摘要

虽然世界上许多穷人摄入的卡路里不足，营养价值低，但关于这可能如何影响他们的行为和生产力的研究却很少。本研究以埃塞俄比亚的一个花卉栽培工厂为背景，通过实地和实验室实验，调查了营养支持计划对行为结果（压力、亲社会、合作和注意力）和生产力的影响。我们发现，随着时间的推移，营养支持可以缓解压力，减少亲社会行为，表现出一种享乐适应模式。我们没有发现劳动生产率提高的证据。

The effects of nutrition support on behavioral outcomes and labor productivity

While many of the world’s poor consume inadequate calories with low nutritional value, there has been little work on how this may shape their behaviors and productivity. Using lab-in-the-field and field experiments in the context of a floriculture plant in Ethiopia, this study investigates the effects of a nutrition support program on behavioral outcomes—stress, prosociality, cooperation, and attention—and productivity. We find that nutrition support relieves stress and decreases prosociality, exhibiting a pattern of hedonic adaptation over time. We do not find evidence for improvements in labor productivity.
