Notes: Dependent variables are the child's weight in kilograms (columns 1, 4 and 7), weight-for-age z score (columns 2, 5 and 8), and weight-for-age malnutrition status (columns 3, 6 and 9) defined as an indicator equal to 1 if weight-for-age z score <2. Panel A uses outcomes at Endline I in April 2015, for which payouts were made in May 2015. Panel B uses outcomes at Endline II in July 2015, several months after the contest ended. "Proportional" is an indicator equal to 1 for children at centers randomized into proportional rewards, relative to the omitted control which is a winner-take-all prize. Child and mother-level controls include age and sex of the child, the age of the mother, the total number of children in the home, the total household income, and if the mother cannot read and write. Worker-level controls include the Anganwadi worker's age and if she is college-educated. Heteroscedasticity-consistent standard errors accounting for clustering at the Anganwadi center level in parentheses. *Significant at 10%, **Significant at 5%, *** Significant at 1%.
