In the presence of strategic complementarities stemming from peer effects in demand or from technological spill-overs, propagation and amplification mechanisms increase the effectiveness of climate policies. This suggests that climate goals can be met with smaller policy interventions. However,...

We propose a mixture model approach to identify locally optimal technologies and to dissect environmental productivity (output produced per unit of emission) into a technological and a managerial component. For a large sample of plants covered by the EU ETS, we find that the share of plants...

Industrialized countries and emerging economies must cooperate in order to decarbonize the emissions-intensive industrial sector and to limit global warming to 1.5 degrees Celsius. While Germany and the other G7 countries have committed to supporting emerging economies in their efforts to combat...
