Abstract
A deterministic system of coupled maps is proposed as a
model for economic activity among interacting agents.
The local maps represent the wealth of the agents.
The dynamics of the system is controlled by two parameters.
One parameter expresses the growth capacity of the agents
and the other describes the local environmental pressure.
For some values of the parameters, the system exhibits
nontrivial collective behavior, characterized by macroscopic
periodic oscillations of the average wealth in the system,
emerging out of local chaos. The probability distribution of
wealth in the asymptotic regime shows a power law behavior
for some ranges of parameters.
