Table 2.
A comparison of the different behavioural rules, plus one combining them all together, across three different information treatments. (PBL, payoff-based learning (own success); PSL, pro-social learning (own success and others' success); CC, conditional cooperation (own success and others' actions). All, a combination of all the components from the three rules (own success, others' success, and others' actions). The parameters in the first three rows estimate the effects of unit changes in the predictor variables that act as components in the three learning rules; positive (negative) parameter estimators support (contradict) the respective hypothesis.)
