What is a welfare cliff, and how can policy design prevent cliffs in means-tested programs?

• A. A welfare cliff occurs when benefits rise sharply with small increases in earnings.
• B. A welfare cliff occurs when benefits sharply drop with small increases in earnings; prevention includes smoother phase-outs, increased earnings disregards, and EITC expansion.
• C. A welfare cliff is a theoretical concept with no real-world impact.
• D. Welfare cliffs apply only to unemployment benefits.

Answer: (B)

A welfare cliff happens when small increases in earnings lead to large drops in benefits, so the total resources a household has can fall or barely rise as work effort increases. This creates a strong work disincentive: you might earn a little more, but you lose more in benefits than you gain in pay, making work harder to justify financially.

Policy design can prevent these cliffs by smoothing the transition from relying on benefits to earning wages. That means reducing abrupt cutoffs with gradual phase-outs as earnings rise, increasing the amount of earnings that are disregarded when benefits are calculated so a larger slice of work income is kept, and expanding the Earned Income Tax Credit to support a more gradual or higher benefit level across a wider range of earnings. Together, these tools lower the effective marginal tax rate on earnings, so small increases in work income actually translate into real gains rather than triggering steep benefit losses.

Cliffs aren’t limited to unemployment benefits; they can occur in many means-tested programs. By designing benefits to phase out more gradually and by boosting earnings disregards and the EITC, policy can encourage work and upward mobility rather than discouraging it.
