Experimental Design

Experimental Design
Subjects value lotteries of outcomes at different dates with dated sure outcomes.
Experimental Design Details
See the "Experimental Design" document uploaded to the Docs & Materials section.
Randomization Method
The order of four within-subject treatments is randomized by a computer.
Randomization Unit
The randomization of the order of the four within-subject treatments is at the level of experimental sessions.
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
10 experimental sessions.
Sample size: planned number of observations
200 undergraduate students from Nankai University
Sample size (or number of clusters) by treatment arms
Since the main design involves within-subject treatments, all 200 subjects in the sample make choices in all four treatments.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
