Secondary Outcomes (explanation)
The secondary outcomes uses data from the same subjects from the end of session 1, where they are asked for their WTW right away, and for their WTW in session 3. Together with the same answers at the end of session 2, this can be used to estimate the degree of projection bias at the individual-level.
If the budget permits, I will ask these subjects to participate in the same experiment several months later, to measure measure how stable projection bias is for a given individual.
In addition to these primary goals focused on simple projection bias, I will ask several questions at the end of session 2 and session 3 to test whether subjects mispredict others' preferences; and whether they make mistakes in remembering their own choices based on how they currently feel about such past choices.
