Do large minimum wage increases reduce employment while small ones do not?
Core argument: Four years after enactment of the first increase, large minimum wage increases are estimated to reduce employment by roughly 5pp among individuals aged 16–25 without a completed high school education and about 3pp among all individuals aged 16–21.
Figure 4 reports our imputation difference-in-differences estimates for the effects of small and large minimum wage changes on employment among individuals aged 16–21 and among individuals aged 16–25 with less than a completed high school education. The samples are from the ACS [American Community Survey]. [The data span 2011-2019]. We compare estimates for large versus small increases. The estimates to the left of the vertical dashed lines reveal no concerning evidence of divergent preexisting trends. We find null effects for the states that enacted small minimum wage increases and negative effects for states with large minimum wage increases. By 4 years after the enactment of the first increase, the estimate has approached −5pp for individuals aged 16–25 with less than a completed high school education, and −3pp for the sample of all individuals aged 16–21. [Editor's note: The authors note that Section VIII of the paper, which contains the Figure 4 imputation DiD estimates, “presents estimates from a modern difference-in-differences estimator that falls outside of our pre-analysis plan.” The results are somewhat larger than those reported in the Abstract.]
