Additional Trial Information
We examine the role of information and incentives on household energy consumption. We partner with a local utility company to recruit and evaluate alternative ways to conserve energy. We use administrative data to evaluate behavioral changes in the short and long run of different treatments.
Castillo, Marco and Ragan Petrie. 2020. "Behavioral and Information Barriers to Energy Conservation: A Field Experiment in Alaska." AEA RCT Registry. May 26.
Volunteer households are randomly assigned to information and incentive treatments for energy usage. Administrative records on energy consumption are evaluated before and after the intervention.
Intervention Start Date
Intervention End Date
Primary Outcomes (end points)
energy consumption over time
Primary Outcomes (explanation)
Secondary Outcomes (end points)
Selection into treatments, study completion rates, information acquisition.
Secondary Outcomes (explanation)
Invitation to participate in the study is sent to the population of qualified households. Volunteers are randomly assigned to treatments including incentives and information on energy usage. Data on energy consumption is gathered and endline survey is conducted.
Experimental Design Details
Private randomization using office computer (random seed saved for replication).
Was the treatment clustered?
Sample size: planned number of clusters
Sample size: planned number of observations
Sample size (or number of clusters) by treatment arms
200+ information treatment, 200+ incentive treatment, 200+ control
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
14 percentage point difference between each treatment for binary variables (2-sided, power = 0.8). 16 percent change on consumption level without covariates (2-sided, power = 0.8).
