Experimental Design
Experimental Design
We manipulate the level of anchors in a bargaining game.
Experimental Design Details
Not available
Randomization Method
Done by computer in the laboratory
Randomization Unit
Individual
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
About 135 groups of three participants
Sample size: planned number of observations
About 135, each cluster is one independent observation
Sample size (or number of clusters) by treatment arms
35 per treatment
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We did not perform a power calculation because It is hard to assess what the difference in the anchoring effect between treatments will be and the pilot does not provide sufficient information to be certain what size of effect we can identify. Even more so because there is uncertainty about the variance in anchors that will be chosen by retailers.
