Income Targeting and Farm Labor Supply
利用美国全国农业工人调查数据，通过简化形式和结构模型检验计件工资制下农业工人是否存在收入目标行为，发现即使提高计件工资率也可能无法缓解农业劳动力短缺。
There is considerable anecdotal evidence that farm workers who are paid by piece rate tend to “income target,” or work only until they achieve a certain amount of daily income, and then stop work. We estimate reduced‐form and structural models derived from the reference‐dependent preference model of Koszegi and Rabin (2006) to test the income‐targeting hypothesis using data from the National Agricultural Workers Survey (NAWS). We find evidence that supports the income‐targeting hypothesis, in both the reduced‐form and structural econometric models. Our findings suggest that even higher piece rates may not help the widely reported shortage of agricultural labor on the intensive margin as labor‐supply curves can be backward bending.
