We experimentally study behavior in a simple voting game where players have private information about their preferences. With random matching, subjects overwhelmingly follow the dominant strategy to exaggerate their preferences, which leads to inefficiency. Applying a linking mechanism suggested by Jackson and Sonnenschein (2005) captures nearly all achievable efficiency gains. In the absence of that mechanism, repeated interaction leads to significant gains in truthful representation and efficiency only if players can choose their partners.
