Summary statistic of experimental design.

Our study provides new evidence on the impact of positive emotions on voluntary contributions to public goods in a natural setting. Using a lab-in-field experiment, we induce positive incidental emotions randomly and analyze their effects on donations using a dictator game with multiple beneficiaries. Although we find no significant overall effect of positive incidental emotions on donation levels, our results show a significant shift in the allocation of donations towards the host charity. These findings shed light on the complex role of emotions in donation behavior and can provide valuable insights for organizations seeking to increase charitable giving.
