Table 1:
Tobit regression on contribution decisions with random effects at subject level (5460 decisions, of which 2376 censored, by 182 subjects).

*Significant at .05-level; ** Significant at .01-level (2-sided).
Table 2:
Tobit regression on contribution decisions in the punishment conditions with random effects at subject level (1638 decisions, of which 345 censored, by 182 subjects).

*Significant at .05-level; ** Significant at .01-level (2-sided).
Table 3:
Tobit regression on contribution decisions in the reward conditions with random effects at subject level (1638 decisions, of which 981 censored, by 182 subjects).

*Significant at .05-level; ** Significant at .01-level (2-sided).
