Abstract
Privately informed individuals speak openly in front of other members of a committee about the desirability of a public decision. Each individual wishes to appear well informed. For any given order of speech, committee members may herd by suppressing their true information. With individuals of heterogeneous expertise, optimizing over the order of speech can improve the extraction of information, but not perfectly so. It is not always optimal to use the common anti-seniority rule hereby experts speak in order of increasing expertise. A committee with more able experts may be afflicted by greater herding problems, yielding a worse outcome.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
