Organizations design their communication structures to improve
decision-making while limiting wasteful influence activities. An efficient
communication protocol grants complete-information payoffs to all organization
members, thereby overcoming asymmetric information problems at no cost. This
paper characterizes efficient protocols assuming that: (i) some agents within
the organization have the knowledge required for optimal decision-making; (ii)
both the organization and consulted agents incur losses proportional to the
exerted influence activities; and (iii) informed agents can discuss their
strategies before being consulted. Under these assumptions, "public advocacy"
is the unique efficient communication protocol. This result provides a novel
rationale for public advocacy
