These tools are really compelling to me. I was dubious that a carbon tax would be sufficient to motivate substantial change, but it looks to me like a $40/ton carbon tax would drastically improve carbon emissions, and a $100/ton tax would virtually eliminate it. I think as a way of exploring regulatory goals they're fascinating - very few situations does someone set up a simulation of the impact of a law and give laypeople knobs and buttons to play with to see how it would work.
