  We examine the statistical properties of a closed monetary economy with
multi-aggregates interactions. Building upon Yakovenko's single-agent monetary
model (Dragulescu and Yakovenko, 2000), we investigate the joint equilibrium
distribution of aggregate size and wealth. By comparing theoretical and
simulated data, we validate our findings and investigate the influence of both
micro dynamics and macro characteristics of the system on the distribution.
Additionally, we analyze the system's convergence towards equilibrium under
various conditions. Our laboratory model may offer valuable insights into
macroeconomic phenomena allowing to reproduce typical wealth distribution
features observed in real economy.
