Primary Outcomes
Primary Outcomes (end points)
The primary outcome variable for this experiment is external margin. When treated, are subjects less likely to take the experimenter's up on an employment offer? The second outcome for this experiment is the internal margin. Given that a worker chooses to continue, how well do they complete the task they are assigned. We will measure both attempts and accuracy.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
We will employ text analysis on subject's journals.
