Abstract

Aggregation is commonly associated with loss of information. In contrast, this paper shows that aggregation can actually enhance information down‐the‐road by deterring information cascades. In particular, when hierarchical tiers forward only aggregate recommendations rather than nitty‐gritty details, it increases the uncertainty faced by subsequent tiers. This makes individuals at higher levels more willing to rely on and convey their own views rather than simply rubber stamping suggestions from lower levels. Copyright © 2006 John Wiley & Sons, Ltd.
