The Culture of Overconfidence

Abstract
Perceptions of overconfidence can exacerbate the tendency of reputationally concerned leaders to continue bad projects. Reputation concerns alone induce a bias toward inefficient continuation in a leader receiving information privately. When she is overconfident—or holds a more favorable prior than observers—this tendency is aggravated. This remains true even when she is not really overconfident, but merely perceived to be so. Higher-order beliefs regarding overconfidence induce inefficient equilibrium selection even when there is "almost common knowledge" that the leader is not overconfident. This provides a novel perspective on how culture selects among equilibria: via higher-order beliefs.Citation
