We derive policy rules for a highly aggregated fossil-based world economy with two competing stochastic thresholds or tipping points. Current production generates emissions that add to a stock of GHGs that affect the probability distribution of hitting a climate threshold with severe...

Theoretical analysis and empirical evidence show that leadership behavior in climate policy through increased abatement efforts or international transfers cannot be expected to be very successful. In this paper we instead show that pioneering activities, which are based on green technological...

There is currently much hope about environmental innovation and green technologies, notably as a response to the threat of climate change. This paper offers a critical perspective on the role of technological innovation to solving environmental problems, based on considering empirical economic...
