When the rich contribute more in public good dilemmas: The role of provision point level

The present research examined the effects of endowment size, provision point level and the opportunity to voice one's opinion on contributions in asymmetric public good dilemmas. Results from a first experiment showed that group members endowed with more resources contributed more when the required threshold for obtaining a public good was high rather than low. Rich participants who reported that their personal contribution was more critical for success contributed more. However, most groups failed to surpass the high provision point threshold level. Results from a second experiment reveal that rich participants given voice, contributed more than rich participants not given a voice. Voice contributed to greater feelings of inclusiveness, higher contributions and increased the likelihood that the group surpassed the high provision point level.
