Making New Year's resolutions? At the website Stickk.com, people set a goal in a specific a time frame and sign a commitment contract that binds them to meeting it.
Then they pick an incentive -- an amount of money or social penalty they will have to pay if they fail -- and a "referee" to monitor their progress and verify their success.
The site was co-founded by Yale University economist Dean Karlan, who has studied how people keep commitments. He talks with Huff/Post50's Laura Rowley about the best ways to keep New Year's resolutions.
