Experiment Characteristics

Sample size: planned number of clusters
Stratified randomisation, no clustering.
Sample size: planned number of observations
Analysis of face-to-face intervention: maximum 1,440 firms using survey data (720 firms in treatment group), and maximum 1600 firms using administrative data (800 firms in treatment group) Analysis of SMS interventions: maximum 43,330 firms using administrative data
Sample size (or number of clusters) by treatment arms
Analysis of face-to-face intervention: maximum 1,440 firms using survey data (720 firms in treatment group), and maximum 1600 firms using administrative data (800 firms in treatment group)
Analysis of SMS interventions: maximum 43,330 firms using administrative data (14,444 firms assigned to receive SMS with positive framing treatment, 14,443 firms assigned to receive loss aversion and risk perception framing)
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Assuming power of 80% and alpha as 5%, the minimum detectable effect sizes are the following: • Impact of face-to-face intervention on outcomes based on survey: 0.15 SD. • Impact of face-to-face intervention on outcomes based on administrative data: 0.14 SD. s.d. • Impact of one of the SMS interventions on outcomes based on administrative data: 0.03SD
