It would be interesting to ask whether or not the pioneers behind Google, eBay, and Amazon are aware of these theories coming out of evolutionary biology. Reputation is something that is profoundly embedded in our mentality, and we — not just old professors, but everyone — care enormously about it.

Martin picked up on this work and started with a very simple model. It was a kind of numerical score, a label that says how often a person has given in the past. The idea is that my decision of whether to give to that person or not will depend on that score. I give more freely to persons with a high score. I refuse to help persons with a low score. This extremely simple model worked very well and inspired a lot of economists to do many experiments based on it.

If I only give to a person with a high reputation, I channel my help to those who have proved their value for cooperation.

There are now at least ten papers by economists in the works on these topics that I could mention here, but all of them are in the preparatory stage and none has been published.
