Julie L. Hotchkiss, PhD, Research Economist and Senior Advisor at the Federal Reserve Bank of Atlanta, Myriam Quispe-Agnoli, PhD, Visiting Associate Professor of Economics at Mercer University, and Fernando Rios-Avila, PhD, Research Scholar at the Levy Economics Institute of Bard College, in a Mar. 7, 2015 article, "The Wage Impact of Undocumented Workers: Evidence from Administrative Data," available in the Southern Economic Journal, stated:

“[R]ising shares of undocumented workers results in higher earnings for documented workers, but by a small amount. A one percentage point increase in the share of undocumented workers in a documented worker’s county/industry results in an average wage boost of 0.44%. Within the firm, a one percentage point increase in the percent of undocumented workers employed by the firm boosts wages by 0.09% (0.11, 0.12, and 0.04 in low, medium, and high skill firms, respectively).”
