| Abstract: | This paper examines how beliefs and preferences drive identity-conforming consumption or investments. We introduce a theory that explains how identity distorts individuals’ beliefs about potential outcomes and imposes psychic costs on benefiting from identity-incongruent sources. We substantiate our theoretical foundation through two lab-infield experiments on soccer betting in Kenya and the UK, where participants either had established affiliations with the teams involved or assumed a neutral stance. The results indicate that soccer fans have overoptimistic beliefs about match outcomes that align with their identity and bet significantly higher amounts on those than on outcomes of comparable games where they are neutral. After accounting for individuals’ beliefs and risk preferences, our structural estimates reveal that participants undervalue gains from identity-incongruent assets by 9% to 27%. Our counterfactual simulations imply that identity-specific beliefs account for 30% to 44% of the investment differences between neutral observers and supporters, with the remainder being due to identity preferences. |

| Abstract: | L'Observatoire du Sport Français de l'Université de Poitiers a été créé 2014 afin d'objectiver la prise de décisions des politiques sportives à partir de l'exploitation de données qui apparaissaient sous estimées. Par exemple, il s'agit de croiser des données du sport fédéral (ex. : nombre de licences, de clubs, de sportifs de haut niveau) et socio-économiques (ex. : revenus médians par territoire) pour mettent mettre en exergue des éléments d'analyse. Cette sous-exploitation provient souvent d'un manque d'un manque de connaissance de l'existant mais aussi d'un déficit de moyens et/ou d'expertise pour faire émerger ces données, être en mesure de les faire comprendre et de les analyser. L'ambition de cet Observatoire est ainsi d'accompagner à la mise en place des politiques sportives (formalisation, évaluation) à travers l'analyse des dynamiques territoriales et fédérales. La mobilisation d'outils de « datavisualisation » rend possible l'émergence d'un diagnostic partagé entre les différents acteurs du sport français, une étape nécessaire avant d'envisager de faire évoluer les orientations territoriales et/ou fédérales |

| Abstract: | Organizations increasingly rely on teams to solve complex problems. The ability of teams to work well together is critical to their success. I experimentally test whether team performance is affected by whether team members like each other. I find that teams in which partners like each other do not outperform teams in which partners dislike each other. However, teams in which one partner likes the other more than the other perform best. The performance differences result directly from changes in collaborative behavior when learning the team partner's interpersonal preferences, not indirectly from interacting with different individuals. Participants do not anticipate this pattern and expect to be most successful in a team where partners like each other. This provides insights into how teams should be optimally composed, when self-selection may be detrimental to performance, and what information about others' interpersonal preferences should be revealed. |
