Hilary Hoynes is an economist and Haas Distinguished Chair in Economic Disparities at the Richard and Rhoda Goldman School of Public Policy at the University of California at Berkeley.
[3] Her research has covered every major government anti-poverty program in the United States, including The Earned Income Tax Credit, Food Stamps, and Temporary Assistance for Needy Families, and has examined outcomes such as labor supply, employment, marriage, divorce, infant health, and education.
The authors do mention that not all treatment effects are statically significant; still they point to improvements in birth weights following the introduction of the Food Stamp Program.
Preschool programs have longer-lasting impacts for children who do not speak English at home, Hoynes describes the EITC as the "cornerstone of U.S anti-poverty policy".
Hoynes and Ankur J. Patel found that the 1993 expansion of the EITC increased employment for single mothers with less than a college degree by 6.1 percentage points.
