We rely on Huber's (1991) categorization of five knowledge acquisition types – experiential learning, vicarious learning, searching, grafting, and congenital learning – to organize our review and to guide our examination of the literature. We discuss convergent findings in terms of conceptual and empirical issues and set forth areas for future research.engrestrictedAccessarticle27114316500029845300001010.1016/j.jbusvent.2011.09.003Early internationalizationLearningKnowledgeHuber2-s2.0-81555202534
