Notes: Column 1: COVID-19 Knowledge Overall test score, the share of correct answers to 40 knowledge questions asked at endline that were also randomly selected for the respondent to answer at baseline. Column 2: Teaching-Eligible test score, the share of correct answers to 20 knowledge questions asked at baseline and hence eligible for all treatments. Column 3: Teaching-Ineligible test score, the share of correct answers to 20 knowledge questions NOT asked at baseline and hence NOT eligible for the Teaching intervention. Column 4: Newly-asked test score, the share of correct answers to the 20 or fewer endline knowledge questions that were NOT randomly asked of the respondent at either pre-baseline or baseline. $\lambda$ is the complementarity parameter (see Section 2). $‘‘\widehat{\lambda }’’$ is coefficient on “Incentive plus Teaching” (“Joint”) minus sum of coefficients on “Incentive” and “Teaching”. All regressions include community fixed effects and controls for pre-treatment (pre-baseline and baseline) test scores. Robust standard errors in parentheses. Significance levels in Columns 1 and 2 adjusted for multiple hypothesis testing across the three coefficients estimated (on Incentive, Teaching, and Joint treatments); p-values adjusted for multiple hypothesis testing in square brackets. *** p<0.01, ** p<0.05, * p<0.1.
