the paper shows that in some fundamental research areas, where knowledge externalities play an important role, market and non-market...
