Guaranteed Income and Health Consortium

The Guaranteed Income (GI) and Health Consortium at Hopkins is focused on providing technical assistance and setting the landscape for Guaranteed Income and health, developing a conference grant together. In an era where disparities in health equity are brought to the forefront, we will be advancing efforts to extend the opportunity to attain the highest level of health. 

As part of the Guaranteed Income Consortium Initiative, our goals are:

  • Convene with health experts who are committed to addressing poverty as a fundamental cause of health. 
  • Evaluate and consult GI pilots across the US about how to incorporate health into their data collection, analyze, and report on those data.
  • Advance the scholarship and build the scientific evidence for GI’s impacts on health and health equity.

Paul Shafer

Paul Shafer, PhD

Boston University

Dr. Shafer's GI research focuses on the 2021 Child Tax Credit (CTC) expansion under the American Rescue Plan Act. His team found that its introduction in July 2021 decreased food insufficiency among households with children by 26% and later that its expiration at the end of 2021 gave back that progress, resulting in a corresponding 25% increase by July 2022.

Dr. Bouchelle is a pediatrician and health services researcher focused on reducing the negative impacts of poverty on the health and well-being of children and families. Dr. Bouchelle's prior work has examined the impact of the CTC on food insufficiency in lower-income households and explored interventions to address poverty-related social needs through the healthcare system.

Boston University School of Public Health

Dr. Ettinger de Cuba has worked on advocacy related to the EITC, CTC, and income-related issues for many years. She is a co-PI of a mixed methods study of the impact of the advance CTC on the health and well-being of families with young children, with a particular focus on families of color and immigrant families. This study also explored structural barriers to the advance CTC. In addition, Dr. Ettinger de Cuba has also co-authored two nationally representative studies on the CTC and food insufficiency (decrease in food insufficiency after the implementation of the advanced CTC and increase in food insufficiency after its expiration) and is currently developing several other GI-focused projects.  More on the project can be found at

Brooke E.E. Montgomery, PhD, MPH

University of Arkansas for Medical Sciences
Fay W. Boozman College of Public Health

"Our Stage 3 efficacy study aims to inform health policy by testing a novel intervention that directly reduces the racial income gap by providing a temporary guaranteed income (GI), which is intended to promote and protect Black men’s health through the influx of capital and subsequent increases in personal agency and social connections. We hypothesize that (1) providing GI of $500 per month for six months will result in increased healthcare utilization among chronically-ill, older and aging, low-income Black men; and (2) the effect of GI will depend on whether an individual has a recent history of incarceration, such that no incarceration history combined with GI will demonstrate the best study outcomes. Empirical research examining GI among older Black men and its capacity to overturn structural racism are lacking in the extant literature—much of the health disparities research intended to inform health and economic policy originated from limited perspectives of older and aging Black men—Dr. W.E.B. Du Bois said in The Souls of Black Folk that for Black people, “discouragement is an unwritten word”; this study draws on that inspiration as it ultimately seeks to fundamentally overturn the economic oppression and brutality that has defined the Black experience for generations."

Matthew sees GI as one part of a multipronged struggle toward justice and collective liberation. Unconditional cash is not a silver bullet, but it is a powerful, cross-sectoral tool that Matthew believes can be used within our current economic system to provide some relief for people living in poverty. GI can also promote community healing and power-building.
