Ultimately, what this paper means to me is that there is evidence (based on simplified conditions, granted) that people collaborate better when they believe they will receive a fair share of the outcome. This makes a lot of sense to me, especially when comparing to real life.<p>For example, why is it that in many cases it is the small startup that creates innovative new technologies compared to large and well funded established players? I guess there are many factors at play, but I would argue that at least one factor relates to a more successful collaboration within the smaller environment, which in part is sourced upon the fact that there is promise of a higher payout in the case of success (equity as part of the salary).
