Primary Outcomes
Primary Outcomes (end points)
Subjects' valuations of different lotteries.
Primary Outcomes (explanation)

Secondary Outcomes (explanation)
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)
