Experimental Design
The experiment will be conducted on the online survey platform Qualtrics. Participants will be recruited on Prolific. They will receive a fixed show-up fee and be given an experiment stock as a bonus. The return for stock is determined as follows: A computer will randomly draw one card from a set of 4 cards, which includes 1 red card, 1 white card, 1 black card, and 1 blue card. Depending on which card is drawn, the stock will pay a certain amount of money. For example, suppose the following stock (namely, Stock A) is given to the participant:
• If the red card is drawn, the participant will receive a return of $15.
• If the white card is drawn, the participant will receive a return of $2.
• If the black card is drawn, the participant will receive a return of $0.
• If the blue card is drawn, the participant will receive a return of $8.
The participant can keep Stock A, i.e., choose the default, or she can trade the stock for another stock (namely, Stock B). The experiment follows a mixed design including a between-subject factor (Coin vs. No Coin) and a within-subject factor (Stock A is the default vs. Stock B is the default). When a participant chooses to keep Stock A when Stock A is the default but chooses to keep Stock B when Stock B is the default, we consider this participant commits default bias facing Stock A and B.
At the end of the experiment, we select 5 choice tasks they did, and ask them to recall their decisions. Each decision that was successfully recalled would receive US$0.2.
The following information will also be collected from the participants:
1. Response time
2. Demographic information (gender, age, education, employment, and religion)
