本文考察了一种重要的农业非市场制度--劳动分享的可替代性、生产率、效率和演化。对亚马逊流域轮垦者随时间推移进行森林砍伐的实地数据分析表明，（a）家庭、雇佣和合作劳动是完美的替代品，雇佣和合作劳动的生产率相同，而且都比家庭劳动的生产率高;（B）劳动力市场和劳动力共享的结合使得生产率调整后的总劳动力使用不受家庭和网络禀赋的约束（即，有效的劳动力分配）;当劳动力构成受到网络禀赋和流动性的约束时，信贷政策会改变劳动力构成和劳动力网络的形成。
This article examines the substitutability, productivity, efficiency, and evolution of an important agrarian nonmarket institution—labor sharing. Analysis of field‐level data on forest clearing through time among Amazonian shifting cultivators reveals that (a) family, hired, and cooperative labor are perfect substitutes, and hired and cooperative labor are equally productive, and both are more productive than family labor; (b) the combination of labor market and labor sharing makes productivity‐adjusted total labor use unconstrained by household and network endowments (i.e., efficient labor allocation); and (c) as labor composition is constrained by network endowments and liquidity, credit policies alter both labor composition and labor network formation.
