移民对工资的影响很大程度上取决于技术相似的移民与本地人之间的替代弹性，以及高中辍学者与毕业生之间的替代弹性。本文重新审视了这些弹性的估计。美国的数据表明，同等技能的移民和当地人是完美的替代品。第二个弹性的值取决于如何控制对高中辍学者和毕业生产生不同影响的需求变化。在标准趋势假设下，这些群体是不完美的替代品，但即使是与这些假设的轻微偏差也可能导致对 CES 框架的彻底拒绝。
The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that equally skilled immigrants and natives are perfect substitutes. The value of the second elasticity depends on how one controls for changes in demand that have differentially affected high school dropouts and graduates. The groups are imperfect substitutes under standard trend assumptions, but even slight deviations from these assumptions can lead to an outright rejection of the CES framework.
