Information Cascades with Endogenous Signal Precision
Information cascades rely on individuals’ own information being sufficiently imprecise that they ignore it, in favor of information inferred from others’ observed behavior. This paper extends the standard information cascade model to allow individuals to choose how precise they want their information to be, when additional precision may be costly. There are two main results. First, free riding ...
متن کاملAggregate information cascades
We introduce a new model of aggregate information cascades where only one of two possible actions is observable to others. Agents make a binary decision in sequence. The order is random and agents are not aware of their own position in the sequence. When called upon, they are only informed about the total number of others who have chosen the observable action before them. This informational str...
متن کاملSelf-correcting Information Cascades
We report experimental results from long sequences of decisions in environments that are theoretically prone to severe information cascades. Observed behavior is much different—information cascades are ephemeral. We study the implications of a model based on quantal response equilibrium, in which the observed cascade formation/collapse/formation cycles arise as equilibrium phenomena. Consecutiv...
متن کاملAttenuation of noise in ultrasensitive signaling cascades.
Ultrasensitive cascades often implement thresholding operations in cell signaling and gene regulatory networks, converting graded input signals into discrete all-or-none outputs. However, the biochemical and genetic reactions involved in such cascades are subject to random fluctuations, leading to noise in output signal levels. Here we prove that cascades operating near saturation have output s...
متن کاملInformation Cascades on Arbitrary Topologies
In this paper, we study information cascades on graphs. In this setting, each node in the graph represents a person. One after another, each person has to take a decision based on a private signal as well as the decisions made by earlier neighboring nodes. Such information cascades commonly occur in practice and have been studied in complete graphs where everyone can overhear the decisions of e...
