Economists specialize in pointing out unpleasant trade-offs - a skill that is on full display in the health care debate. We want patients to receive the best care available. We also want consumers to pay less. And we don't want to bankrupt the government or private insurers. Something must give.
Serial tasking is hard because switching tasks is hard, even when the tasks are easy and similar. In some experiments, bilingual speakers are asked to read out numbers, first in one language and then midway in another language. They often stumble at the switch, taking many tries before they hit their stride again.
If you send out one coupon with a deadline of a week and another that must be used within the next month, you end up having more redemptions with the one week deadline. It's really amazing. With the month deadline you have four times as much time, but people tend to say they'll use it in a few weeks' time and then they don't do it.
Our outrage at inequality is primal. But primal emotions are not always noble ones. Of course, when I see a colleague receive some award, I covet it. But this is not me at my best, and these are not the feelings we would instill and promote in our children.
No one would say, 'Hey, I think this medicine works, go ahead and use it.' We have testing, we go to the lab, we try it again, we have refinement. But you know what we do on the last mile? 'Oh, this is a good idea. People will like this. Let's put it out there.'
Eat better or work out more, and you'll see the benefits weeks, months or years down the road. Sleep more, and you'll see the benefits tomorrow.
Our soft hearts are what tell us that, whatever the circumstances of birth, everyone must be given opportunities to do well.
Organizations talk about spending their lives firefighting - dealing with the next problem without having the bandwidth to deal with what is down the pipeline. I think most of the poor have that problem.
I worry about growing income inequality. But I worry even more that the discussion is too narrowly focused. I worry that our outrage at the top 1 percent is distracting us from the problem that we should really care about: how to create opportunities and ensure a reasonable standard of living for the bottom 20 percent.
Maybe poverty is a special case of something else. That something else is 'scarcity,' and anyone who has the experience of 'having very little' experiences the same psychology.
Time can be dissected easily: an hour can be cut up in many ways. Fifteen minutes on this memo, a five-minute walk to another meeting, 30 minutes at that meeting and then 10 minutes debriefing. Oh, and maybe a quick phone call on the walk to that meeting. The busy are expert at dissection: that's how they make it all fit.
We should try to ensure that everyone has a fair opportunity to find a great life. It's a quest that will require political will and ingenious policies. President Obama's proposed expansion of the earned-income tax credit goes in this direction, but we need more.
January is always a good month for behavioral economics: Few things illustrate self-control as vividly as New Years resolutions. February is even better, though, because it lets us study why so many of those resolutions are broken.
Eat better or work out more, and youll see the benefits weeks, months or years down the road. Sleep more, and youll see the benefits tomorrow.
