I've had this idea a long time ago and in fact I still use it. If I need motivation to go to the gym often I would set up an arrangement with someone whereby I'm supposed to go workout 3 times a week. For every time I don't go, I have to hand off $20. I found that this worked really well when I did it with my mom since I did this for a 4-5 months and I only missed two or three workouts when I happened to be really tired/out of it. I always recommend this to people who need motivation. Losing $20 for being lazy is quite painful... Posted November 12, 2007 6:56 PM

Pre-commitment strategies, such as the contract proposed by the Yale researchers, are prominent in much of the literature on addiction. They are thought to be effective ways of addressing periodic failures of self-control. Some believe such lapses are the cause of addictions, such as gambling, drugs, alcohol and food (obesity, bulimia, etc). Such a perspective is evident in the Diagnostic and Statistical Manual published by the American Psychologists Association. An alternative explanation (developed by Gary Becker and Kevin Murphy) is that addicts are economically rational, farsighted and in control but their objects of desire are characterized by inter-temporal complementarity: the more of them you consume today the more you will want to consume tomorrow. I think that their rational addiction model is a more parsimonious explanation of 'addiction' but there are stylized features of addiction that it apparently does not explain (e.g. periodic binges). My problem with the loss of self-control hypothesis this is that it relies completely on self-reporting. People are defined as having lost self-control when they say that's what happened to them. They are presumed not to lie, even though 'addicts' would have a clear incentive to do so. Lying would help to avoid being classified as selfish and/or irresponsible. This is on the assumption that such a classification is less socially damaging than simply being classified as suffering from a 'sickness' (i.e. the loss of self-control).

Is this really a good empirical test? The problem is that these contracts only make the incentive bigger, they don't do anything else to help somebody change. If somebody *truly* wants to change but can't, then they already have an incentive, and the incentive isn't doing the job. Will making it bigger help? I don't know, maybe, maybe not. It's a test of seriousness, but I'm not sure the larger incentive is all that meaningful And bear in mind that the incentive offered here is *purely* negative. So a rational utility maximizer would only take this deal if they judged that it increased their chances of success by enough to offset the risk of losing the money. Seems like a dicey proposition to me. The bigger the incentive the money provides (and thus the more likely it actually improves outcomes), the greater the potential loss that needs to be offset. The other problem with using this for weight loss is that (as nearly anyone who actually has problems with obesity can tell you) it's not nearly as hard to take a bunch of weight off, as it is to *keep* it off. millions of people lose weight, but something less than 5% of the people who lose >40lbs or so actually keep from regaining *all* of it within a few years. If they are setting these up as short term loss contracts rather than as long term maintenance contracts, it's just giving people incentive to *damage* their health (since losing weight and gaining it back is generally worse than never losing it).

Steven King already thought of this. "Quitters, Inc." is about a company where if you don't quit smoking/overeating/whatever, they cut a finger off your wife's hand. It works. Posted November 28, 2007 9:30 AM
