Decision making in committees : transparency, reputation and voting rules

In this paper I analyze the e¤ect of the transparency of the decision making process in committees on the decisions that are eventually taken. I focus on committees whose members are motivated by career concerns, so that each member tries to enhance his own reputation. When the decision making process is secretive, the individual votes of the committee members are not exposed to the public but only the …nal decision. Thus, individuals are evaluated according to the group’s decision. I …nd that in such a case, group members are induced to comply with preexisting biases. For example, if the voting rule demands a supermajority to accept a reform, individuals vote more often against reforms and exacerbate the conservatism of the voting rule. When the decision making process becomes transparent and individual votes are observed, this e¤ect disappears and such committees are then more likely to accept reforms. I also …nd that coupled with the right voting rule, a secretive procedure may induce better decisions than a transparent one.
