(1) Joshua Gans identifies in Dubner and Levitt an odd inconsistency that I’ve identified more broadly: those who go on and on about how people respond to incentives when they’re making a pro-free-market argument suddenly seem to lose all faith in the power of incentives when the goal is to induce more environmentally friendly behavior:
But come on. Isn’t the whole point of the Freakonomics project that prices work and behaviour changes in response to incentives? Everywhere else, a few pennies will cause massive consumption changes while when it comes to a carbon price, it is all too hard.
(2) Ryan Avent makes a general point about people who dismiss cap-and-trade as too hard, then promote something else that only seems easier because you haven’t thought it through. I agree with him about the carbon tax issue; and while I hadn’t thought about applying the same principle to geoengineering, he’s completely right. Having somebody--who? The United States? The United Nations? The Coalition of the Willing?--pump sulfur into the atmosphere through an 18-mile tube, or cut off sunlight with a giant orbital mirror, would either (a) require many years of hard negotiations or (b) quite possibly set off World War III. If it’s (a), why is that so much easier than a global agreement on emissions? (Which, as Brad points out, really would only have to involve four big players.)
(3) Andrew Gelman poses a question:
The interesting question to me is why is it that “pissing off liberals” is delightfully transgressive and oh-so-fun, whereas “pissing off conservatives” is boring and earnest?
I have a theory here, although it may not be the whole story: it’s about careerism. Annoying conservatives is dangerous: they take names, hold grudges, and all too often find ways to take people who annoy them down. As a result, the Kewl Kids, as Digby calls them, tread very carefully when people on the right are concerned — and they snub anyone who breaks the unwritten rule and mocks those who must not be offended. Annoying liberals, on the other hand, feels transgressive but has historically been safe. The rules may be changing... but it’s been that way for a long time.
