Experimental Design (Public)
|
Before
Participants will play 4 rounds of the trust game (Berg et. al. 1995).
The basic setup consists on two players (sender, receiver) that have an initial endowment of $X. The sender chooses what fraction of her endowment $Y she’ll send to the receiver. $Y is tripled on its way to the receiver, and he now decides how much of his $X+3Y to send back to the sender.
Pairs will be re-matched every round.
Before making each rounds' decision, players will receive a card with demographic information of their counterpart (gender, age, education level, neighborhood, and nationality).
Subjects will be assigned the same role they had in 2007.
Only the first round will be used for direct comparison with 2007 trust levels.
