In most disability insurance programs beneficiaries lose some or all of their benefits if they earn above an earnings threshold. While intended to screen out applicants with high remaining working capacity, earnings limits can also distort the labor supply of beneficiaries. We use a reduction in the earnings limit in Hungary to evaluate this trade-off and examine screening and labor supply responses. We find that the policy changed selection into the program modestly but reduced labor supply on the intensive margin significantly. These findings suggest that the earnings threshold should be higher.
