We conducted continuous-time Common Pool Resource (CPR) experiments where resource users were allowed to (1) harvest from a dynamically varying resource (mimicking a fishery) and (2) change their extraction behavior in real-time under different treatments namely, communication and no communication. The experiments were conducted at the Leibniz Centre for Tropical Marine Research in Bremen, Germany in August 2015 and February 2016 with a total of 70 participants. This data is the resource levels and efforts (extraction levels) of the participants for the different treatments.
