  1. Notes: “Immig. component” refers to the immigrant component of labor supply and “National stock” refers to the labor supply among all Southern-born workers (including those living in the North). Except where noted, wages and labor supplies are measured using all Northern labor. Standard errors for the estimates of σ i , σ r , and σ x are clustered by education-experience group (or race-education-experience groups for models that pool both races); standard errors for σ e are heteroskedasticity-robust. All regressions are weighted by the number of observations used to construct the dependent variable
