Midlife mortality has risen steadily in the U.S. since the 1990s for non-Hispanic whites without a bachelor’s degree, and since 2013 for Hispanics and African-Americans who lack a bachelor’s degree. These increases largely reflect increased mortality from alcohol poisoning, drug overdose and suicide. We investigate whether these “deaths of despair” trends have been mitigated by two key policies aimed at raising incomes for low wage workers: the minimum wage and the earned income tax credit (EITC). To do so, we leverage state variation in policies over time to estimate difference-in-differences models of drug overdose deaths and suicides, using data on cause-specific mortality rates from 1999-2015. Our causal models find no significant effects of the minimum wage and EITC on drug-related mortality. However, higher minimum wages and EITCs significantly reduce non-drug suicides. A 10 percent increase in the minimum wage reduces non-drug suicides among adults with high school or less by 3.6 percent; a 10 percent increase in the EITC reduces suicides among this group by 5.5 percent. Our estimated models do not find significant effects for a college-educated placebo sample. Event-study models confirm parallel pre-trends, further supporting the validity of our causal research design. Our estimates suggest that increasing both the minimum wage and the EITC by 10 percent would likely prevent a combined total of around 1230 suicides each year.
