Previous research in economics, social psychology, and sociology has producedcompelling evidence that social norms influence behavior. In this paper we applythe Krupka and Weber (2013) norm elicitation procedure and present U.S. andnon-U.S. born subjects with two scenarios for which tipping and punctualitynorms are known to vary across countries. We elicit shared beliefs by havingsubjects match appropriateness ratings of different actions (such as arrivinglate or on time) to another randomly selected participant from the sameuniversity or to a participant who is born in the same country. We also elicitpersonal beliefs without the matching task. We test whether the responses fromthe coordination task can be interpreted as social norms by comparing responsesfrom the coordination game with actual social norms (as identified usingindependent materials such as tipping guides for travelers). We compareresponses elicited with the matching tasks to those elicited without thematching task to test whether the coordination device itself is essential foridentifying social norms. We find that appropriateness ratings for differentactions vary with the reference group in the matching task. Further, the ratingsobtained from the matching task vary in a manner consistent with the actualsocial norms of that reference group. Thus, we find that shared beliefscorrespond more closely to externally validated social norms compared topersonal beliefs. Second, we highlight the importance that reference groups (forthe coordination task) can play.
