Paycheck Plus (PP) is a randomized controlled experiment (RCT) that explores the health and longevity effects associated with increasing the Earned Income Tax Credit (EITC). EITC is a national program that provides tax credits to low-income, disproportionately minority workers who file taxes. EITC is politically popular, having received bipartisan support. The EITC, along with state supplemental programs, have 7 million American families out of poverty. The investigators' preliminary data analyses show that the EITC has had large population health impacts, reversing declines in self rated health and survival among the poorest Americans.

Poverty disproportionately impacts minority and rural populations and is very strongly correlated with poor health over the life cycle, and has been hypothesized to lead to a shorter, less healthy aging process. Poverty is associated with a greater burden of disease than smoking and obesity combined and accounts for the bulk of health disparities by race. It is widely believed that an antipoverty policy, such as Earned Income Tax Credit (EITC), could improve healthy aging among working-age low-income adults over the life cycle. It does so by increasing material hardship and psychological stress, two risk factors that are strongly correlated with biological markers of premature aging (e.g., shorter telomeres, higher cholesterol levels, and higher blood pressure).
