  We consider an ecological system governed by Lotka-Volterra dynamics and an
example of an economic system as a mesomarket with perfect competition. We
propose a mechanism for cooperative self-regulation that enables the system
under consideration to respond properly to changes in the environment. This
mechanism is based on (1) active individual behavior of the system elements at
each hierarchical level and (2) self-processing of information caused by the
hierarchical organization. It is shown how the proposed mechanism suppresses
nonlocal interaction of elements belonging to a particular level as mediated by
higher levels.
