Mark Kleiman (hat tip Brad DeLong) says more clearly what I tried to say a while back: cost-benefit analysis of regulations has a curious way of nailng the costs and underestimating the benefits. He focuses on three points:
- Traditional CBA counts all dollar benefits equally, despite the fact that the marginal utility of a dollar depends a lot on who is getting it; a dollar more for a poor person provides a lot more utility than a dollar more for a rich person.
- Long-term or uncertain benefits, no matter how large (like preventing the inundation of every coastal city) are typically discounted down to zero.
- Benefits that are difficult to quantify because there is no market for them (like feeling better because you are healthy) never get counted. (This is the one I know best because it’s one of the things my wife specializes in.)

Felix Salmon has a good example of why disclosure (the preferred consumer-protection regime of free-market conservatives and bankers) doesn’t work, courtesy of Ryan Chittum. The topic is no-interest balance transfers offered by credit card companies.
As Salmon points out, most people probably realize what the game is. That is, most people know that banks aren’t in the business of lending money for free; they know that the bank is betting that it can raise the interest rate before they pay off the balance. It’s possible that you will end up getting a free loan: “If you’re smart and disciplined and lucky, you might be able to game the system and pay no interest at all on that balance. Bank of America, for its part, does its very best to make you think that you’ll be able to do just that, essentially getting one over on The Man.” But the bank knows it has the numbers on its side; and most consumers know it too, because they know that’s the only reason the bank would make the offer.
