The effect of the stake size on the evolution of fairness

作者：

Highlights：

• An evolutionary model is proposed to investigate the stake-size effect on fairness.

• The average offer and the average demand are calculated for two update rules.

• Increasing stake size makes populations closer to the rational selfish strategy.

• The largest stake promotes tolerance to an extreme.

• The intermediate stake or the largest stake promotes generosity to an extreme.
