Abstract
How do past failures shape future decisions? This article experimentally investigates the dynamic role of negative emotions on investment behaviour. To do this, we first augment traditional reference-dependent models to integrate the effect of past emotions on utility. Emotions stemming from past failures linger and affect utility negatively, but success brings emotional relief. Using these portable principles we derive testable implications without imposing functional form assumptions on the reference-dependent utility function.

Primary Outcomes

Primary Outcomes (end points)
Within the same decision task: the difference between subjects' choices of effort levels when they are frustrated and when they are not.

Between different tasks: the difference in the difference above.

Experimental Design

Experimental Design
We employ a within-subject design. Subjects first face six different decision tasks. In each task, there is a list of gambles. Subjects need to exert effort to acquire the gamble. In general, the more effort they exert, the higher the expected value would be from the gamble. The tasks differ in whether the effort increases the chance of winning or the return of winning. Subjects choose one gamble from each decision task.

Then, subjects do a short filler task (be distracted), after which they receive either a high payment or a low payment. We consider the subjects who receive a low payment to be frustrated.

Last, subjects are presented with the same six decision tasks again. They can make choices the same as or different from their previous choices, depending on themselves. In total, they choose 12 gambles. We draw one gamble for them to work on.

Randomization Method
We do within-subject design and only have one treatment. Hence, there is no need to randomize subjects into different treatments. However, we do have some lottery outcomes during the study. These randomizations are done by the Z-tree computer program.
Randomization Unit
Individual.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
Depending on how emotion affects people's utility (whether he is frustration-aversion, and whether he is prudent), subjects can be divided into 4 types. For each type, the amount of frustrated subjects is 28. On average half of the subjects will be frustrated. Therefore, for each type, the expected sample size is 56.
Sample size: planned number of observations
For all 4 types to have enough power, we need 56*4=224 observations.
Sample size (or number of clusters) by treatment arms
For each type, the expected sample size is 56. For all 4 types to have enough power, we need 56*4=224 observations.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
For each type, with 56 samples, effect size 0.5, and significant level 0.05, we can achieve power 0.805. Notice that we do now know ex-ante how many percentages of subjects will fall in each type. Therefore, the above power can be achieved only after we categorize people into their corresponding types.
