Does immigration raise or lower wages for less-educated native workers?
Core argument: The 2000–2019 immigrant inflow is estimated to have raised wages of natives with a high school degree or less by 1.7%–2.6%, attributed to immigrants' concentration among the college-educated and complementarity between college- and non-college-educated workers.
Three findings emerge from columns (1) to (4) of Table 9. First, due to the relative concentration of new immigrants among college-educated and the complementarity between college- and non-college-educated, the immigrant inflow of 2000-2019 helped the wage growth of less-educated natives (those with high school degree or less) by between 1.7% and 2.6%. This represents a significant boost in real wages, especially considering that the real wage growth of this group during the 2000-2019 period was actually negative, between -5% to -6%. Second, in spite of the large inflow of college-educated immigrants, the complementarity between immigrants and natives, attenuated or reversed most of the competition effect for the groups with some college education or a college degree. As a result, they also experienced between no and small effects (between -0.5% and +0.7%). Third, the average effect on wages of natives was small, overall positive (+0.5% to +0.8%) and not statistically significant.
