“…Policy experimentation in the states allows scholars to test whether a given policy mitigates or exacerbates income inequality. Previous studies have examined the effect of state-level welfare spending, unemployment and disability insurance, progressive tax rates, Earned Income Tax Credits (EITCs), the minimum wage, right to work, and levels of unionization on inequality (Barrilleaux and Davis 2003; Bucci 2018; Hatch and Rigby 2015; Hayes and Medina Vidal 2015; Kelly and Witko 2012; Kogan 2017). In their excellent work on state policy and inequality, Franko and Witko (2018) identify some states as leaders in adopting policies to mitigate inequality, such as Washington, New Mexico, Oregon, Michigan, and New York, each of which adopted higher minimum wages and more generous EITCs.…”
