Efficient tournaments within teams
分析团队或合伙结构中，仅依据部分且带噪音的排名（谁的努力排第一）来设计合同，实现所有成员的一阶最优努力水平，并仅在成员间分配产出。
We analyze incentive problems in team and partnership structures where the only available information to condition a contract on is a partial and noisy ranking which specifies who comes first in efforts among the competing partners. This enables us to ensure both first‐best efficient effort levels for all partners and the redistribution of output only among partners. Our efficiency result is obtained for a wide range of cost and production functions.
