How environmental economics saved Christmas

By Gernot Wagner

Art Carden has a great piece on the Grinch saving Christmas,

using Pigouvian taxes and the bargaining business.

But it reminds us again that even Coase missed the mark,

when it comes to things outside of Whoville's small arc.

So to Art's welcome take on a Yuletide tradition,

We humbly append a climate-change addition:

Since Whoville Whos' chanting affects only the Grinch,

Bargaining is the solution that works in a pinch.

Climate's a problem that affects the whole planet,

Coasian bargaining is much too small to span it.

A price on carbon is the better path,

all we need now is the political math.

Failing that, to be sure, we have the EPA,

not a first-best choice, still it may win the day.

To save the world's Whovilles, we need a solution

that in the end puts a firm limit on carbon pollution.

Cap and trade is the most certain way

to give every Who joy on this and future Christmas Days.
