This study investigates the origins of disruptive innovation.

CCS (carbon dioxide capture and storage) is an issue which has received increasing attention in the debate on climate change over the last several years because of its relative technical simplicity and very large potential in reducing carbon dioxide emissions. The absence of secondary benefits...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

We consider the current bipartite graph of German corporate boards and identify a small core of directors who are highly central in the entire network while being densely connected among themselves. To identify the core, we compare the actual number of board memberships to a random benchmark,...
