Experimental Design Details
Experiment 1 investigates the effect of current consumption on the demand for information about a potentially negative outcome. The information is a coin flip result as to whether the subject will be shocked at the end of the experiment (coin flipped heads) or not (coin flipped tails). Subjects are presented with a slice of bread and an ice-cream platter sequentially. With each food item before them, subjects are asked to choose the timing to know the coin flip result.

Experiment2 investigates the effect of aversive salient information on consumption. Subjects are randomly assigned to the control group with no information or the treatment group with information. The procedures of these two groups are identical, except that the information group gets a clue about the possibility of future shocks. We then wish to observe how this salient information affects the demand for full information, ice cream, distractors, and a shock block.

Please see pre-analysis plan for details.
Randomization Method
Whether the subject will be assigned to treatment group will be decided by a randomizer generated by Qualtrics prior to the commencement of each session.
Randomization Unit
Randomization will be carried out at individual level
Was the treatment clustered?
