英文摘要：
  The accumulation of individual fitness or wealth is modelled as a population game in which pairs of individuals are recurrently and randomly matched to play a game over a resource. In addition, all individuals have random access to a constant background resource, and their fitness or wealth depreciates over time. For brevity we focus on the well-known Hawk-Dove game. In the base-line model, the probability of winning a fight (that is, when both play Hawk) is the same for both parties. In an extended version, the individual with higher current fitness or wealth has a higher probability of winning. Analytical results are given for the fitness/wealth distribution at any given time, for the evolution of average fitness/wealth over time, and for the asymptotics with respect to time and population size. Long-run average fitness/wealth is non-monotonic in the value of the resource, thus providing a potential explanation of the curse of the riches.

中文摘要：
个人健康或财富的积累被建模为一个群体博弈，在该博弈中，成对的个人被重复和随机匹配，以在资源上玩一个博弈。此外，所有个人都可以随机获得固定的背景资源，他们的健康或财富会随着时间的推移而贬值。为简洁起见，我们将重点介绍著名的鹰鸽游戏。在基线模型中，双方赢得一场战斗的概率（即双方都玩鹰牌）是相同的。在扩展版本中，当前健康状况或财富较高的个人获胜概率较高。给出了任意给定时间的适应度/财富分布、平均适应度/财富随时间的演化以及关于时间和人口规模的渐近性的分析结果。长期平均健康/财富在资源价值上是非单调的，因此提供了财富诅咒的潜在解释。
