My friend and coauthor Joshua Gans has an article in the Drum about the benefits of pricing carbon over the Opposition's grab-bag of mandates and subsidies. He concludes:
The point is that this game could go on and on with very little impact and possibly negative impact on total emissions. And there is example after example of this. Think of the taxes required to employ all the inspectors and personnel to ensure that regulations are doing what you wanted without unintended consequences. Sure, it can be done but you will need a government that would make Lenin blush to make it happen.
Contrast that with a carbon price - by tax or trade. That requires none of this because it hits directly on the problem: emissions create external costs so we need everyone to build that cost into their decision-making. The problem is, as right-wing economist Frederick Hayek pointed out, that no-one has the information required to plan out what individuals might do themselves. By placing the decisions of environmental management in the hands of the people, you can let things work themselves out in a way the heavy-handed Government involvement cannot.
It is ironic that on climate change policy, politics are in the bizarro-world where the supposedly anti-market Greens side with Hayek while the supposedly pro-market Coalition sides with Lenin. The economic evidence strongly suggests that the Greens policies match their goals while the reverse is true for the Coalition. I can’t parse the dual hypotheses that either the Coalition just deny economic evidence or that they actually want more emissions and handouts to business. Perhaps one of their number can enlighten us.
