No

Experiment Characteristics

Sample size: planned number of clusters
With 144 subjects, we will have 144 clusters in the first round, before subjects get feedback about others' choices.
144 / 3 = 48 clusters in later rounds to account for non-independence within fixed groups of three after the first round.
Sample size: planned number of observations
144 subjects, each making a choice for up to ten rounds. The number of rounds, and hence the number of observations, will be determined randomly since the design includes a continuation probability.
Sample size (or number of clusters) by treatment arms
144 subjects, split equally among the three continuation probabilities. We aim to run 12 sessions of 12 subjects. Depending on turnout, each session might have slightly more or slightly fewer subjects.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
