英文摘要:
We consider a manager, who allocates some fixed total payment amount between $N$ rational agents in order to maximize the aggregate production. The profit of $i$-th agent is the difference between the compensation (reward) obtained from the manager and the production cost. We compare (i) the \\emph{normative} compensation scheme, where the manager enforces the agents to follow an optimal cooperative strategy; (ii) the \\emph{linear piece rates} compensation scheme, where the manager announces an optimal reward per unit good; (iii) the \\emph{proportional} compensation scheme, where agent\'s reward is proportional to his contribution to the total output. Denoting the correspondent total production levels by $s^*$, $\\hat s$ and $\\overline s$ respectively, where the last one is related to the unique Nash equilibrium, we examine the limits of the prices of anarchy $\\mathscr A_N=s^*/\\overline s$, $\\mathscr A_N\'=\\hat s/\\overline s$ as $N\\to\\infty$. These limits are calculated for the cases of identical convex costs with power asymptotics at the origin, and for power costs, corresponding to the Coob-Douglas and generalized CES production functions with decreasing returns to scale. Our results show that asymptotically no performance is lost in terms of $\\mathscr A\'_N$, and in terms of $\\mathscr A_N$ the loss does not exceed $31\\%$.

中文摘要:
我们考虑一个经理,他在N$理性代理之间分配一些固定的总付款金额,以最大化总产量。第i美元代理商的利润是从经理处获得的报酬(奖励)与生产成本之间的差额。我们比较了(i)管理者强制代理人遵循最优合作策略的{规范性}薪酬方案;(ii)管理者宣布每件商品的最佳报酬的{线性计件工资}补偿方案;(iii)按比例补偿计划,代理人的报酬与其对总产出的贡献成比例。将相应的总生产水平分别表示为$s ^*$、$\\ hat s$和$\\ overline s$,其中最后一个与唯一的纳什均衡相关,我们检查了无政府状态$\\ mathscr A\\N=s ^*/\\ overline s$,$\\ mathscr A\\N\'=\\ hat s/\\ overline s$as$N \\ to \\ infty$的价格限制。对于原点处具有幂渐近的相同凸成本情况,以及对应于库布-道格拉斯和广义CES生产函数且规模收益递减的功率成本情况,计算这些极限。我们的结果表明,对于$\\mathscr A\'\\N$而言,渐近没有性能损失,对于$\\mathscr A\'\\N$,损失不超过31\\%。
