Before
Participants take part in five sequences of a public goods game with dynamic contributions. At the beginning of each sequence, participants are divided into groups of four (random rematching across sequences), and each group member is given an endowment of 50 tokens. Each sequence consists of 10 rounds where, in each round, group members can decide how much of their remaining endowment to contribute to the Group Account. Any unassigned tokens at the end of the 10th round will remain in the members' Private Accounts. Group members receive their payoffs from the Group and Private Accounts only at the end of the 10th round.
Payoffs follow the standard VCM experiment: For every token remaining in a group member's Private Account, that member receives 1 token. For every token there is in the Group Account, each group member receives 0.4 tokens.
The main treatments vary on the information that group members receive at the end of each round of the sequence, with feedback being either time-based or milestone-based. Where feedback is milestone-based, we will also vary the intervals of the milestones.

After
[Study has been withdrawn as we decided to implement the experiment face-to-face instead of online, given the easing of COVID-19 restrictions in Australia.]
