Experimental Design

Experimental Design
This pre-registration describes a laboratory experiment to be conducted at the University of Zurich to study the present bias phenomenon in inter-temporal decision making. We describe the experimental design, the variables of interest, the hypotheses, and sample size.
Experimental Design Details
Not available
Randomization Method
Randomization done by a computer.
Randomization Unit
All subjects will face the same experiment but stimuli will be presented in four different pseudo-random sequences (randomly assigned to subjects).
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
We will run sessions with 36 invited subjects each until we have 128 or more (nonexcluded) subjects.
Sample size: planned number of observations
We will run sessions with 36 invited subjects each until we have 128 or more (nonexcluded) subjects.
Sample size (or number of clusters) by treatment arms
We will run sessions with 36 invited subjects each until we have 128 or more (nonexcluded) subjects.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
