Official title

An Experimental Investigation Into the Impact of Socioeconomic Context on Biological Markers of Aging, Health and Mortality

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
