Abstract
This study examines whether antenatal care (ANC) practiced in rural Nigeria improves maternal and child health behaviors and outcomes. We randomize a cash incentive for one ANC visit and information about ANC at the village level. We examine the impacts of these one-shot interventions in the sequence of prenatal, intrapartum, and postnatal periods, over two years after birth. The study covers 1032 pregnant women in 100 villages.

Experimental Design

Experimental Design
Our experiment has four treatment arms: 1) incentive, 2) information, 3) combined, and 4) control. In the incentive group, if women make one ANC visit within a month, they receive 400 naira (US$2.7). In the information group, women are given general information about ANC: recommended visits, its purpose and benefits, and risks of not receiving it. The combined treatment group received both interventions. The control group received no interventions.
