A proposal to raise the federal minimum wage to $15 by 2024 would increase the relative minimum wage – the ratio to the national median wage– to about .68. In Alabama and Mississippi, our two lowest-wage states, the relative minimum wage would rise to .77 and .85, respectively. Yet research on state-level minimum wage policies does not extend beyond $10; the highest studied state-level relative minimum wage is .59. To close this gap we study minimum wage effects in counties and PUMAs where relative minimum wage ratios already reach as high as .82. Using ACS data since 2005 and 51 events, we sort counties and PUMAs according to their relative minimum wages and bites. We report average results for all the events in our sample, and separately for those with lower and higher impacts. We find positive wage effects but do not detect adverse effects on employment, weekly hours or annual weeks worked. We do not find negative employment effects among women, blacks and/or Hispanics. We do find substantial declines in household and child poverty.
