Why are there cross-national differences in response to comparative advertising?: some mediators

This study conducted a lab experiment in the US and South Korea to test cross-national differences in response to comparative versus non-comparative Facebook advertising messages. Consistent with prior research, this study found that comparative ads resulted in more positive attitudinal responses among Americans, whereas non-comparative ads resulted in more positive attitudinal responses among Koreans. Results of multiple mediation tests showed that Americans showed more positive responses to a comparative ad message because the message was perceived to be more assertive than a non-comparative ad message, whereas Koreans showed more negative responses to a comparative ad message because the message was perceived to be less considerate than a comparative ad message. This study has important theoretical implications by testing multiple mediators for comparative ad effects; and also has practical implications for cultural adaptation marketing strategies.
