Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
I plan to have 5 active buyers and 5 active sellers. In the treatments with queues, I plan to have a further 8 participants (half buyers and half sellers).
Sample size (or number of clusters) by treatment arms
In total, the treatments will involve 2 x 10 + 2 x 18 = 56 participants.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
