We collect 1,030 previously estimated wage effects and 432 employment effects of immigration, and we document that the mean and median effects on the relative wage are negative and significantly different from the small positive mean and median effects on the average wage. The pattern is reversed for employment effects where the magnitudes are also smaller. Combining the effect sizes with measures of labor market institutions, we find that institutions might shield native workers from relative wage consequences but reduce the average wage effect of immigration. We do not detect a significant and robust association for the employment effects.

劳动力市场机构在移民对工资和就业的影响中的作用*

我们收集了 1,030 个先前估计的工资效应和 432 个移民的就业效应，我们记录了对相对工资的均值和中值影响是负的，并且与对平均工资的较小的正均值和中值影响显着不同。对于幅度也较小的就业影响，这种模式是相反的。将效应大小与劳动力市场制度的衡量相结合，我们发现制度可能会保护本土工人免受相对工资后果的影响，但会降低移民的平均工资效应。我们没有发现就业影响存在显着且稳健的关联。
