If investors fear that future carbon taxes will be lower than currently announced by policy makers, long-run investments in green-house gas mitigation may be smaller than desirable. On the other hand, owners of a non-renewable carbon resource that underestimate future carbon taxes will postpone...

Optimal climate policy is studied. Coal, the abundant resource, contributes more CO2 per unit of energy than the exhaustible resource, oil. We characterize the optimal sequencing oil and coal and departures from the Herfindahl rule. “Preference reversal” can take place. If coal is very dirty...
