REGRESSION
The following regression estimates spillover effects by including the two ‘embedded placebo’ dummy variables: HealthPlacebo and CashPlacebo. In our pre-registration, we hypothesized that vaccination rates of individuals receiving the placebo treatment in villages assigned to a cash treatment would be depressed. In this specification, we are testing whether the 25% of placebo individuals in villages assigned the health message or cash treatments have vaccination rates that are different than those for individuals in the villages assigned to the placebo treatment. Our expectation is that the overall average vaccination rates will be depressed for the 25% in the cash-treated villages, hence the expectation that We also restrict the regression analysis to the placebo participants and estimate the following equation:Again, our pre-registered hypothesis was that
