    Public good provision, in-group cooperation and out-group descriptive norms: A lab experiment
    (2021)

    We use a public good experiment to study how in-group cooperation is affected by payoff-irrelevant information about cooperation in other groups (i.e., descriptive out-group feedback). We find that positive out-group feedback, indicating above-average cooperation, deters low in-group contributors from increasing their contribution towards the in-group average. By contrast, negative out-group feedback, which informs participants about below-average cooperation, deters high in-group contributors from decreasing their contribution towards the in-group average. These two effects work together to dampen contribution patterns associated with conditional cooperation. Further, we show that the effects are stronger for individual-level feedback (comparing individual contributions with the out-group average) than for group-level feedback (comparing total contributions by in-group members with that of other groups). Interestingly, when allowed to avoid out-group feedback information, the propensity to consult the feedback is similar for high and low in-group contributors, suggesting that information acquisition is not always self-serving.

    When within- and outgroup norms conflict: A public good experiment with strategic ignorance of social norms
    (2019)

    Social norm feedback, i.e. informing people about the behavior of others, has been shown to influence prosocial behavior in many domains, including tax compliance and energy conservation. We introduce social norm feedback in a public good setting and study the interplay between payoff-relevant within-group norms and payoff-irrelevant outgroup norms. We show that conflict between within- and outgroup norms dampens within-group conditional cooperation. Further, participants strategically ignore outgroup norms when these go against self-interest, instead consulting norm information that allows them reducing their contributions. On aggregate, such information acquisition/avoidance strategy favors exposition to norms that hastens the breakdown of cooperation. Finally, norm avoidance is higher when feedback is based on individual rather than group-level comparisons, which is consistent with a self-image cost associated with social norm feedback.
