I’ve just published a piece in Aeon (an excellent and free online magazine) drawing on the analysis in my (about to be published) book Economics in Two Lessons. I make the case that carbon pricing, whether through a tax of an emissions trading scheme, is the most cost-effective way to stabilize the global climate. Moreover, it’s straightforward to offset any adverse effects on low-income earners, displaced workers and others.

That raises the obvious question: if carbon pricing is so good, why is it so hard to implement, compared to less efficient alternatives like mandatory renewable targets. One factor, which I discuss, is that the creation of property rights over previously open-access resources creates obvious, and often powerful losers.

I was limited by space, so I couldn’t discuss the more puzzling problem of why regulations are more politically salable than prices even in the absence of income effects.
