Aid to Families with Dependent Children, or AFDC, was a U.S. means-tested cash assistance program for low-income families with children. It is economically important because it became a central case in debates about poverty relief, benefit design, and work incentives before being replaced by TANF in 1996.
Why Economists Studied AFDC
AFDC provided cash support to eligible families, but benefits often fell as earnings rose. That created an implicit marginal tax rate on work because additional labor income could reduce eligibility or shrink benefits.
A simplified way to write the budget constraint is:
[ Y_d = w h + B - t(wh) ]
where wh is labor income, B is the benefit, and t(wh) represents taxes plus benefit phase-out. If benefits are withdrawn quickly, the effective return to working more becomes smaller.
The Core Policy Trade-Off
AFDC illustrates a classic welfare-design problem:
- generous benefits can reduce hardship and improve child well-being
- steep benefit phase-outs can weaken work incentives at the margin
The question is not whether support should exist, but how to design support so it reduces poverty without creating unnecessarily high effective tax rates.
From AFDC To TANF
In 1996, AFDC was replaced by Temporary Assistance to Needy Families. TANF moved away from open-ended entitlement and toward block grants, time limits, and stronger work requirements. That shift reflected a policy judgment that the old structure placed too much weight on cash support relative to employment incentives and state flexibility.
