摘要：I estimate the long-run income effect of welfare transfers on individual labor supply. Using Italian administrative data on the universe of survivor insurance recipients, I implement a regression discontinuity design around a change in survivor insurance generosity based on the spouse's death date. I find that survivors fully offset the benefit loss with increases in earnings. Labor force participation and program substitution are the main margins of adjustment. I consider potential explanations for the large income effect. Evidence suggests that the value of additional income in the widowhood state is large, driving large participation responses to survivor benefit cuts.
