Experiment Characteristics

Sample size: planned number of clusters
As many clusters as individuals. See below for the number of individuals.
Sample size: planned number of observations
4,159 participants will be contacted. We expect that around 3,000 of them will complete the survey. The sample of 4,159 contacted participants consists in the individuals who took the first wave of our survey. This earlier data collect effort was described in AEARCTR-0015302.
Sample size (or number of clusters) by treatment arms
We plan to randomly split out sample into three groups of equal size. We expect around 1,000 respondents per group.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
