From his recent opinion on the health care law, page 24:
To an economist, perhaps, there is no difference between activity and inactivity; both have measurable economic effects on commerce. But the distinction between doing something and doing nothing would not have been lost on the Framers, who were "practical statesmen," not metaphysical philosophers.

On the negative correlation between effort and pay
It would seem natural that in a system where pay is linked to performance, better performers are rewarded more handsomely. Yet, there are plenty of examples where this does not work. If it is difficult to find a metric of performance, then the selected metric may give wrong incentives. The classic example is programmers paid by the number of code lines written, which leads to bloated and confusing code. Another one is with many civil servant jobs where the output is not related to a marketed good. The issue can be so bad that a negative correlation between performance and pay emergences.
Ola Kvaløy and Trond Olsen show that this could happen in another way that is not related to monetary and non-monetary rewards, yet has an impact on intrinsic motivation: weak enforcement probability. Suppose the latter is variable. Then high monetary rewards may be associated with a low probability that the scheme will actually be used. Workers may then just slack off. The above hypothesis is not completely insane, as one can imagine situations where there is moral hazard on the side of the worker, and the work contract tries provide the worker both with incentives and with some insurance. It works also without worker risk aversion if there is limited liability.

SCOTUS on the Health Care Mandate
Well, the Supreme Court said today that the health care mandate is ok. I am no constitutional scholar, but from what I can tell from the news reports, the Court's logic is similar to mine in this old blog post.
Spouses and unemployment duration
When unemployed, some people search more intensely for a new job than others. That will of course depend on their personal circumstances. The urgency of getting some income is obviously more pressing when there is little alternative income, and one such alternative is the spouse.
Stefania Marcassa studies French couples where one spouse works and the other is unemployed. It turns out unemployed men search longer for a job if their spouse earns less, while it is reversed for unemployed women. That turns out to be consistent, in a standard labor search model, with a breadwinner stigma for men. French men do not seems to be able to bear the thought of having a successful wife while being unemployed, while women see no hurry to work if their husband is doing well. Clearly, the sexist ones here are the men.

Is obesity an information problem?
As mentioned yesterday, childhood obesity is a problem that can be reduced by giving more opportunities to be outside and away from the television. But one may also try to combat the problem with information campaigns. One way is to publish dietary information in restaurants, something that even benefits the restaurants, as I reported earlier. But most food is not consumed in restaurants, especially for poor households who also are most likely to be obese. But do such information campaigns really work?
Andres Silva, Marian Garcia and Alastair Bailey show that when news about childhood obesity hit the media in the UK, households change their food habits for the better, and without having an impact of expenses. It is thus possible for the poor to do something about the obesity risk without financial consequences.
The fact that information matters is corroborated in a study by Linda Thunström, Jonas Nordström, Jason Shogren and Mariah Ehmke that shows that people use strategic self-ignorance to make choice they know has bad future implication. Specifically they did an experiment where people could choose meals and obtain without cost calorie information. Most subject chose to remain ignorant and then took in more calories than the enlightened ones.
