Contexto
What changed: Participation in the HIMO public works program, which provides labor-intensive employment and constructs community infrastructure. Comparison: Households not participating in HIMO, identified via instrumental variable estimation. Limits: Relies on cross-sectional survey data (MICS6 2018) and the instrument (meeting with a social agent) has a first-stage F-statistic of 9.10, indicating potential weak-instrument concerns.
