Richard Thaler introduced at UCSD his new book on Libertarian Paternalism. This seems to be a strange title for a Chicago guy (and he gets some heat from his colleagues) and maybe even an oxymoron (which it's not). The talk was, in short, fascinating. The basic idea is that people are not perfectly rational in every single decision they make (which may sound suspicious to economists, but seems trivial for people), and thus they make mistakes. They even make mistakes in a predictable way. They regret these mistakes. The most frequently used example is 401(k) plan: usually, these are opt-in plans - you get in, save money, your employer gives some more money and life is beautiful. Except that people don't opt-in for some reason. Presumably, they face tough choice (easily 80 different hedge funds), they don't have time to thing and decide etc.They end up not only losing possible returns on their own savings, but also employer's contribution. But if they have the opt-out choice, they stay in and save. The designer (government, employer) who has interest of such people in mind might find useful to use opt-out instead of opt-in system. Everybody is free to go (libertarian), if they want to, but if they don't do anything, they are in (paternalism).
The idea of a design of a system that does something for you if you choose not to do anything, but allows you to leave whenever you go will hopefully get more attention in the future. It does not restrict your freedom (costs of saying "no" are negligible), yet it makes the choice for many people easier and they end up satisfied with this decision.
The idea is not limited to 401(k) plans. Among other fascinating examples, I like the one that saves lives and not money. It's the organ donation status. In some countries (Austria, Belgium, Denmark, Finland, France, Italy, Luxemburg, Norway, Singapore, Slovenia, and Spain), everybody is presumed to be willing to donate his/her organs in case of death - opt out is easy. In other countries (USA), one has to opt-in to be considered a donor.So what?
The result is that in “presumed consent” nations over
90 percent of people make their organs available for donation, whereas in the United
States, the corresponding number is below 20 percent.
( (Cass R. Sunstein and Richard H. Thaler)
Simple policy, simple decision and huge impact.
Example like allow me to hope that libertarian paternalism is a future of applied economics. Previously, government simply regulated (enforced, restricted, forbid or taxed) a behavior. We are at the point in which we understand subtler errors of human behavior. And we can use this knowledge to design existing (or even new) regulations better for everybody, especially if some choice about the design needs to be done. The nice libertarian touch is that nobody is forced to do anything, as long as costs of saying "no" are trivial, which they should.
Anyway, if you have an hour to spare, you can listen to Richard Thaler himself at a very similar talk at EconTalk.org
