A global planning problem is analyzed for extracting an exhaustible resource like oil when resource extraction - the only source for current consumption - also generates additions to the stock of GHGs that influence the likelihood of hitting a threshold representing climate change. We derive...

Discounting in the presence of catastrophic risk is a hotly debated issue, in particular with respect to climate change. Many scientists and laymen concerned with potentially catastrophic impacts feel that if an increase in the discount rate drastically increases the likelihood of catastrophic...

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...
