Wage Increases and the Dynamics of Reciprocity
通过真实努力实验，研究了工资发放时间对工人绩效的影响，发现未知的递增工资方案能提升约15%的绩效，且工人对工资变化的互惠反应可用适应性参考标准模型解释。
We investigate how workers' performance is affected by the timing of wages in a real-effort experiment. In all treatments, agents earn the same wage sum, but wage increases are distributed differently over time. We find that agents work harder under increasing wage profiles if they do not know these profiles in advance. A profile that continuously increases wages by small amounts raises performance by about 15% relative to a constant wage. The effort reactions can be organized by a model in which agents reciprocally respond to wage impulses, comparing wages to an adaptive reference standard determined by the previous wage.
