We develop a simple model of managing a system subject to pollution damage, such as climate change, under the risk of an abrupt and random jump in the damage function. The model allows the full dynamic characterization of the optimal emission policies under uncertainty. The results imply...

We give a full characterization of the open-loop Nash equilibrium of a nonrenewable resource game between two types of firms differing in extraction costs. We show that (i) there almost always exists a phase where both types of firms supply simultaneously, (ii) when the high cost mines are...
