Relative Pay and Labor Supply
通过实验室实验研究相对工资对劳动力供给的影响，发现高相对工资增加供给、低相对工资减少供给，但若给出低工资的充分理由则差异消失。
We examine the impact of relative wages on labor supply in a laboratory experiment. We test the hypothesis that, ceteris paribus, making a given wage high (low) relative to other wage levels will lead to an increase (decrease) in labor supply. We find that labor supply does respond significantly to relative pay, and in the expected direction. However, when a strong enough reason for the relative low pay is given, this difference disappears.
