Environmental Economics - Should a carbon tax vary over the economic cycle?

Should a carbon tax vary according to the stage of the economic cycle?

Would such a strategy help to mitigate some of the risks of emissions reductions on jobs and real incomes during tough economic times?

This is the main argument of research presented in this VoxEU paper.

Economists Ghassane Benmir, Ivan Jaccard and Gauthier Vermandel make the case that the optimal carbon tax should vary substantially over the economic cycle.

It is the sort of argument that would classify as excellent evaluation when discussing some of the potential trade-offs between policies - in this case, between environmental policies and their short-term macroeconomic impact.
