In Are You Fully Charged? Tom Rath quotes a study on Pro Social Incentives for teams. I had come across a similar idea presented before in Drive by Dan Pink. My own experiences participating in sporting teams and at ThoughtWorks further emphasized the argument for it.
When motivating ourselves we are much more incentivised if the reward being offered for our work benefits others through our giving rather than receiving a reward ourselves.

Are You Fully Charged? by Tom Rath
From my personal experiences I have found my work to be much more rewarding when the result of my work allows me to provide a benefit to another person and not just to myself. That said, I believe that a Pro Social Incentive is most effective when their is already some baseline of incentive for the individual already established, i.e. Maslow's Hierarchy of Needs.
