    The Power Law and Critical Density in Large Multi Agent Systems

    CPM Report No.: 00-71
    Date: 8th May 2000

    Abstract

    Agents that act as information brokers in large
    distributed systems (such as the internet) lower
    the cost of obtaining information. Agents have
    direct access to only a small part of such systems at
    any one time. This paper investigates the
    conditions in which agents successfully go through
    other agents in order to establish direct
    communication. A simulated, large information
    market enables agents to acquire the information
    they seek if and only if market shares amoung
    broker agents conform to a power law distribution.
    This result, if it turns out to apply more generally,
    implies that agency theory based on utility
    maximisation does not provide any guidance to
    system properties. Thus certain aspects of the
    agent decision making process are implied by the
    properties of the system.
