As markets become increasingly global, an understanding of the world's cultures is imperative. This special issue consists of nine articles devoted to increasing our understanding of culture. It follows the 11 th Cross-Cultural Research Conference, which was held in Puerto Rico in December 2005. An open invitation to conference participants and other interested researchers resulted in 56 submissions for the special issue. Articles chosen were subjected to several rounds of double-blind reviews and revisions. They cover a variety of topics including vacationing, managerial competency appraisal, horizontal and vertical individualism and collectivism, consumer services, cultural conditioning, electronic word-of-mouth, the global hip-hop culture, ethical attitudes, and impulse buying behavior.
