Using an online sample of more than 1,000 participants, we observe behavior in a one-shot sequential voluntary contribution mechanism game where leaders and followers are induced to be either happy or angry. Our findings show that angry leaders contribute less than happy leaders. The same effect is observed when considering followers\u2019 behavior. A follow-up study uses the strategy method where the leader's actual contribution is not revealed to followers and shows that angry followers behave no differently from happy followers. This suggests that the effect of induced emotions on followers\u2019 behavior operates primarily through the leader's behavior, highlighting the importance of leader emotions in shaping team outcomes. More broadly, our findings highlight the role of emotions as a causal force, suggesting that negative changes in well-being can bring about adverse effects on team cooperation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"630\" src=\"https:\/\/www.iseg.ulisboa.pt\/wp-content\/uploads\/ISEG_Research_Seminars26_MetaTag-2.png\" alt=\"\" class=\"wp-image-67937\" srcset=\"https:\/\/www.iseg.ulisboa.pt\/wp-content\/uploads\/ISEG_Research_Seminars26_MetaTag-2.png 1200w, https:\/\/www.iseg.ulisboa.pt\/wp-content\/uploads\/ISEG_Research_Seminars26_MetaTag-2-300x158.png 300w, https:\/\/www.iseg.ulisboa.pt\/wp-content\/uploads\/ISEG_Research_Seminars26_MetaTag-2-18x9.png 18w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"No dia\u00a029 de maio, entre as 13h00 e as 14h00, tem lugar uma sess\u00e3o dos ISEG Research Seminars.
