To match the survey studies and provide a better grip on the mechanisms and causal underpinnings of sustainable cooperation, several types of experiments will be performed. First, various groups from the SCOOP consortium will run experiments within their own disciplinary context, using existing infrastructure, targeting the sustainability of cooperation. Second, linked to and integrated with the surveys, targeted experiments will be conducted on specific cooperation-related issues inside the panels, i.e., we invite samples of respondents to experimental settings. An important aim of these experiments is to control, complement, and validate experimental studies done more locally in the SCOOP consortium. Third, experimental designs will be explicitly included in the panels. With the application of factorial designs, experiments may be instigated in a random and non-selective population of respondents.
