Big men and the conversational marketplace of Tanna (Vanuatu)

“Big men” in different parts of Melanesia achieve political status by various means. However, all big men possess a reputation—a “big name.” Reputations grow or decline as people talk. Big men acquire renown by meeting the costs of the “conversational marketplace,” to use Randall Collins’ term. Some of these costs are systemic, given by the local mode of communication; others are discursive, related to cultural rules for producing authentic talk. This paper describes the conversational costs of acquiring renown on Tanna, Vanuatu. It traces how Nampas, who emerged as a leader of the John Frum movement, made his name by investing in the island's conversational marketplace.
