Experimental Design

Experimental Design
Randomization was at the neighborhood level. Randomization is stratified by district and vote share for the national coalition in the previous election. There are two treatment arms and one control group. Due to the small number of treated neighborhoods, we only have statistical power to detect major effects. As we may lack the power to test smaller effects, this experiment could serve as a pilot for future studies.

Experiment Characteristics

Sample size: planned number of clusters
89 neighborhoods
Sample size: planned number of observations
All the ballot boxes contained in 89 neighborhoods (we do not have the 2023 electoral data yet and so do not know the number of ballot box in each neighborhood)
Sample size (or number of clusters) by treatment arms
22 neighborhoods in each of the two campaign treatment groups and 45 in the control group.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
