Commitment bonds have helped me live a happier life in 2007. I committed to exercise more (and for the first time can do 10 pull ups). I committed to read more (and have had the pleasure of reading more than 40 novels). But most importantly, I committed to lose some weight and keep it off. I put $500 at risk a week and you can see the results in the following graph:

The upper blue line shows my “Goal Weight”, the weight that I can’t exceed without losing money. The red-line is my daily weight. For the first time in several attempts, I’ve stopped the yo-yoing. So far, I’ve lost the weight and it hasn’t cost me a penny.
I have hopes that StickK will be an engine for finding out what kind of incentives work the best and for whom.
Before I got tenure at my first job, I was worried about my habit of not finishing papers quickly enough. I tried to enlist a colleague in a scheme whereby I would pay him
ReplyDelete$2,500 * (X-Y) * 1(Y<=X),
where X was my target number of papers submitted by some date and Y was the number I actually submitted.
My University of Chicago-trained senior colleague demurred, to my great shock on the grounds that he'd feel badly if I had to pay him!
Anyhow, great idea, Ian!
