a b s t r a c tThe paper examines the effects of five major socialization agents-namely parents, peers, traditional media, the Internet, and music industry-on emerging adults' attitudes and behavior toward music piracy in the form of unauthorized downloading. Based upon self-reported behavior, our study shows that these socialization agents exert differential effects on music piracy. Specifically, peers and the Internet exert direct impact on both attitudes and behavior. Parents and music industry, however, only have indirect impact on emerging adults' piracy behavior through shaping their attitudes. The research further shows that the effects of socialization agents differ across consumer segments. A factor mixture modeling technique is first applied to disentangle the behavioral heterogeneity, and more observable factors such as demographic, social, and psychological variables are then utilized to profile members in each segment. From a managerial perspective, this research provides new avenues for managers and policy makers to design targeted prevention programs to curtail music piracy.Published by Elsevier B.V.
