The ability of minimum-wage policies in the United States to aid lower-income families depends on how they affect wage gains, potential job losses, and other sources of family income, including public assistance. In contrast to a large body of research on the effects of minimum wages on employment,1 there are relatively fewer studies that empirically estimate the impact of minimum wage policies on family incomes.
Overall, I find robust evidence that higher minimum wages lead to increases in incomes among families at the bottom of the income distribution and that these wages reduce the poverty rate. A 10 percent increase in the minimum wage reduces the nonelderly poverty rate by about 5 percent. At the same time, I find evidence for some substitution of government transfers with earnings, as evidenced by the somewhat smaller income increases after accounting for tax credits such as the Earned Income Tax Credit and noncash transfers such as the Supplemental Nutrition Assistance Program. The overall increase in post-tax income is about 70 percent as large as the increase in pretax income.
