Why a Group Needs a Leader: Decision-making and Debate in Committees

Author

  • Dessein, Wouter

Abstract

I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements (proposals) and costly state verification (discussions). I show that by favouring one particular agent ? the leader ? authoritative decision-making reduces rent-seeking discussions and often results in a higher decision-quality relative to majority decision-making. Institutions which guarantee a "right to voice" by separating the roles of decision maker and discussion leader may further improve efficiency.
